We had a some hail last spring and pretty much every crabapple and apple in the area has fireblight. Many are completely covered to the point where sanitation pruning is almost not an option because the entire canopy has fireblight. Is there anything that can be done I have looked into copper sprays and ArborOTC. Should we spend the time to prune out all of the infected branches? (probably not economically feasible due to the time it would take) Will sprays or injections actually prevent the spread or are the trees goners?
