I haven't been to this thread for a while. I have 9 Cherokee Purple, 3 Better Boy, 2 Tasti-Lee, 2 German Giant and some scrumptious sweet corn.
Today while weeding and mulching I found some army worms that my brother warned me about. In the pic you can see where he was chewing on the whorl. I noticed 6 plants that have the whorl gone.
I also have some of these. Looks like some kind of parasitic wasp. While reading about the armyworm the article mentioned that some parasitic wasp feed on them. Wondering if this is one of those kind. If so apparently there is not enough to control them.
