Peach leaf curl is caused by a fungus belonging to the sac fungi.
Peach Leaf Curl (Taphrina deformans) is caused by a fungus belonging to the sac fungi (Ascomycota). The spores of the fungus hibernate on the bark of the tree. When the temperature rises above 10 °C, the spores become active and infect the tree. If the temperature rises to 16°C, the infestation stops. Rain spreads the germinating spores across the tree. During a humid period, the fungus reaches full maturity and the infection becomes visible. The young leaves swell, turn red, develop bumps, curl and become covered with a fungal layer. Wind and rain then spread the spores.
