Have you ever noticed the leaves of your peach tree becoming curled and puckered and turning reddish or purplish? If you’ve seen this, you’ve likely had peach leaf curl.
Peach leaf curl is a fungal disease caused by Taphrina deformans. It is one of the most commonly encountered diseases of peaches and nectarines, especially in home plantings. While it primarily affects the foliage, it may also infect blossoms, young twigs, and fruit.
