We have been battling fungus with our trees since we’ve planted them. It seems to occur in almost all 6 varieties that we have. During the fall and dormant season, we’ve sprayed copper fungicide and dormant oil in hopes to minimize fungus and other pests. All trees are leafed out now that it’s warmed up, and most of the tree leaves are exhibiting the leave curl. What can I spray on them while they have fruit that’s safe? Captan fungicide? What concentration would you recommend? Thank you!

HobbitWife has peach trees. Her contact at the state Extension Office says Neem Oil is good.
She uses Neem Oil for most all of her insecticide needs, from her garden greens to the chickens (it kills the mites).
NOT SAFE FOR BEES! So she sprays at night while they are tucked into their beds.

While we don't know what to spray, my wife picks off the curled leaves and disposes of them. What new leaves come out are mostly ok. The trees look kinda funny but they're still alive and even still bear some fruit.

What i have read is you have to spray in the fall, and again in the spring before the leaves come out

Hard to treat in season without ruining the fruit. Had it really bad in my peaches, so I sprayed three times over the winter with copper fungicide and dormant oil. Leaf curl is 99% gone this season.
