With recent rains, snap beans are at risk of Pythium pod rot. Recently the EPA approved Ridomil Gold Copper for use on Pythium pod rot in both Maryland and Delaware. Begin applications when Pythium pod rot first occurs and continue on a 7 to 10-day schedule. Apply 1 pack of Ridomil Gold Copper (5 lbs product)/2.5 acres. Ridomil Gold Copper has a 3 day PHI, and there is a limit of four applications per season.

Vegetable Crop Insects

Cabbage
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 will be needed for worm control.

Peppers
Be sure to maintain a 5 to 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. In addition, the highest labeled rates may be needed if population pressure is heavy in your area.

Spinach
Both webworms and beet armyworms are active at this time and controls need to be applied when worms are small and before they have moved deep into the hearts of the plants. Also, remember that both insects can produce webbing on the plants. Generally, at least 2 applications are needed to achieve control of webworms and beet armyworm.

Sweet Corn
With the high corn earworm catches throughout the state, all fresh market silking sweet corn should be sprayed on a 2-day schedule.
