I've read this thread with great interest, trying to avoid using copper or other non-holistic treatment on several4 year old apple trees that were devastated by scab last summer. 1 of these is my favorite, Eden variety crab with amazing flavor, one that I can eat down to the seeds and stem. The first 3 growing seasons it thrived, I thought it was suddenly mortally ill last summer.
