Fall armyworm is a major maize pest in warm regions, and it spreads quickly.
Scout early
Walk the field weekly from emergence. Look for windowpane feeding on young leaves, fresh frass (sawdust-like droppings) in the whorl, and egg masses on leaf undersides. Act when a set share of plants show fresh damage.
Target small larvae
Young larvae feed on the whorl; sprays or biological products reach them best at this stage. Large larvae hide deep and are harder to kill.
Integrated options
- Early, uniform planting so the crop is not at different stages.
- Natural enemies and bio-pesticides (e.g. Bt) where available.
- Resistant or tolerant hybrids if on offer.
- Rotate insecticide groups and follow safety rules.
Neighbours' cooperation helps; the moth flies long distances.
