I just read an article in the WSJ today about large pumpkin growers. There latest thing is to use aspirin. Salicyliac acid on there plants to prevent disease. They say that a couple of aspirins crushed into a gallon of water and then sprayed onto their plants helps to prevent disease. These guys are real serious growers of huge squash. Like 1500 pounds. It may be something to think about. Has anyone else heard of this?
