Soybean podworm is also known as the corn earworm. Early planting will greatly reduce problems with this pest.
Podworms feed on leaves or developing pods. Pod injury can be very serious if these insects are numerous in a field. Podworm infestations develop in July and August, usually in fields where the plants have not formed a closed canopy over the rows.
Soybean podworms or fall armyworm infestations should be treated when defoliation levels exceed those listed in Table 2. If pod feeding is occurring, treat when populations reach 2 per row foot.
