Bacterial Leaf Shot - What to do?

General Fruit Growing
1

I have a Methley Plum that I am fairly certain has a moderate case of bacterial leaf shot. It dropped 50-75% of its leaves last year from leaf shot and I sprayed it with fungicide believing it to be fungal leaf shot, but it has reappeared again equally as strong this year. The tree has not suffered any lack of vigor - it is actually my most vigorous tree - but I would like to try to get rid of it.

I have read there isn’t a cure for the bacterial type and that copper can be used when dormant but is that all that can be done? (Aside from removing dropped leaves, twigs, etc)

Thanks

@CWC
The Kocide 3000 label lists Fall and leafbud break / green tip as the best application times for bacterial shot hole on Plum.

I’m curious if spraying with copper now will be of any help? I assume the fall application is due to conditions being right for it to spread with cooler wetter weather

Try spraying serenade or any other broad spectrum fungicide/bactericide along with regalia. Other option is to spray Zerotol 2.0 which is hydrogen peroxide with peroxyacetic acid.
