To effectively implement subsurface fertilisation, the following should be carried out. Use of briquette machines to produce 1 to 3 grams of briquettes that are larger than conventional fertiliser granules is recommended:

• Step 1: Prior to application, dig small holes 7 to 10 centimetres deep along planting rows in drained rice paddy or regular field, ideally located in the centre between a location where four plants will be planted.
• Step 2: Place the briquettes in the whole, below the soil surface, and cover with dug soil.
• Step 3: Crops should be planted within seven days of fertiliser application.

Following are the main steps for making your own briquettes. Making briquettes leading up to planting is more effective, as they are not stored for too long. A standard briquette machine can be purchased for between USD 3,000 and USD 6,000.

• Step 1: Collect manure from cow and/or horse waste.
• Step 2: Allow the manure to moderately dry (so it is possible to handle), but not for extensive periods, otherwise it will degrade. Keep manure out of direct sunlight, or when processing, remove the outer layer before manufacturing briquettes, and do not leave exposed, especially during rainy periods.
• Step 3: Press manure into briquettes using briquette press machine – see directions below to make your own home-press.
• Step 4: Allow the briquettes to dry in a cool, dry location, and store for later use.

To make your own large manure briquette press using household items, follow the instructions below:

• Step 1: Cut the top off a straight-sided 2-litre plastic soft drink bottle at the top of straight side.
• Step 2: Obtain a tinned food can that is just smaller than the diameter of the bottle. Preferably leave tin un-opened.
• Step 3: Line the bottle with a plastic bag.
• Step 4: Place slightly damp manure (cow, horse or both) inside the bag, inside the bottle, filling the space.
• Step 5: Place tin on top of manure.
• Step 6: Place small plank of wood on top of the tin.
• Step 7: Place your foot on top of the piece of wood, and slowly apply pressure to the tin, pressing the manure down, adding more manure if it compresses further than the depth of the tin.
• Step 8: When the manure will compress no more, remove plank and tin, and draw the compressed manure from the bottle, removing the plastic bag to reveal a cylinder of compressed manure.
• Step 9: Slice with a sharp knife to discs 2 to 3 cm thick, and use a piece of 2 cm diameter metal or plastic pipe to punch a hole through each disc. Reuse the
• Step 10: Allow to air dry as individual rings in a cool dry place. As soon as they are strong enough, you can hang the rings on wire to continue to dry. Use in fields within a month of manufacture. The ring increases surface area, and speeds-up the drying process.

To effectively leverage banding and micro-dosing for maize and sorghum, the following should be carried out. When handling fertilisers, always ensure that safety precautions provided on the packaging are followed.

Banding – suitable when wishing to save on fertiliser expenditure, but still need to improve production of primary and secondary crops.

• Step 1: Plough the field using a draught animal-drawn or mechanised plough to carefully open furrows. Depending on availability of mechanised equipment, a narrow hoe can also be used if manual labour is favoured. This can reduce workload and minimise soil disturbance but may require more effort.
• Step 2: Count furrows and measure length to ensure that you have sufficient fertiliser for area, based on recommended application amounts (see packaging or see advice from supplier).
• Step 3: Apply fertilisers as a strip or line (band) along the furrow.
• Step 4: Turn furrow back over ensuring that the fertiliser is present at a depth of 5-8cm below the soil surface and covered by the soil. The basal fertiliser should not touch the seed as it may burn it and disturb its germination.

Micro-dosing: suitable when fertiliser is in short supply.

• Step 1: in the field, at the time of planting, prepare small pits 5 to 8 cm deep where each seed is to be placed.
• Step 2: measure approximately 6 grams of fertiliser using a bottle cap or a three-finger pinch.
• Step 3: place the micro-dose in the small pits.
• Step 4: cover fertiliser with a small amount of soil, then place the seed. Cover fully with soil and water, or allow rain to wet the ground.
• Where manure is available, Zai pits can be used to improve organic matter at the same time. Prior to planting, dig the small pit and fill with manure. When rains begin, fertiliser and seed are placed in the hole and covered.
• The practice includes the advantage of banding by placing the fertiliser below the seed but at a single point instead of a row.

To effectively leverage integrated pest management:

• Step 1: Identify damage and responsible pest. Regular crop monitoring is important, to ensure early identification. Bottle traps are useful for capturing samples to examine and identify a pest.
• Step 2: Learn about the pest and host life cycle and biology.
• Step 3: Monitor or sample environment for pest population.
• Step 4: Establish action threshold. If aiming to tackle weed infestation, intervention must occur before the weed matures and begins spreading seeds. Some thresholds are high. For example, if dealing with caterpillars, soya beans can tolerate a certain level of defoliation without it impacting crop yield.
• Step 5: Identify IPM response tactics.
  • Cultural methods –planting crops that are adapted or suited to conditions and responding to their water, nutrient and shelter needs.
  • Physical methods – mechanical weeding, such as mechanical weeding or using organic or plastic mulch to cover the ground to reduce weed presence/success.
  • Genetic methods – selecting modified or adapted pest-resistant varieties.
  • Biological methods – using natural predators, push-pull approaches, intercropping, etc. and use of use of organic pesticides.
  • Chemical methods – considering all levels of toxicity – from pheromone deterrents to conventional pesticides.
• Step 6: monitoring for ongoing efficacy, and adjustment of tactics where relevant/necessary.  Aiming at all times to use chemical pesticides rationally and as a very last resort.

In the cases where chemical pesticides are used as part of an IPM strategy, the Agri-Intel website is an invaluable resource, which provides detailed chemical management advice: https://www.agri-intel.com.

To effectively leverage flooding irrigation:

• Step 1: prepare the field, digging parallel furrows and raising beds with the excess soil. Crops are planted in beds, and the irrigation water will flow in the furrows.
• Step 2: Using a pump or gravity fed water storage, allow water to flow into the field, flooding furrows.
• Step 3: Insert a fine mesh or introduce a hessian sack at the in-flow point to trap weeds and pests.
• Step 4: Water release should be moderated so as not to flow too fast and erode beds, and too slow such that it remains trapped at the in-flow point.
• Step 5: Water release can be more effective if released in surges, taking advantage of infiltration rates and capillary action in soil.
• Step 6: Observe progress. Avoid leaving soil crusts, which will make water rush over.

A sustainable water source must be identified and a pumping/irrigation system should be used.

To effectively leverage chemical use of organic control measures:

• Organic pesticides must be made based on the type of pests that attack the field along with their productivity rate.
• Equipment needed. Small measures (teaspoons or baking measures), plastic cup, plastic bucket (>1 litre), stirring rod or large spoon/spatula. Spray bottles or back-pack pump spray. Tools used in the field must be cleaned properly to avoid attracting other pests
• When spraying, wear goggles, gloves and disposable masks, and avoid spraying on windy or rainy days.
• It is recommended that any spray is tested before large-scale application. Spray and leave for 24 hours to see if treatment is effective.

a. Basic neem oil spray insecticide: effective against aphids, whiteflies, snails, nematodes, mealybugs, cabbage worms,  gnats, moths, cockroaches, flies, termites, mosquitoes, and scale.

• Step 1: Mix 1 cup of vegetable oil with 1 tablespoon of liquid soap in a plastic beaker or cup (cover and shake thoroughly),
• Step 2: When ready to apply, mix oil spray mix with 1 litre of water,
• Step 3: Pour spray mix into a spray bottles or a back-pack pump spray,
• Step 4: Shake thoroughly, and spray directly on the surfaces of affected plants. The oil coats the bodies of the insects, effectively suffocating them, as it blocks the pores through which they breathe.
  - Use mixture within eight-hours.

b. Garlic spray: a general organic insecticide that kills most insects.

To effectively leverage biological control and encourage natural predators:

• Step 1: Conduct regular monitoring using field walk-throughs and utilise bottle traps with various lures/baits to identify main pests on crops in order to identify any pests.
• Step 2: Once the pests have been identified, consult with national research institutes to identify the best natural predators, or biological control agents* to address the particular pests. It is critical to understand what options are available and costs associated with each option.
• Step 3: Implement according to advice received.
• Step 4: Monitor progress in terms of reduction in numbers and incidences.
• Step 5: Adjust the approach based upon observations from the fields.

A farmer must study the lifecycles of insect predators and be aware of pests that feed on his/her crops in order to identify the intervention that will the most effective in controlling pests at difference phases of their lifecycles. Farmers can create welcoming environments for certain predators to attract them to the field area

To effectively use mechanical bottle traps, the following should be carried out:

Bottle-trap

• Step 1: Obtain 2L plastic water or soft-drink bottles.
• Step 2: Rinse bottles thoroughly to avoid contents affecting lure.
• Step 3: Cut bottle horizontally using sharp scissors or knife, ensure that the top-half is slightly shorter than lower-half.
• Step 4: Turn the shorter top-half upside down and insert into lower-half ensuring the top- half does not touch the lower surface of the bottom-half.
• Step 5: Poke holes in both sides, penetrating both layers (top and bottom halves) and insert string, cord, or wire to create a handle.
• Step 6: Hang on tree branches or on thick wire or wooden stands around field perimeter and in larger fields within fields.

Specially designed all army worm traps can be purchased at agricultural suppliers. Farmers may also need a magnifying glass to identify insects.

Lures or bait

• Step 1: Identify the types of insect or pest you wish to lure, to ensure the correct mix.
  • For fall army worms, use a pheromone lure – which should be purchased from an agricultural supplier.
  • For maize stalk/stem-borers, again pheromone bait is the most effective.
  • Flies are attracted by sugar-based solutions, or protein (meat) based for carrion flies.
  • Fruit flies are attracted by ripe-fruit, cider vinegar, beer and wine.
• Step 2: Place 2 to 4 cm of lure at the bottom of the lower half of the bottle, depending on size of the bottle – the larger the bottle, the more lure. Ensure that the lure smell must be strong, but not too intense so that it attracts insects rather than chasing them away.
• Step 3: Use only one lure per bottle trap as more than one might cause contamination leading to ineffective attractants.
• Step 4: Clearly mark bottles indicating the type of lure in use – permanent marker pen.

Use of disposable gloves is advisable when handling lures.

Unopened pheromone lure packets should be kept in a cool, dry places – preferably a refrigerator.

To effectively implement  short term reactive practices:

• Step 1: Inspecting the crop regularly and systematically by walking through the field following an M-shaped pattern will ensure that the farmer does not just look around the edges, but also inspects in the middle of the field.
• Step 2: Farmers should carefully examine the crops for any signs of pests/diseases. They may be able to identify the presence of pests or disease through observing the following:
  • If the plant is wilted.
  • Are the leaves more yellow than usual?
  • Are the crops smaller than usual?
  • Do the leaves have spots?
  • Have parts of the plan died?
• Step 3: Once the foreign specie has been identified, the farmer should employ a method to eradicate the issue thoroughly and immediately.

To effectively implement continuous long-term use of cultural practices, the following steps, as part of the Integrated Pest Management (IPM)  should be carried out, but before taking any pest control action, IPM first sets an action threshold, a point at which pest populations or environmental conditions indicate that pest control action must be taken:

• Step 1: Inspection. The cornerstone of an effective IPM program is a schedule of regular inspections. This should be regular to identify any new visitors to your crop.
• Step 2: Preventive Action: regular inspections reveal vulnerabilities in your pest management program, steps can be taken to address them before they cause a real problem. One of the most effective prevention measures is exclusion, i.e., performing structural maintenance e.g by closing potential entry points revealed during inspection thereby physically keeping pests out and hence reducing the need for chemical control.
• Step 3: Identification: Different pests have different behaviours. By identifying the problematic species, pests can be eliminated more efficiently and with the least risk of harm to other organisms. Professional pest management always starts with the correct identification of the pest in question.
• Step 4: Analysis: Once you have properly identified the pest, you need to figure out why the pest is in your facility, e.g. food debris or moisture accumulation that may be attracting it? What about odors, through floors or cracks, etc.
• Step 5: Treatment Selection: Cultural or IPM stresses the use of non-chemical control methods, such as exclusion or trapping, before chemical options. When other control methods have failed or are inappropriate for the situation, chemicals may be used in least volatile formulations in targeted areas to treat the specific pests- use the right treatments in the right places, and only as much as you need to get the job done.
• Step 6: Monitoring: Constantly monitoring your facility for pest activity and facility and operational changes can protect against infestation and help eliminate existing ones. Your agricultural extension officer can assist you in technical advice to keep pests away.
• Step 7: Documentation: Up-to-date pest control documentation is important and could include scope of service, pest activity reports, service reports, corrective action reports, trap layout maps, lists of approved pesticides, pesticide usage reports and applicator licenses

To effectively implement vaccination campaigns:

• Step 1: Networks that notify farmers about upcoming vaccination campaigns must be established to promote the significance of vaccinating animals across the country. This can be promoted through government bulletins and community radio, utilising extension networks, village level administration, and traditional leadership.
• Step 2: Vaccination parks for cattle can be set up by veterinary officials to restrain livestock movement that might increase disease spreading.
• Step 3: Goats and sheep can be vaccinated at their locations where officials will move from one village to another to reach more population.
• Step 4: Training of personnel is important to ensure that vaccination is carried out before seasonal outbreaks and prevent the spread of disease.
• Step 5: Commence campaigns one month prior to the season when outbreaks are most common or upon notice of a disease incidence.
