I get so many good tips from my fellow gardeners! This one came from the Back Yard Nursery Forum that I belong to. We are all having problems this summer with aphids, ants, Leaf hoppers, etc. I posted my fear that Sevin dust and spray is killing our bees and butterflies. In reply one of the members posted the following Mother Earth News link. This is a good substitute for Sevin and other harmful sprays. It is cheap too! Remember, if we kill the pollinators (and we will with Sevin) we will not have vegetables or fruit!
