Hi, I have a 3 year-old, reliance peach tree grafted on 4 year-old root stock. The tree has some leaves that have red blotches on them that eventually kills the leaf. I spray the tree in the early spring before bud burst with lime sulphur and then with Wilson's Fruit Plus (contains phosalone and ferbam) as directed by their web site and by following the BC Ministry of Agriculture's recommendations. Because a picture is worth a thousand words, here are some photos showing the progression of the problem: It doesn't look like leaf curl, although I have found some leaves that are leathery and distorted. I wonder if this problem is Coryneum Blight or is it a mineral deficiency? I fertilize the tree in the spring with a Ross Root feeder using the 15-25-10 pellets. Anyone know what the problem could be? TIA
