Peach leaf curl is a plant disease characterized by distortion and coloration of leaves and is caused by the fungus Taphrina deformans, [1] which infects peach, nectarine, and almond trees. T. deformans is found in the United States , Europe , Asia , Africa , Australia , and New Zealand . [ 2 ]
In the United States, $2.5 to 3 million dollars are lost because of peach leaf curl. Sixty to ninety percent of peach shoots in Italy can be infected by T. deformans. [14] Although peach leaf curl is mostly manageable with fungicide spraying in dry climates, [4] improper timing or incomplete coverage of the crop can result in control failure. [11]
One of the more commonly observed species causes peach leaf curl. Taphrina typically grow as yeasts during one phase of their life cycles , then infect plant tissues in which typical hyphae are formed, and ultimately they form a naked layer of asci on the deformed, often brightly pigmented surfaces of their hosts.

Peach trees are prone to a disease called leaf curl, which usually does not directly affect the fruit, but does reduce the crop yield by partially defoliating the tree. Several fungicides can be used to combat the disease, including Bordeaux mixture and other copper-based products (the University of California considers these organic treatments ...
Environmental conditions play a large role in the ability of Taphrina species because they are highly dependent upon leaf surface moisture to infect budding leaf tissue. A similar species to T. caerulescens is the more studied T. deformans (causing leaf peach curl) which requires temperatures to be less than 16 and 19°C in the infection and ...
