Black Knot fungus on Chokecherry trees
Is it ever possible to rid a Chokecherry tree of Black Knot or is it best to cut it down? Aside from pruning and fungicide? Also is there a honey bee safe fungicide to use? Thank you so very much for your time and resource!
Whether your tree could or even should be saved depends on how far the disease has progressed. Here is information on the disease.

Not all products are the same and I cannot recommend anything. You have to read the label and always follow directions.
