Heliothine Trap Counts, June 8, 2018
Bollworm trap catches rose sharply this week, especially in the Delta, signalling the beginning of another generation. Moth emergence is aligning with corn silking this year which is bad news. While economic damage to corn is minimal, larvae develop very
Heliothine Trap Catches, June 1, 2018

I have recently received a few call about slugs in corn. I suspect this will increase in more crops as planting continues and they begin to emerge. Slug problems usually start on corn first, then move to soybeans, then cotton in our area.
