Badly affected cherry tree.

kathy meinig asked 11 years ago

This is a photo of my cherry tree. The bottom branches are badly affected but further up they are ok so far. I have sprayed in the last day with rose clear. Will this help or are there other solutions?

This is shot-hole diesase, probably caused by the blossom wilt fungus, sclerotinia. The fact that most damage has occurred lower on the tree would indicate that the lower levels are more damp and the top of the tree dries out more quickly. Rose clear is not effective against this. Try a spray of Liquid copper or Bordeaux mixture in October and  at bud break in spring.
