My baby apricot tree is infected (I think) with Brown Rot. The little green fruits have moldy spots on them, the branches have gaping cankers, and the bark has dust all over it. What do I do??? The information on the websites say to prune out infected branches they all have cankers! I would have to prune it all down to a stub. Also it is right next to my fig and cherry trees. Their branches touch each other. Will they become infected too?
