[Photo] Photo [Management] To prevent peach leaf curl, treat the trees every year after leaves have fallen (late November). Copper-based fungicides, tribasic copper sulfate, calcium polysulfides, metallic copper, or synthetic fungicides can be used. However, to be effective, copper-containing compounds must have at least 50% copper; those containing less do not adequately control leaf curl despite advertising claims. If timed properly, a single fall/winter spray will normally prevent losses. In areas of high spring rainfall or when spring rainfall is abundant, it may be advisable to apply a second copper spray or a lime sulfur treatment in spring, preferably before buds begin to swell, but definitely before budbreak (when green color is first visible). Fungicides containing chlorothalonil also work well at this time.
Leaf Curl Caused by the fungus Taphrina deformans. One of the most common disease problems for backyard gardeners. The distorted, reddened foliage that it causes is easily seen in spring. When severe, the disease can reduce fruit production substantially.
