Byron, it beats me why someone would use $20 worth of beneficial nematodes to protect a crop worth $1. If you want radishes, they're 25 cents a bunch at the market. Maybe we all ought to stop identifying the "insect" sight unseen and suggest she take a radish to her county agent and find out what's to blame.
