Golden Pest Spray OIl for cane berries when to spray?
I've got 147 fairly large plants of mostly boysenberries with a few thornless blackberries as well. Last year, I got a nasty case of red berry mites, so this year I bought a gallon of Golden Pest Spray Oil, which is supposed to do the trick. I'm told that I should spray at 5 tablespoons per gallon, but I'm not sure WHEN to spray. Before bloom? After bloom? (the latter sounds unlikely, wouldn't I damage the flowers?). Anyway, if somebody knows, please respond. Thanks!
p.s. should I add a spreader/sticker to the spray solution?
