The Fall Armyworm is a destructive pest that targets maize. Originally from the Americas, it has spread to Africa, Asia, and beyond. This pest feeds on maize leaves, stems, and cobs, causing severe damage to yields.
Fall armyworm in maize symptoms
- Small holes: Small worms feed on leaves, creating small holes or "window panes"
- Ragged leaves: Larger larvae consume more leaf tissue, causing leaves to appear ragged or torn
- Moist sawdust-like frass: Larvae leave behind moist sawdust-like frass near the funnel and upper leaves
- Damage to tassels and ears: Larvae may attack the tassels and/or ears of corn, causing ragged-edged holes
- Damage to the ear: The ear may be partly or totally destroyed
- Defoliation: FAW defoliation can be severe during the late pre-tassel stage.
