Most of the products mentioned don't handle brown rot. Sure I can use the products, as a number of fungi like peaches. I have used actinovate. It's just the synthetic stuff works and works well on brown rot, and just about everything else. Though I would settle for even a 50% yield. Monterey Fungi Fighter gives me about 98% fungus free fruit. Even my organic friends have given up and use it. Year after year of no fruit, they had enough and are now happy. Best example is Scott on gardenweb. he grew peaches for 12 years organically before he switched. It is a major problem for now. Scott grows everything organically, except peaches and some plums. We do use organic fertilizers and such. I still have some chemical fertilizers, and will use them for now, but soon will try and eliminate them. See how it goes.
