My orchard has various varieties of prunus and malus specie trees affected by bacterial spot, bacterial cankers, peach leaf curl, cedar-apple rust, cedar-quince rust, fire blight and phytophthora and pythium in soil. Will Junction handle all these fungal problems? Furthermore, will fruit from these trees be edible next growing season after these fungal infections have been killed?
