I wasn't quick enough to treat my peach trees from the peach curl which they developed a year ago. I sprayed them in the early spring with a copper fungicide, but the curl came back pretty strong. As the leaves were emerging, I stripped off the obviously infected ones and I sprayed with a seaweed concentrate solution. This was about three weeks ago. The tree is loaded with developing peaches but many leaves are infected. Is there anything else I can do now? Strip more leaves? Spray again with seaweed?
There is little that can be done in spring with regards to spraying for Leaf Curl.
Thinning the fruit load can help.
