Peach Tree

Question

I have a peach tree and it has these dark round balls on some of the branches. Can you tell me what they are?

Answer 1

It sounds like galls or a fungus of some type, possible even black knot. A fungicide may help. This article will help determine if black knot is infecting your tree: https://www.gardeningknowhow.com/edible/fruits/plum/black-knot-tree-disease.htm
