  • El Niño 2026/27: What Malawian Farmers Should Verify and Do Now

    El Niño 2026/27: What Malawian Farmers Should Verify and Do Now

    A first shower can persuade a family to plant expensive seed. If moisture has reached only the soil surface, germination may begin and then fail during the next dry days. The safer response to El Niño is not panic. It is to separate what has been confirmed from what still needs a Malawi forecast.

    What is confirmed as of 19 August 2026

    NOAA is the National Oceanic and Atmospheric Administration of the United States. Its Climate Prediction Center watches the Pacific Ocean and atmosphere to identify El Niño and estimate how the event may develop. The NOAA advisory issued on 13 August 2026 says El Niño is strengthening and gives a greater than 90 percent chance of a very strong event during the Northern Hemisphere autumn and winter of 2026/27.

    A Malawian farmer should care because NOAA provides an early warning that seasonal risks may be changing. However, its global advisory cannot provide a planting date or rainfall total for a Malawian district. NOAA also says impacts associated with an event of this strength become more likely, but are not guaranteed.

    DCCMS is Malawi’s Department of Climate Change and Meteorological Services. It is the official national service that monitors Malawi’s weather and turns climate information into seasonal outlooks, district information and short-term bulletins. A local farmer should care more directly about these products because they cover Malawi and are updated closer to the farm decision. Check the latest DCCMS seasonal outlook and 10-day agrometeorological bulletin, then record the issue date. A new bulletin should replace an older one in your decision.

    Three checks before maize goes into the soil

    1. Check the official local outlook. A global El Niño advisory is context, not a district forecast.
    2. Check moisture at planting depth. Open several stations after rain. The ridge should be moist below the surface, not wet only on top.
    3. Check the next 10 days. Use the latest DCCMS bulletin and local extension advice before committing seed and labour.

    No national calendar date can complete all three checks for every field. Use the practical measuring and emergence steps in Kumunda’s maize planting and spacing guide.

    Prepare the field without assuming drought

    Repair ridges, tied ridges, infiltration basins or drainage channels only where they suit the slope and soil. The aim is to slow useful rain without trapping destructive runoff. Keep clean crop residues as surface cover where plant-health advice allows. Do not burn automatically.

    Residue cover can reduce exposed soil, but diseased material should be managed with local plant-health advice.

    Use mature compost or well-rotted manure on an area you can finish properly. Map weak, sandy, eroded and waterlogged patches before allocating scarce material. Kumunda’s field-by-field soil fertility plan explains how to avoid one blanket treatment.

    Protect the seed decision

    Choose legally sold seed whose maturity period and recommendations fit your area. Ask the supplier or extension officer what the label means for the expected season. Early maturity or drought tolerance can reduce some risks, but neither guarantees a harvest.

    Compare maturity period, intended zone and label instructions before buying. An open bowl of grain is not proof of certification.

    Where land, food needs and labour allow, spreading risk across maize and a suitable legume may be safer than depending on one crop. Do not introduce an unfamiliar crop only because it is described online as drought resistant.

    Plan water, livestock and fertiliser together

    Late or uneven rain affects household water, livestock feed and crop residues at the same time. Repair safe water storage and troughs before demand rises. Decide which clean residues can remain as soil cover and which are genuinely needed for feed.

    Farmer storing livestock fodder beside goats, a covered water drum and a clean trough
    Fodder and protected water are part of the same dry-spell plan as field moisture.

    Do not respond to an El Niño advisory by increasing or reducing fertiliser blindly. Product, rate and timing still depend on crop, soil, moisture and current local guidance. See Kumunda’s maize fertiliser placement guide after confirming the local recommendation.

    A seven-day farm decision board

    Write down Question to answer Action if uncertain
    Forecast source and issue date Is this global, national or district information? Check DCCMS or ask extension
    Rain received Did moisture reach planting depth in several stations? Wait and check again
    Seed variety and maturity Does the label fit the local season? Ask the supplier or extension officer
    Field constraint Is the priority runoff, rapid drying or waterlogging? Treat the identified patch, not every field alike

    Decisions farmers may face

    Does El Niño mean every Malawian field will have drought? No. A global ENSO phase changes risk, but Malawi’s current forecast and district products are needed for local planning.

    Should I plant after the first useful-looking shower? Check moisture below the surface and the current short-term bulletin first.

    Should I buy extra fertiliser now? Not because of the El Niño label alone. Confirm crop area, product, soil need, moisture and current extension guidance.

  • Maize Fertiliser in Malawi: Basal and Top-Dressing Guide

    Maize Fertiliser in Malawi: Basal and Top-Dressing Guide

    Fertilizer gives the best return when the right product is applied at the right time and kept where maize roots can reach it. The rate should not be copied blindly from another farm. Malawi’s soils and rainfall patterns vary, and a recommendation that suits one area may waste money or damage plants in another.

    Use this guide to plan the work, then confirm the final rate with your local extension officer. If a soil test is available, use it to guide the choice of nutrients.

    Basal fertilizer and top dressing do different jobs

    Basal fertilizer is applied at planting or soon after emergence. It supplies nutrients needed for early root and plant growth. Top dressing is applied after the crop is established and mainly supplies nitrogen for rapid leaf and stem growth.

    The Malawi Ministry of Agriculture farmer field school handbook gives an example programme of 100 kg per hectare of 23:21:0+4S as the basal fertilizer, followed by 150 kg per hectare of urea at 3 to 4 weeks after emergence. This is an extension example, not a universal prescription. The correct product and rate are area and crop specific.

    Do not substitute DAP, NPK, CAN, or urea simply because the bag is available. These products contain different amounts and combinations of nutrients. Ask an extension officer to translate the local recommendation into the product sold in your area.

    Basal fertilizer placed away from maize seed in a planting furrow
    Place the measured basal fertiliser beside the planting position and keep it from direct contact with seed.

    When to apply fertilizer

    At planting or just after emergence

    Apply the recommended basal fertilizer at planting or within the early establishment period advised locally. The Ministry handbook describes application at planting or about 5 to 7 days after planting.

    Keep fertilizer away from direct contact with seed. Place it to the side of the planting position and cover it with soil. Direct contact can injure seed or young roots. Follow the spacing and depth demonstrated by an extension officer for your ridge and planting system.

    Three to four weeks after emergence

    Top dress when maize is growing actively, commonly around 3 to 4 weeks after emergence. Do not rely only on calendar days. Check that the stand is established and that the soil has useful moisture.

    Malawi research shows that timing and split nitrogen applications can improve nitrogen use. If local advice calls for a split dose, follow the stated stages.

    Avoid applying urea to very dry soil, waterlogged ground, or immediately before heavy runoff is likely. Apply when there is soil moisture and a reasonable chance of gentle rain, then cover or incorporate the fertilizer as locally recommended.

    Extension officer demonstrating a calibrated fertilizer measure to a farmer
    Use one calibrated measure consistently; handfuls and unmarked containers produce uneven rates.

    Step-by-step application

    1. Confirm the recommendation. Check the product, rate, timing, and field area with an extension officer, then read the bag label. 2. Measure the field. Convert a hectare rate correctly for the actual plot size. 3. Use a calibrated measure. Household cups, bottle tops, and handfuls vary too much. 4. Protect yourself. Wear gloves and closed shoes, wash after handling, and store bags away from children, animals, food, and water. 5. Place and cover. Apply a consistent amount in the recommended position, away from seed and stems, then cover it with soil. 6. Keep records. Note the product, amount, field, date, rainfall, and crop stage.

    How to avoid common losses

    • Do not apply a blanket rate without checking local advice.
    • Do not place fertilizer directly on seed, leaves, or stems.
    • Do not guess the measure or change products without recalculating nutrients.
    • Do not apply all nitrogen early when a split application is recommended.
    • Do not top dress a severely drought-stressed or waterlogged crop.
    • Do not treat manure as a fixed replacement for fertilizer. Nutrient content varies with material, storage, and decomposition.

    Well-prepared manure or compost can improve soil structure and add nutrients. Apply it early enough to mix with the soil, and ask for advice on how it changes the mineral fertilizer requirement. A soil fertility plan should combine crop residues, legumes, manure or compost where available, and carefully targeted fertilizer.

    Frequently asked questions

    Can I apply urea when the soil is dry?

    Wait for suitable soil moisture and local rainfall advice. Urea left on a dry surface can be poorly used, while heavy rain can move nutrients away from the root zone.

    How close should fertilizer be to a maize plant?

    It should be close enough for roots to reach but not touching seed or stem. Placement varies with the planting system, so use the spacing and depth demonstrated by your extension officer.

    Can manure replace all mineral fertilizer?

    Not by a fixed percentage. Manure quality varies widely. Compost and manure improve soil health, but a soil test or local recommendation is needed to decide whether extra nitrogen, phosphorus, sulphur, or other nutrients are required.

    Good fertilizer management is precise, timely, and local. Confirm the recommendation, measure accurately, protect seed and stems, and keep records. Those steps reduce wasted inputs and give maize a better chance to respond.

    Plan the next field check

    Confirm plant population with the planting and spacing guide. If crop response remains uneven, map the weak patches using the soil fertility plan and test pH before assuming that more fertiliser is the answer.

  • Soil pH in Malawi: How to Test and Improve It

    Soil pH in Malawi: How to Test and Improve It

    Why can a crop remain weak after fertiliser? One reason may be soil pH, which affects nutrients and biology. A pH result is not a complete lime recommendation. Collect a representative sample and interpret it with local advice.

    Why soil pH matters

    FAO explains that soil reaction influences nutrients and microbial activity. Many nutrients are available in moderately acidic soil, but the target depends on crop and location. Strong acidity can reduce nutrient use and increase aluminium or manganese risks. Alkaline soil creates different problems and should not receive lime.

    Soil acidity matters in parts of Malawi, particularly high-rainfall and high-altitude areas. CIMMYT and CGIAR report that lime returns vary with acidity, yield potential, price and transport cost.

    How to Test and Improve Soil pH in Malawi, supporting image 2

    How to collect a representative sample

    A result is only as useful as the sample. Ask the laboratory or extension office for its required depth, quantity and container, then use a consistent method.

    1. Separate areas where soil, slope, crop history or management differs. 2. Avoid termite mounds, manure heaps, edges, wet depressions, paths and spill sites. 3. With a clean auger, hoe or spade, sample several points in a zigzag at the requested depth. 4. Mix samples from one uniform area in a clean bucket. 5. Remove stones and large plant material, then retain the required amount. 6. Label the sample with field, depth, date, previous crop and intended crop.

    Testing options

    The strongest option is a recognised testing service that reports its method and provides an interpretation or lime requirement. A calibrated pH meter can provide screening information when the operator uses a consistent soil-to-solution ratio and standard buffer solutions.

    Record the test method and solution used; different methods are not directly interchangeable.

    Agricultural extension worker and Malawian farmer checking a soil pH meter and recording the result
    Record the sample location and reading; a pH result becomes useful only when it can be tied back to the correct field section.

    How to read the result

    Use the laboratory’s interpretation first. The following bands are only a broad orientation based on FAO soil-reaction classes.

    pH result Broad interpretation Practical next step
    Below 4.6 Extremely acidic Seek a laboratory lime requirement and extension advice before treatment.
    4.6 to 5.5 Strongly acidic Check crop needs and request a lime recommendation based on the soil.
    5.6 to 6.5 Moderately acidic Often suitable for many crops, but confirm the target for the intended crop.
    6.6 to 6.9 Slightly acidic Usually no automatic reason to apply lime; use the full soil report.
    7.0 or above Neutral to alkaline Do not apply lime simply to raise pH; seek advice on any diagnosed constraint.

    pH alone cannot determine a lime rate. Reserve acidity, texture, target pH and the liming material affect the requirement; buffered clay soil can require more than sandy soil for the same change.

    Improving acidic soil safely

    Apply agricultural lime only after testing and a laboratory or extension recommendation. Check neutralising value and fineness because equal weights of different materials may not work equally. Use dolomitic lime only when the result also supports magnesium.

    Measure field area and rate carefully. Spread the calculated amount evenly and, where appropriate, mix it into topsoil before planting. Lime reacts gradually and does not replace fertiliser, manure, erosion control or good management. Retest when advised instead of applying it every season by habit.

    Residues, compost and manure support soil condition but do not replace a confirmed lime requirement. Avoid ash at unknown rates; its strength varies and excess can disrupt nutrient balance.

    Mistakes to avoid

    • Sampling only the easiest corner of the field.
    • Using dirty tools or fertiliser bags that contaminate the sample.
    • Treating a cheap field-kit reading as a precise lime recommendation.
    • Applying lime without measuring the field or checking its quality.
    • Assuming more is better; over-liming can reduce some nutrients.
    • Mixing lime directly with fertiliser unless current product and extension guidance specifically permits it.
    • Expecting lime to solve poor drainage, erosion, low organic matter or every nutrient deficiency.

    Turn the result into a field decision

    Record the sample location and result on the same field map each season. Use the result with the soil fertility management plan; if maize nutrition is the next decision, continue to the fertiliser placement guide. A pH number alone does not determine a fertiliser or lime rate.

    Frequently Asked Questions

    What soil pH is best for maize?

    Maize often performs well in moderately acidic soil, but the target depends on variety, soil and test method. Follow laboratory and extension advice.

    Can I test soil pH at home?

    A calibrated meter or colour kit can screen soil when used carefully. Before buying lime, submit a representative sample and request a lime requirement.

    Does low pH mean I should apply lime immediately?

    Not automatically. Confirm the result, identify the intended crop and obtain a rate that considers soil texture, reserve acidity and the liming product.

    How quickly does agricultural lime work?

    It reacts gradually. Speed depends on fineness, moisture, mixing, soil properties and product quality. Follow the timing given with the laboratory or extension recommendation.

    Should every field receive the same lime rate?

    No. Fields with different soil, slope or management history may have different pH and lime requirements. Sample and manage them separately.

  • Maize Planting in Malawi: Dates and Spacing for 2026 and 2027

    Maize Planting in Malawi: Dates and Spacing for 2026 and 2027

    A bag of good maize seed can still produce a poor stand when it is planted into dry soil, washed out by a heavy storm, or crowded into uneven stations. The difficulty is that there is no single calendar date that guarantees success across Malawi. The practical decision is to prepare early, watch local conditions and plant when enough moisture has entered the soil not simply when the first clouds appear.

    When should maize be planted?

    For Malawi’s main rain-fed crop, planting normally follows the establishment of seasonal rains. FAO’s Malawi reporting shows why farmers should respond to field moisture rather than trust a fixed date: the onset can be delayed and rainfall can remain erratic even after the season appears to have started.

    Prepare land, seed and measuring materials before the expected rains. After rain, check whether moisture has penetrated to planting depth. A light shower that only wets the surface may be followed by several dry days, leaving germinating seed without enough water. Local weather advisories and guidance from an extension officer should therefore take priority over a national calendar.

    Maize Planting Dates and Spacing in Malawi, supporting image 2

    How location changes the decision

    Rainfall onset, temperature and length of season vary with altitude and location. The table below is a planning guide, not a prescription.

    Agro-ecological setting District examples Practical planning point
    Lower and hotter areas (Chikwawa, Nsanje, Balaka) Southern low-altitude fields Prepare early and act on dependable soil moisture; heat can dry shallowly wetted soil quickly.
    Mid-altitude plateau (Lilongwe, Kasungu, Mchinji, Zomba) Central and southern plateau fields Follow local onset reports and confirm moisture at planting depth before sowing.
    Cooler highlands and northern uplands (Dedza, Ntcheu, Mzimba, Rumphi) Higher and cooler fields Match planting to local rains and the maturity period of the selected variety.

    Farmers should also read the seed label. A variety’s maturity period affects whether it fits the expected season. For broader crop planning, see Kumunda’s complete guide to growing maize in Malawi and soil fertility management guide.

    Practical maize spacing

    A commonly used target is 75 cm between rows and 25 cm between planting stations, with one established plant per station. If every station establishes, this arrangement gives roughly 53,000 plants per hectare. Treat it as a starting pattern, not a universal instruction: the seed variety, soil fertility, moisture availability, ridge system and current Ministry or extension recommendation may require adjustment.

    Farmer measuring maize planting stations with a marked rope and wooden stick in a prepared Malawian field
    A marked rope and fixed measuring stick reduce spacing differences between workers and rows.

    A field-ready planting method

    1. Finish land preparation before dependable rains. Repair ridges where used and control established weeds. 2. Measure rows. Cut a rope or stick to the recommended row distance. Keep rows as straight and evenly spaced as the field allows. 3. Mark stations. Mark the planting rope at equal intervals so workers do not estimate every hole by eye. 4. Check moisture. Open a sample hole and confirm that soil is moist at sowing depth. 5. Plant uniformly. Follow the seed label and local extension guidance for depth and seeds per station. Cover seed with soil without leaving it exposed. 6. Inspect emergence. Walk the field after germination, noting missing, crowded or washed-out stations. Ask an extension officer whether gap filling is still worthwhile; late replants can mature unevenly.

    Mistakes to avoid

    • Planting after one weak shower without checking moisture below the surface.
    • Waiting for a fixed date while dependable local rains are already established.
    • Estimating spacing by footsteps, which often produces irregular rows.
    • Dropping extra seed into every station “for safety” without planning to thin.
    • Mixing varieties in the same rows without understanding their different maturity periods.
    • Applying a national rule without considering the field’s zone, soil and current forecast.

    What to decide after spacing

    Spacing sets the plant population, but the field still needs a nutrient plan. Diagnose weak patches with the soil fertility field plan, then use the maize fertiliser guide for placement and timing.

    Frequently Asked Questions

    What is the best maize planting date in Malawi?

    There is no guaranteed date for every district. For rain-fed maize, prepare early and plant when effective seasonal rains have provided adequate moisture at planting depth, guided by local forecasts and extension advice.

    Is 75 cm by 25 cm suitable for maize?

    It is a common one-plant-per-station arrangement and produces about 53,000 established plants per hectare. Confirm it against the variety label and current local recommendation.

    Should I dry-plant maize before rain?

    Dry planting carries risk if rain arrives late or only wets the surface. Seek district-specific advice and use the latest seasonal forecast before choosing it.

    Can I put two seeds in a station spaced 25 cm apart?

    Not automatically. Two established plants at that spacing greatly change plant population and competition. Use the station spacing and seed number recommended for your variety and conditions.

    What should I do if some seed does not emerge?

    Inspect the cause first. Replanting late can create an uneven crop, so ask an extension officer whether gap filling is worthwhile at that stage.

  • Soil Fertility Management in Malawi: A Field-by-Field Plan

    Soil Fertility Management in Malawi: A Field-by-Field Plan

    Before the first planting rain, a farmer must decide where limited manure, legume seed and fertiliser will give the best return. Start with the weakest patches of the field rather than spreading every input too thinly.

    Soil fertility is not simply the amount of fertiliser applied. It also depends on soil organic matter, acidity, drainage, erosion and whether roots can reach water and nutrients. This guide helps Malawian farmers diagnose the main constraint and make a practical dry-season plan.

    Start with a field map, not a blanket rate

    Walk the field before clearing all crop residues. Mark areas where plants were consistently pale, short, waterlogged or scorched. Compare those patterns with slope, soil colour and previous manure or fertiliser placement. One poor plant may have pest or seed damage; a repeated patch usually points to a field condition worth investigating.

    • Pale older leaves: may indicate nitrogen shortage, but drought and damaged roots can look similar.
    • Stunted or purplish young plants: can be associated with limited phosphorus, cold soil or poor rooting.
    • Hard surface crust and rapid runoff: suggest weak soil structure and low protective cover.
    • Poor growth despite regular fertiliser: is a reason to test pH and review drainage, placement and timing.
    Adjacent field strips showing protected soil with residue cover and bare soil affected by surface runoff
    Compare cover, crusting and runoff between field sections before deciding where to concentrate soil-improvement work.

    Choose the correction that matches the problem

    What you observe Useful next check Possible response
    Sandy soil dries soon after rain Depth of topsoil and remaining residue cover Add decomposed organic material, retain safe residue cover and avoid excessive plant population
    Water remains after storms Drainage path and compacted layers Improve drainage and avoid working saturated soil
    Yield falls although fertiliser use is unchanged Soil pH, nutrient test and application method Use test results and local extension advice to adjust nutrients or lime
    Runoff removes soil on a slope Direction of ridges and exposed channels Slow runoff, protect the surface and repair erosion pathways

    A visual symptom is a starting point, not a laboratory diagnosis. If poor growth continues, follow the sampling method in our soil pH testing guide and ask the local Extension Planning Area office what testing support is available.

    Build organic matter without wasting scarce material

    Use well-decomposed manure or mature compost. Fresh manure can burn seedlings, carry weed seed and release nutrients at the wrong time. Keep the heap covered from heavy rain, but do not seal it so tightly that it becomes waterlogged.

    When there is not enough for the whole field, concentrate it in a measured strip or selected planting stations and leave an untreated comparison strip. That produces a useful farm trial and avoids pretending that a small heap can change every hectare equally.

    Legumes such as groundnut, soybean, pigeonpea and cowpea add diversity and can contribute nitrogen when nodulation and biomass are good. They do not automatically remove the need for other nutrients. Choose a rotation or intercrop that fits land, food and market needs.

    Use fertiliser as part of the plan

    Product choice and rate should follow the crop, field history, soil information and an up-to-date local recommendation. Do not copy a neighbour’s bag count: field size, fertiliser grade and soil condition may differ.

    Keep fertiliser away from direct contact with seed and stems. Apply into moist soil and cover it where the label and extension guidance require. For maize timing and placement, continue to the maize top-dressing and fertiliser guide.

    Lime is not a general fertiliser. It is used to correct acidity and the required material and rate depend on a soil test. Applying it without evidence can waste money or push pH too far.

    Malawian farmer allocating mature compost from a covered heap before the rainy season
    Protect mature compost and allocate it to measured field sections before the rains restrict access.

    A dry-season allocation plan

    1. Draw a simple field map and mark weak, eroded, sandy and waterlogged patches.
    2. Estimate available manure or compost using the same container each time.
    3. Choose one priority correction for each patch instead of applying every remedy everywhere.
    4. Reserve a short comparison strip so you can judge the response after harvest.
    5. Record product, amount, date, rainfall and crop response.
    6. Confirm fertiliser and lime decisions with current district guidance before buying.

    Decision checks before spending

    Should I buy lime because maize is yellow? Not from colour alone. Check roots, moisture, fertiliser placement and pH first.

    Can manure replace all fertiliser? Sometimes it supplies useful nutrients, but its nutrient content varies. Treat it as one part of the fertility plan and monitor the crop response.

    Which field should receive limited compost first? Choose a manageable area where low organic matter or rapid drying is the likely constraint, while avoiding patches whose main problem is flooding or severe erosion.

    This guide supports planning, not a field-specific prescription. Product labels and current advice from Malawi’s agricultural extension services take priority.

  • Botanical Pest Control in Malawi: A Safer Guide for Farmers

    Botanical Pest Control in Malawi: A Safer Guide for Farmers

    Two bottles of dark plant extract can look identical and still contain very different amounts of active material. One may reduce a pest; another may scorch leaves, affect beneficial insects or do nothing. That uncertainty not whether a treatment sounds “natural” is the central decision in botanical pest control.

    This method guide explains how to judge a botanical option without giving an unsafe universal recipe. For the broader identify, prevent and monitor framework, first use Kumunda’s integrated pest management guide.

    Contents

    Why Plant-Based Treatments Vary

    Botanical pest-control products contain substances derived from plants. Their effect depends on species, plant part, growing conditions, preparation, storage, target pest and application. Two homemade mixtures that look alike may not have equal strength.

    A peer-reviewed evidence review found that homemade botanicals can sometimes reduce pests, but results vary and health and environmental risks remain uncertain. Some plants can harm people, livestock, fish, pollinators or crops. This guide therefore gives no universal homemade recipe or dose.

    Under the Malawi Pesticides Act, the Pesticides Control Board registers and controls pesticides. If a registered botanical product is available, use it only for the crop and pest on its current label.

    Clean crop-scouting tools and records used before choosing a pest treatment
    Good records and correct identification should come before any treatment decision.

    Match the Treatment to the Problem

    Different problems can look alike. Caterpillars or beetles may make holes, while disease, water stress or poor nutrition can cause yellowing. A wrong treatment wastes money and can delay the correct response.

    Photograph the pest and damage, or take a safely contained sample to an agricultural extension officer. Record when damage began and whether it is increasing. Ladybirds, spiders, wasps and other natural enemies may be helping; broad or repeated spraying can remove this protection.

    Farmer-friendly field conditions that support crop scouting and pest prevention in Malawi
    Inspect several parts of the field; one damaged plant does not represent the whole crop.

    Evidence and Authorization Check

    Before using any botanical or conventional pesticide, confirm:

    1. The pest or disease has been identified.
    2. Fresh damage is increasing enough to justify action.
    3. Practical non-chemical measures have been considered.
    4. The product is currently authorised for that crop and pest.
    5. Every label direction can be followed.
    6. Required protective equipment is available.
    7. Children, livestock, water and beehives can be protected.
    8. Re-entry and pre-harvest intervals can be respected.

    If an important answer is unclear, pause and seek qualified advice.

    Reduce the Need for Treatment

    • Plant at the locally recommended time where practical.
    • Use healthy seed and suitable varieties from trusted sources.
    • Rotate crops when the pest and available land make rotation useful.
    • Manage confirmed pest hosts without leaving soil unnecessarily bare.
    • Harvest promptly and keep stores clean, dry and regularly inspected.
    • Avoid moving infested plants or grain into a clean field or store.

    Use an Authorized Product Safely

    Wear the protection stated on the label. Keep children and uninvolved people away from mixing and spraying. Never use food or drink containers, and never clear a blocked nozzle with the mouth.

    Do not spray in strong wind, before heavy rain or near wells, streams and ponds. Prevent drift onto homes, animals, neighbouring crops and flowering plants. Keep products in original labelled containers, locked away from food, seed and feed. Never reuse pesticide containers.

    If exposure causes illness, leave the source, follow the label’s first-aid directions and seek medical help promptly. Take the container or label when safe. Do not induce vomiting unless the label or a medical professional specifically instructs it.

    Record the Result

    Return after the recommended interval. Record fresh damage, pest numbers, beneficial insects and crop injury. Do not repeat treatment automatically; follow product limits and seek advice if control fails.

  • Fall Armyworm in Maize: How to Control It in 2026 and 2027

    Fall Armyworm in Maize: How to Control It in 2026 and 2027

    When maize is growing quickly in the rainy season, fresh leaf damage can appear almost overnight. Do not begin by spraying the whole field. First confirm the pest, inspect a useful spread of plants and combine practical controls. Fall armyworm management works best as an integrated plan, not as one product or one treatment.

    Fall armyworm control is one part of a wider farm strategy. Read our complete guide to integrated pest management in Malawi to connect scouting, prevention, natural enemies and safe control decisions across crops.

    Table of Contents

    How to recognise fall armyworm

    Look for fresh feeding on young leaves, ragged holes and moist, sawdust-like frass inside the maize whorl. Egg masses may occur on leaves, and small larvae can scrape the surface before larger larvae make more obvious holes. A suspected caterpillar should be identified carefully because other insects can also damage maize.

    Old holes remain visible after the caterpillar has gone, while fresh damage and live larvae show current activity. If identification is uncertain, take a clear photograph to an extension officer.

    Scout before deciding

    Walk through the field in a W or zigzag pattern and stop at several points. At each stop, inspect a consistent number of plants. Record the growth stage, number with fresh damage, presence of live larvae and whether natural enemies are visible. Repeat scouting regularly while maize is young, especially after new damage appears.

    Pheromone traps can indicate that adult moths are present, but they do not replace plant inspection. The decision to act should consider fresh damage, crop stage, larval size, weather, cost and local guidance. Ask the extension office which action threshold is approved for the district.

    Protect the crop and its natural enemies

    FAO recommends integrated fall armyworm management that combines measures while reducing unnecessary pesticide use. Plant at the recommended time, use suitable seed, maintain balanced soil fertility and manage weeds.

    Avoid routine broad-spectrum spraying. Ants, earwigs, spiders, beetles, parasitoids and other organisms can attack fall armyworm eggs or larvae. Spraying without a confirmed need can kill these natural enemies, expose people and livestock, and increase costs.

    Push-pull systems use a repellent intercrop such as suitable Desmodium and an attractive border crop such as Napier grass. Farmers interested in this managed system should obtain locally appropriate planting material and instruction.

    What farmers can do by hand

    In a small field, early infestations may be reduced by crushing egg masses and handpicking visible larvae. Wear gloves and do not ask children to handle caterpillars or treated plants.

    Do not pour soil, ash, detergent, oil or homemade mixtures into whorls without current extension advice. Concentration and crop safety are difficult to control. Record what was done and scout again.

    When pesticide use is considered

    Pesticide should be considered only after the pest is confirmed and local guidance indicates that treatment is justified. Under the Malawi Pesticides Act, pesticides are registered and controlled by the Pesticides Control Board. Registration and recommendations can change, so obtain the current Malawi-approved product and label instructions from an extension officer or authorised supplier. Do not use a product merely because it worked in another country or is sold under a familiar name.

    If treatment is advised, follow the label exactly, including dose, water volume, protective clothing, re-entry period and pre-harvest interval. Never mix products or increase the dose unless the label permits it. Keep people, animals, food, seed and water away from mixing and spraying.

    Young larvae are generally easier to reach than large larvae hidden deep in the whorl, which is another reason early scouting matters. Rotate modes of action only under qualified guidance; changing brand names does not necessarily change the active ingredient or resistance group.

    Mistakes to avoid

    • Spraying after seeing one damaged plant without inspecting the field.
    • Confusing old leaf holes with an active infestation.
    • Using an unregistered product or copying a dose from another country.
    • Applying a stronger mixture because the first spray did not appear to work.
    • Killing natural enemies through repeated calendar spraying.
    • Allowing children to mix, carry or apply pesticides.
    • Ignoring protective clothing, re-entry time or pre-harvest interval.

    Frequently Asked Questions

    Does every damaged maize plant need pesticide?

    No. Confirm fresh activity, inspect plants across the field and use the current local action guidance. Old damage can remain after larvae have disappeared.

    Can I control fall armyworm without chemicals?

    Early scouting, hand removal in small fields, timely planting, good crop management and conservation of natural enemies can all contribute. Results depend on crop stage and infestation, so continue monitoring.

    Do pheromone traps control the pest?

    Traps mainly help monitor adult moth activity. They do not show how many maize plants currently contain damaging larvae, so inspect the crop as well.

    Which pesticide should I buy?

    Use only a product currently registered and recommended in Malawi for the crop and pest. Ask an extension officer or authorised supplier and follow the approved label; this article does not prescribe a product or dose.

    Should I spray again if leaf holes remain?

    Not automatically. Old holes do not heal. Look for new feeding, live larvae and local guidance before deciding whether any further action is justified.

  • Integrated Pest Management for Malawi Crops

    Integrated Pest Management for Malawi Crops

    Integrated Pest Management, or IPM, helps farmers protect crops without spraying automatically whenever they see an insect or damaged leaf. The method begins with prevention, field scouting and correct identification. Farmers then compare crop loss with control costs and risks before choosing the safest response.

    Fall armyworm, stem borers, aphids, whiteflies, tomato leaf miner and storage pests do not affect every field in the same way. A decision based on evidence from your field is better than a recipe.

    Homemade mixtures are not automatically safe. Use locally validated guidance and consult an extension officer before applying any mixture to food crops.

    For a crop-specific example, see our practical guide to identifying, scouting and controlling fall armyworm in maize before deciding whether treatment is justified.

    What IPM Means

    IPM is not a single product and it does not aim to kill every insect. It combines compatible methods to keep pests below levels that cause unacceptable economic damage while reducing risks to people, animals and the environment. The basic cycle is simple: prevent, observe, identify, decide, act and check again.

    A World Bank-supported Malawi programme reported 61,788 adopters of integrated pest and disease management against a target of 15,000. It also warns that traditional methods are site-specific and may lack reliable information about quantities and environmental effects. Local knowledge should be tested and documented carefully rather than turned into one recipe for every farmer. Read the Malawi programme account.

    Prevent Problems Before They Grow

    Prevention lowers pest pressure and makes later decisions easier.

    • Use seed and varieties recommended for your crop and location by recognised Malawi extension or research services.
    • Plant at the locally recommended time and spacing so crops establish strongly.
    • Rotate crops where the pest or disease life cycle can be interrupted, and avoid relying on one control method every season.
    • Manage soil fertility, water and weeds so crops are not weakened by avoidable stress.
    • Remove or destroy confirmed infested material when extension guidance recommends it, but do not clear all residues automatically where soil cover is needed.

    Scout the Field Systematically

    Walk the field at least once a week during vulnerable stages, and more often when damage changes quickly. Do not inspect only the edge. For maize, the FAO fall-armyworm scouting guide recommends a W route with five stations of 10 plants 50 plants in total.

    Record the date, crop stage, number of plants checked, number with fresh damage, pests or eggs found, beneficial organisms present and any action taken. In maize whorls, fresh feeding and fresh frass are more useful than old holes on leaves. Revisit the same areas to learn whether the problem is increasing, stable or declining.

    Inspect fresh damage throughout the field and record what you find before deciding on control.

    Identify the Cause Correctly

    Different problems can produce similar damage. Inspect both sides of leaves, stems, growing points, roots or stored grain as appropriate. Photograph the insect and damage, or take a safe sample to an extension officer or plant clinic.

    For fall armyworm, look for fresh window-like or ragged feeding in the maize whorl and fresh frass. A developed larva may show a pale inverted Y on its head and four dark spots forming a square near the rear. Do not identify it from colour alone, and do not confuse old damage with a current infestation.

    Decide Whether Control Is Necessary

    Seeing one insect does not mean the whole field should be sprayed. Consider the crop stage, the proportion of plants with current infestation, whether damage is increasing, the crop’s ability to recover, the number of natural enemies and the expected value of the crop.

    There is no single action threshold for every crop, pest, district and season. Ask a local extension officer for the current recommendation when the decision could involve significant cost or pesticide use. FAO notes that fall-armyworm damage can look severe while maize may compensate, so treatment decisions should not be based on appearance alone. See FAO’s African IPM guidance.

    Use a Control Ladder

    When action is justified, begin with the lowest-risk effective method.

    Mechanical and physical

    Hand-pick egg masses or young caterpillars in a small plot, remove a confirmed infested plant when appropriate, or use crop-specific nets and barriers.

    Cultural

    Adjust planting practices, rotation, sanitation or crop diversity using locally validated advice.

    Biological

    Conserve predators, parasitoids and naturally occurring pathogens; use a registered biological product when one is approved for the crop and pest.

    Pesticide as a last resort

    Use only a product currently registered in Malawi for that crop and pest. Follow the label for dose, protective clothing, mixing, application, re-entry and pre-harvest intervals. Never increase the dose, combine products without approved instructions, reuse pesticide containers or buy an unlabelled decanted product.

    Under Malawi’s Pesticides Act, the Pesticides Control Board registers pesticides. Ask extension or the Board for the current register because registrations can change.

    Protect Farmers’ Friends

    Ladybird beetles, lacewings, spiders, ants, earwigs and parasitoid wasps can reduce pest populations. FAO scouting guidance encourages farmers to record these natural enemies alongside pest damage. Avoid unnecessary broad-spectrum spraying, especially when beneficial insects are already active. Flowering field margins can support useful insects, but plant choices should suit the farm and should not become weed or pest hosts.

    Where to Get Help in Malawi

    Take clear photographs, an affected crop part and your scouting notes to the nearest Extension Planning Area office, extension officer or available plant clinic. A 2025 study found that plant clinics strengthen diagnosis and extension services in Malawi, while noting shortages of trained staff and transport. Read the Malawi plant-clinic study.

    Malawi is also expanding digital pest surveillance with support from FAO and the International Plant Protection Convention, linking agricultural research, crop development and extension services. Read the 2026 FAO Malawi update.

    Frequently Asked Questions

    How often should I scout?

    Start with once a week during vulnerable stages and increase the frequency when fresh damage or pest numbers are changing quickly.

    Should I spray when I see holes in maize leaves?

    Not automatically. Check for fresh whorl damage, fresh frass and a live infestation, then consider crop stage, infestation level and natural enemies.

    Are homemade botanical sprays always safe?

    No. Strength, effectiveness and risks vary with the plant, preparation, crop and dose. Use only a locally validated recommendation and seek extension advice before applying an unregistered mixture to food crops.

    What if I cannot identify the pest?

    Do not guess. Photograph the pest and damage, keep scouting notes and ask an extension officer or plant clinic before spending money on control.

  • Don’t Wait Until Planting Season to Fix Your Farm Tools. By Then, It’s Already Too Late

    Don’t Wait Until Planting Season to Fix Your Farm Tools. By Then, It’s Already Too Late

    The same thing happens on farms across Malawi every year.

    The harvest is sold. Money is in hand. Then comes the spending: food, school fees, debts, and household needs. A few months later, when nursery preparations begin, a farmer reaches for the watering cans and finds rust, leaking seams, and handles that snap on first use.

    The tools they needed most are the tools they forgot to fix when they still had the money.

    This is not carelessness. It is a trap that catches even experienced farmers, and understanding it is the first step to breaking out of it.

    How Tools Get Damaged Without Anyone Noticing

    During the tobacco nursery period, a watering can works hard. It may be used twice a day, every day, for months, carrying water to seedbeds that need consistent moisture to produce healthy transplants.

    When the rains come and transplanting begins, the tools go quiet. That is when the damage starts.

    Watering cans end up in the kitchen, used for storing water. Hoes lean against outside walls through rain and sunshine. Sprayers sit for months without being cleaned, while their rubber seals slowly harden.

    By the time a farmer remembers these tools exist, they have been sitting in conditions that metal, rubber, and wood are not designed to survive for long.

    The damage is rarely dramatic. Rust at the joints. Cracks along the seams. Blocked nozzle holes. A loose handle. It does not look serious until you actually need the tool to work.

    Why the Start of the Season Is the Worst Time to Deal With This

    When tools fail at the start of a season, two things happen at once: you need them urgently, and you have little money left.

    The harvest income was spent months ago on more immediate needs. Now a farmer who could have repaired a watering can cheaply after harvest is buying a replacement at the start of the season, often at a higher price, often with limited options, and always in a hurry.

    Late buying is almost always more expensive than planned buying. In farming, where the window to prepare a nursery or plant on time is short, a broken tool does not just cost money. It can cost valuable time when every day matters.

    The Right Time to Act Is Right After Harvest

    For a few weeks after every harvest, most smallholder farmers have cash available and the next season still feels comfortably far away. This is the window. Most farmers let it pass without addressing their equipment.

    There are three things worth doing during that period.

    Inspect

    Walk through your farm and homestead and look at your tools. Check watering cans for rust and leaks. Check hoe handles for cracks. Check your sprayer, including the seals, nozzle, filter, and hose.

    Write down what needs attention. This takes less than an hour.

    Repair

    A loose handle, a leaking can, or a blocked nozzle may seem like a small problem, but small problems grow bigger with time.

    A local tinsmith can reseal a metal watering can. A carpenter can fit a new handle. Small repairs done now cost far less than replacements bought in a hurry later.

    Replace What Cannot Be Saved

    Some tools are beyond repair.

    Buy replacements while you still have time to compare options and budget properly. Waiting until the season starts often means paying more and settling for whatever is available.

    Simple Habits That Make Tools Last Longer

    Most tool damage is preventable.

    Store Tools Under Cover

    Rain and sunshine are the main enemies of metal, rubber, and wood.

    A storeroom, shed, or even a protected corner of a building can make a big difference. Tools left outside deteriorate much faster than tools kept dry.

    Keep Farm Tools for Farm Use

    Using a nursery watering can for household water storage is common and understandable. However, it shortens the life of the equipment.

    If possible, keep separate containers for household use and reserve farm equipment for farm work.

    Oil Metal Parts Before Storage

    Wiping hoe blades, ridger points, and other metal parts with a small amount of used cooking oil before storage helps slow rust.

    It only takes a few minutes and can significantly extend the life of your tools.

    Clean Sprayers Before Storage

    Chemical residue left in a sprayer can damage seals and block nozzles.

    Rinse the tank thoroughly, pump clean water through the nozzle, clean the filter, and store the sprayer empty.

    A clean sprayer is far more likely to work properly when you need it next season.

    Your Tools Make Farming Possible

    A farmer who reaches for a broken watering can at nursery time does not just lose a tool. They lose time.

    In farming, losing time at the start of the season can affect everything that follows.

    Think of your tools the same way you think about any valuable item that helps you earn a living. They are worth protecting because replacing them costs money and losing them at the wrong moment creates unnecessary problems.

    Farmers who inspect, clean, and store their equipment properly after each season are usually the same farmers who start the next season prepared.

    Mistakes Worth Avoiding

    • Using farm tools for household purposes without checking their condition before the next season
    • Waiting until nursery time to discover that equipment is broken
    • Ignoring small damage that becomes worse during storage
    • Treating tool maintenance as optional rather than part of normal farm management

    Key Takeaways

    • Inspect all tools within two weeks of selling your harvest
    • Repair small problems before they become expensive replacements
    • Store equipment under cover, away from rain and direct sunlight
    • Wipe metal parts with oil before long-term storage to slow rust
    • Clean sprayers thoroughly before putting them away
    • Keep farm tools for farm use whenever possible

    Conclusion

    The period immediately after harvest is short. Money is available, the next season feels distant, and it is easy to focus on other priorities.

    Yet a small amount spent on tool maintenance during that period can save money, reduce stress, and help ensure a smoother start to the next season.

    The tools that prepare your nursery, cultivate your land, and protect your crops deserve attention long before they fail.

    Fix them when you can, not when you must.

    Frequently Asked Questions

    When should farmers repair farm tools?

    Immediately after harvest when funds are available and before the next season begins.

    How should watering cans be stored?

    Store them under cover, away from rain and direct sunlight.

    Why do farm tools rust quickly?

    Moisture, rain, and poor storage conditions accelerate rust and damage.

  • Why Farmers Are Switching to Nano Urea Fertiliser in Malawi

    Why Farmers Are Switching to Nano Urea Fertiliser in Malawi

    Maize farming in Malawi continues to face rising fertilizer costs, unpredictable rainfall, and pressure to improve yields using fewer resources. Because of this, many farmers are beginning to explore alternative fertilizer technologies such as nano urea.

    Nano urea is a liquid nitrogen fertilizer designed to improve nutrient efficiency using smaller application quantities compared to conventional granular urea. Instead of applying large bags directly into the soil, nano urea is commonly sprayed onto crop leaves during key growth stages.

    One reason farmers are interested in nano urea is the possibility of reducing fertilizer wastage. Traditional fertilizers can lose nutrients through leaching, evaporation, or runoff, especially during heavy rains. Nano formulations aim to improve nitrogen absorption directly through the plant.

    Another advantage is easier transportation and handling. Carrying a small bottle is much simpler than transporting multiple heavy fertilizer bags across long distances.

    However, proper application remains extremely important. Farmers should carefully follow the recommended spraying instructions, dilution ratios, and timing guidelines provided by the manufacturer. Poor application practices may reduce effectiveness.

    Nano urea should also be viewed as part of a broader farming strategy that includes:

    • proper land preparation
    • good seed selection
    • weed management
    • irrigation where possible
    • soil health improvement

    As agriculture continues to modernize in Malawi, digital platforms are beginning to play a larger role in farmer education and product access. Farmers can now learn about products online before deciding whether they are suitable for their fields.
