I have grown carrots for many years. For the past three years, my carrots have had small holes in them. I took some sample carrots to a local nursery and they identified the damage as being caused by the carrot rust fly larva. They recommended some actions I could take, which I tried last season but the carrots were still attacked. Here are the two recommended actions: 1. Although I do not like to use pesticides, I tried applying "Sevin", several times during the growing season but that did not solve the problem. 2. Alternately, I purchased a carrot seed variety called "Fly Away" marketed by Thompson and Morgan. This variety is supposed to be resistant to the rust fly larva but they were also attacked. Does anyone have a solution to this problem?
