Organicide info request
Maybe what I need is a insect friendly recipe for powedery mildew? I'm
loosing my squash and pumpkin plants because it's so bad.
Maybe bordeaux mix? I don't think it will hurt the insects much. But if
used heavily over a long period the copper may accumulate in soil to a
point where it becomes toxic to the plant. I think sulfur would also be
effective.
