Participants should understand and be able to explain the ways they can help prepare for and grow a more resilient maize crop.
A healthy maize crop can better withstand diseases and compensate for damage caused by diseases and pests including FAW, so that plant injury does not always lead to yield losses.
Watch
A very good presentation on agroecological approaches to FAW is provided by Dr Timothy Krupnik from CIMMYT/CGIAR.
Maintain healthy soil, including soil organic carbon, soil moisture and structure, and ensure adequate plant nutrition. Research shows that plants grown in healthy soils are less attractive to pests.
Use high-quality seeds and varieties well adapted to the local environment and which are vigorous in the face of pests and diseases.
Planting time can be critical, especially when faced with limited or irregular rainfall. Avoid late planting, and avoid staggered planting.
Consider using intercropping, trap crops and repellent crops which can help to reduce FAW infestation.
Optimise fertiliser use: avoid excessive nitrogen use, adding inorganic fertilisers to plants grown in poor soils may increase attack rates, as the high levels of free amino acids in the leaves are attractive to pests
Don’t panic! Maize plants can withstand significant damage by the Fall Armyworm – so become an expert on crop health and FAW to get the best and most sustainable results.
