Q&A – Why is there a white furry spot on my apple branches? There are also sores on the bark.
Question:
Why is there a white furry spot on my apple branches? There are also sores on the bark.
Answer:
This furry spot is the woolly apple aphid. It creates the fury cover around itself for protection from predators. It also protects it from insecticides. A small infestation will probably not be a problem except on young trees. There are also some root stocks that are resistant to the wooly apple aphid.
The other problem is more serious. The sores are cankers caused by black rot fungus. To deal with that, prune off all the affected branches at least six to eight inches below the canker.
Is the tree worth saving? It depends on how much work you want to put into it. Seeing that the tree has not grown in five years, it may be easier to start over with a tree that is more resistant to the wooly apple aphid and black rot.
