Peach scab, also known as peach freckles, [1] is a disease of stone fruits caused by the fungi Cladosporium carpophilum. [2] The disease is most prevalent in wet and warm areas especially southern part of the U.S. as the fungi require rain and wind for dispersal. [3] The fungus causes scabbing, lesions, and defoliating on twig, fruit, and leaf ...
Leaf curl. 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] Peach leaf curl reduces the amount of leaves ...
Taphrina amygdali (Jacz.) Mix (1936) Taphrina deformans is a fungus and plant pathogen, and a causal agent [s] of peach leaf curl. [ 1] Peach trees infected with T. deformans will experience leaf puckering and distortion, acquiring a characteristic downward and inward curl. Leaves will also undergo chlorosis, turning a pale green or yellow, and ...
Shot hole disease is a major concern of the stone fruit industry. It is estimated that 80% of the California almond crop may be infested with shot hole disease, resulting in a potential yield loss of 50-75%. [3] In the 1930s, it was found that applications of Bordeaux mixture reduces shot hole disease on peaches from 80% to 9%.
Wells et al., 1987. Xylella fastidiosa is an aerobic, Gram-negative bacterium of the genus Xylella. [1] It is a plant pathogen, that grows in the water transport tissues of plants (xylem vessels) and is transmitted exclusively by xylem sap-feeding insects such as sharpshooters and spittlebugs. [1][2][3][4] Many plant diseases are due to ...
Leucostoma canker is a fungal disease that can kill stone fruit (Prunus spp.). [ 1 ] The disease is caused by the plant pathogens Leucostoma persoonii [ 2 ] and Leucostoma cinctum [ 3 ] (teleomorph) and Cytospora leucostoma and Cytospora cincta [ 4 ] (anamorphs). The disease can have a variety of signs and symptoms depending on the part of the ...
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 ...
