Corn earworm flights are quite variable around the state, but are generally heavy. Counts in pheromone traps are higher in the northern part of the state, with the LaPorte County trap reporting 1422 moths over a 7 day period last week. That’s about 20 X the threshold level. As I wrote in the last newsletter, growers need to be spraying frequently when silks are green during this period of time. If you are growing one of the Bt varieties, especially in the northern part of the state, I would still recommend at least a moderate spray program to ensure that you get the results you are looking for.
