Reddish Marks on Leaves of Fruit Trees

Anonymous added on July 20, 2013 | Answered

Peaches, plum, and grapevines get these reddish, maroon circles that get bigger and then make holes in the leaves. The leaves then turn yellow and fall off the trees. I see no insects of any kind. I use dormant oil in the spring then start a regular program of Reteone and Bordeaux mix as per instructions for each. The trouble seems to start in early July. We have had a lot of rain, so my spraying program has been off some. This has happened to me in the past. What can I do to keep my trees and vines healthy? Right now about 70% of the foliage is gone. My pear and apple trees look good.
