In terms of seed treatments, as I mentioned, lindane was taken off the market. Diazinon Lindane is a product farmers used up until 2004. Most of it was taken off the market in about 2001. The current insecticides that we have on our seeds are safer to farmers than the D and L, and probably more effective than D and L.
Foliar sprays, which might be used, don't address the seed maggot, wireworm, and grubs that exist in the soil along with what these insecticides are trying to actually help us save. I'm not aware of other products that are available to farmers.
