My peach tree has brown rot. Can I do a chlorine wash now? I need to know the recipe too, as I am going to treat it spring.
Chlorine for Brown Rot
Certified GKH Gardening Expert
I have heard of chlorine being used to wash post-harvest fruit with this problem, but never on the tree itself. I would not recommend treating the tree with chlorine. This article has some other suggestions: https://www.gardeningknowhow.com/edible/fruits/peach/brown-rot-fungus.htm You might try neem oil as well. It is a good, organic fungicide.
