[Apple-Crop] More on FB

[Vincent Philion]

Hi!

I have no idea about the effect of copper content in soil on FB management. That’s a new one for me. I tried to look it up, but couldn’t find anything. 

For FB, removing “any” stress is not a silver bullet though. As mentioned in previous posts, some water stress can save your trees when FB strikes.

It cant hurt anything, This is midwest soil, is copper short in other area too?, I have learned that removing any stress from the tree will get you success, Lee Elliott Upstart Nursery, Winchester, Illinois
