A Technical Report from The Bartlett Tree Research Laboratories
Peach leaf curl is a springtime disease that occurs on peach, nectarine and related ornamental trees. High incidents of peach leaf curl are generally recorded during cool, wet springs after a mild winter has prevailed. The main form of damage is premature leaf drop. This weakens trees, making them more susceptible to other diseases and winter injury. Weakened trees also produce fewer fruit the following season. Yield may be further reduced when blossoms and young fruit become diseased.
