The Q&A Archives: ventura peach tree

Question: I have used the domate spray, when I was supposed to. Problem was I still got peach curl. I not only resprayed the peach tree,a couple of months ago but I also cut off the limbs that had peach curl on it. I've now noticed there is no peach bud in sight. Could I have hurt my tree for this year? The label on tree says

Answer: Peach Leaf Curl can affect leaves, flowers, tender shoots and even fruit. Diseased leaves eventually fall off, but unaffected leaves will grow on normally. Once you see the problem it is too late to correct it for that season. Sanitary measures certainly can't hurt, so you may want to collect and discard fallen, affected leaves, and to prune twigs with the small, seldom noticed swellings caused by the infection. Infection occurs in spring when temperatures are around 68 degrees and surface moisture is present on the buds. Therefore the problem doesn't occur every year with the same severity. The lowest toxicity option for effective control is to apply a copper fungicide at the beginning of dormancy in the fall. Copper will cause the peach to defoliate so that is why we wait until the leaves begin to fall to apply it. Note that copper can stain masonry blue, so be careful in applying the spray if your tree is near a sidewalk, rock wall of your home, etc. If you see no peaches developing, you wont' get any this year, but there is always hope for next year. Here's a publication explaining peach leaf curl and how to deal with it:

I hope this helps you get a head start on the disease for next year. Best wishes with your peach tree!
