I can ask my dad what we used to use on the trees. The neighbor sprayed ours. We only had 15 or so trees in a line and did some "Pick Your Own" but mostly we stashed enough in the basement to take us to the next April. I dunno if dad will remember. He is 89 and forgetting some of those things. In the back of my head, I am thinking maybe this was the spray of the 70's: http://en.wikipedia.org/wiki/D...
