I should have added that if a person is using any of the systemic insecticides, DON'T use them close to ANY food crop !! The iris I grow that live on the edge of the veggie garden DON'T get systemic, although I DO spray them with "BT" (thuricide) a few times a season ( but not during bloom time). These iris get "checked"for borer more than the others, and so far, I have seen no evidence of borer in those beds. I may try nematodes in these beds, as that would be a "food safe" control.....although if I let the veggie garden go completely over to iris..
