Soybean Podworm

Soybean podworm is also known as the corn earworm. Early planting will greatly reduce problems with this pest.     


Damage

    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.


Recommendations

    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.
