| PEACH LEAF CURL. Since this is the last regular issue of the BYGL in 2010, BYGLers would like to remind readers that autumn or early spring is the best time to treat for peach leaf curl. Leaf curl is a springtime disease that occurs on peach, nectarine, and related ornamental plants. The disease, though not a problem every spring, can be severe during cool, wet springs that follow mild winters. The leaf curl fungus damages peach trees by causing an early leaf drop. This weakens the trees, making them more susceptible to insect pests, other diseases, and to winter injury. Weakened trees also produce fewer fruit the season following heavy leaf curl infections. Yield may be further reduced when blossoms and young fruit become diseased and drop. Peach leaf curl is not difficult to control. Since the fungus survives the winter on the surface of twigs and buds, a single fungicide spray, thoroughly covering the entire tree, either in the autumn after 90% of the leaves have fallen, or in the spring before bud swell, will provide effective control. |
