Q.peach and nectarine leaf curl
We sprayed in the fall and we are beginning to see peach leaf curl. What can we do now that the blossoms are on the trees and the fruit is growing?

Unfortunately, there is not much you can do at this point. Control is impossible once symptoms appear. It is recommended however, to "maintain tree vigor by thinning more fruit than normal, reducing drought stress with irrigation, and applying extra nitrogen fertilizer."
