Vegetable Crop Insects

Joanne Whalen, Extension IPM Specialist;

Continue to scout all fields for beet armyworm, fall armyworm, diamondback and cabbage looper larvae.

Lima Beans
Continue to scout all fields for lygus bugs, stinkbugs, corn earworm, soybean loopers and beet armyworm. Multiple sprays may be needed for worm control.

Be sure to maintain a 7-day spray schedule for corn borer, corn earworm, beet armyworm and fall armyworm control. You should also watch for flares in aphid populations.

Snap Beans
All fresh market and processing snap beans will need to be sprayed from the bud stage through harvest for corn borer and corn earworm control.

Continue to sample for webworm and beet armyworm larvae. Controls should be applied when worms are small and before webbing occurs. Generally, at least 2 applications may be needed to achieve control of webworms and beet armyworm.

Sweet Corn
Although corn earworm moth catches have started to decline fresh market, silking sweet corn should be sprayed on a 2 to 3-day schedule for the remainder of the season.
