I use 3 cups per gallon, with some Dawn, some Neem, some Triazide, and I’ll be using some vinegar in the future in 1 or 3 gallon hand pump sprayers.
I wasn’t all that happy about using Triazide, but the Lowe’s I went to didn’t seem to have any Malathion products and I really wanted to get out ahead of the PC this year. Last year I lost 99% of my apples to them. I only intend to use it on the tree fruits, and only once or twice. PC seems to be my only insect issue.
