I have to rotate fungicides on my trees and grape vines to avoid immunity. This is one that I use and it works great. But you have to stay on top of your spraying no matter what you use, I spray every 10 days or so with good results. Fast shipping from DMOPC too.

The only downside is I wish it was a little lower cost (of course!). Otherwise it is my go-to contact killer for black spot and other fungus. after all the recent floods in our area its really double-important, especially when teamed with a good systemic fungicide.
We researched what could be used to treat and infected tree. This product was highly recommended by a local expert forestry service. The support provided by “do my own” was outstanding. The person we spoke with was knowledgeable and extremely helpful. We don’t know if the product will cure the issue but we are confident that this is the best option to try. They provided expert guidance about how and when to apply and what to do if this doesn’t help. Thank you.
