Some form of growth on my quince tree. Its about 5 years old, has fruited but only a few quinces this time.

The tree appears healthy, full of healthy leaves. The growth is all through the branches.

Looks like the tree is affected by Black Knot, a type of fungal disease. Unfortunately, we do not have any registered product for this disease. Please read more about this disease and consider other cultural control from the following link:
