What is peach leaf curl?

Peach leaf curl is a disease caused by the fungus Taphrina deformans. Infections lead to severe distortion of the leaves soon after leaf burst in spring.

Taphrina deformans infects peaches and nectarines, also almonds and occasionally apricots and ornamental Prunus.


You may see the following symptoms:

  • Crumpled, thickened and distorted leaves, often red in colour
  • A white bloom of fungal spores on affected leaves
  • Diseased leaves fall rapidly, leading to defoliation and loss of vigour
  • Shoots and fruits are occasionally attacked
