If an insecticide is needed, it may only be needed in spots. To control the cow pea aphid, apply Malathion or other recommended chemicals. In late planted crops, the cow pea aphid population should be monitored closely and treated if needed. Other insects that appear in late crops are stink bug and corn earworms. These insects, however, generally require no control.
Thrips often attack peas that are planted close to mature wheat fields.
However, no insecticides are generally required. Consult the Cooperative Extension publication, MP 144, for insecticides that may be used on peas. The herbicides Treflan, Dual and Poast may be used for grass control while Basagran and Pursuit may be used to control broadleaves. It is essential to spray broadleaf weeds early for effective control. Consult the Cooperative Extension publication, MP 44, for herbicides that may be used on peas.
