Kelly Tindall, an entomologist at the University of Missouri Delta Research Center, says populations of Japanese beetles are building up in ditch banks and turnrows in southeast Missouri. “We’re also catching a lot of corn earworms in our traps, and we have some reports of fall armyworms in whorl stage corn, which is early for us.”

Producers have reported stink bug building up in roadside weeds, according to Tindall. “Aphids are starting to pop up in cotton. We’re also hearing about problems with herbicide carryover, which adds another stress on plants.”
