Peach Leaf Curl Symptoms on Peach

IllustrationPeach Leaf Curl (fungus - Taphrina deformans): The peach leaf curl fungus infects leaves, flowers, and fruits. Infected leaves are characterized by puckering, thickening and curling. Diseased leaves become pale yellow to light green and shed after a short time. Fruit and blossoms shed when infected and are seldom observed by growers. Disease development is related to air temperature at the time buds are opening. If surface moisture is present and the air temperature is near 68 degrees F, infection can take place. Temperatures above 86 degrees F and below 40 degrees F inhibit the fungus. After symptoms are visible, control is impossible. Apply a fungicide at the beginning of dormancy and/or just prior to bud break.
