The corn earworm traps from the Vegetable IPM program may be stored away for the winter, but the
vegetable IPM team is always thinking about CEW management. We want to bring sweet corn producers’ attention to a free webinar put on by a regional team of corn earworm experts that will cover
two important topics: Bt traits and silk sprays. Information below:
