How to Identify, Prevent, and Treat Peach Leaf Curl
Peach leaf curl is a fungal disease that affects peach trees, as well as nectarines and almonds, causing the leaves to pucker and curl, turn red, and drop prematurely.
Peach Leaf Curl is caused by a fungal pathogen, Taphrina deformans, that overwinters on the tree’s bark and buds. In spring, the spores are released and are carried by wind and rain to infect new growth. The spores infect new leaves within a day or two after they emerge from the bud, and the disease develops during periods of cool, wet weather.
The infected leaves turn yellow, then red or purple, and become distorted and crinkled. Infected leaves often fall off the tree, leading to a reduced yield of fruit.
The fungus then produces a second set of spores on the fallen leaves, which can then reinfect the tree in the following season.
These symptoms typically appear in the spring after wet weather conditions.
Here are some ways to control and prevent Peach Leaf Curl:
It is important to note that prevention is key, as it is difficult to control the disease once it has been established.
