peach leaf curl despite kocide
Comments (5)Sorry to hear about your bad luck. I had a similarly difficult problem getting rid of shothole on my peaches and plums, it took me four years and I almost ripped 'em all out at one point. What you did should work for a "normal" curl outbreak so you must have it particularly bad. I would focus on the fall sprays more, that is when the curl is lodging in the new buds (and getting effectively hidden from future sprays). Spray first when half the leaves have fallen, again when all leaves down, and a third a few weeks later. My victory over shothole was finally achieved with fall sprays. Curl is very different, but I do think this is the best point to get diseases to keep them from overwintering. I would also use lime-sulphur for half of the sprays, copper for the other half: hit it from every angle you can. My shothole is almost completely under control, but in the end I had to almost completely topwork the two plums which were the most susceptible: Elephant Heart and Howard Miracle. They would get it bad and then spread it to the other trees. Scott...See Moreleaf curl!
Comments (2)Andred: Unfortunately, nothing stops peach leaf curl once it is underway. The best you can do is to hope for a change in the cool, rainy weather and regrowth of the leaves. Prevention is the key to peach leaf curl control, and that can be achieved in a normal year by dormant sprays with copper. Bordeaux mixture does contain copper sulphate, but I prefer Kocide, which is copper hydroxide, as a dormant spray. But even with several dormant sprays, curl can appear when the weather conditions favor it, and that is the unfortunate case this spring. You can apply Bordeaux mixture, but I am afraid you will not notice much difference at this point. Keep your peach tree pruned so that it is able to dry out quickly between rains in the spring. That will retard development of the curl, and also help your peaches, which require sunlight to size up and sweeten. I am pruning my peach trees heavily right now, just at thinning time, to allow more light on the fruit. Open up the center. Darkness is the enemy of peaches and peach trees.
