Continue to scout all fields for beet armyworm, fall armyworm, diamondback and cabbage looper larvae.
Continue to scout all fields for lygus bugs, stinkbugs, corn earworm, soybean loopers and beet armyworm. Multiple sprays will be needed for worm control.
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.
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.
Both garden webworm 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. We have also heard reports from New Jersey that they have started to see Hawaiian beet webworm moths in black light traps so be sure to watch carefully for this insect. Controls need to be applied early when worms are small and before significant webbing occurs. Generally, at least 2 applications are needed to achieve control of webworms and beet armyworm.
Although black light trap catches have started to decline with the cooler weather, pheromone trap catches were still high early in the week, therefore all fresh market silking sweet corn should be sprayed on a 2-day schedule.
