Lannate should be used if both species are present. Processing snap beans should be sprayed at the bud and pin stages with Orthene for corn borer control. In the Greenwood area, sprays should be applied on a 5-day schedule from the pin spray until 5 days from harvest. In the Bridgeville area, sprays are needed on a 4-day schedule from the pin spray until harvest. Fresh market snap beans should be sprayed on a 7-day schedule from the pin stage until harvest.
Aphids remain active, especially in fields where only a pyrethoid has been used.
If aphid populations are starting to increase, Lannate or Orthene should be used. Fresh market silking sweet corn should be sprayed on a 3-4 day schedule throughout the state. Be sure to check whorl stage corn for larvae feeding in the whorl. If Ambush, Pounce or Baythroid is being used as a silk spray, they should be alternated with Lannate or Larvin for fall armyworm control.
