[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.
[2] Conidia produced under the favorable conditions are spread from primary source by wind or rain to infect developing young susceptible twigs, fruits, or leaves of peach plant.
[7] Fruit infections take place during early development since conidia begin to produce and peak around calyx split and bloom.
As noted earlier, epidemic development heavily depend on successful dispersal of conidia produced from primary inoculum.
[9] The primary cause of peach scab, Cladosporium carpophilum, can be found primarily in the Southern portion of the U.S. but still poses a threat in the Midwest.
[7] Peach scab is easily controlled by dispersal and application of generic fungicides, so most occurrences appear in home orchards, and rarely does the disease pose a threat in commercial environments.
Due to the effectiveness of fungicide application and its relatively minor damage to crops, there are few cultural controls and no resistant peach variants that have been developed for the current market.
For prevention of peach scab, proper pruning of leaves to allow adequate sunlight will drastically reduce the risk of infection and propagation.
[7] Due to widespread use of fungicides, Peach scab does not pose a large threat to commercial growers of stony fruits, and is primarily a disease that is found in home orchards.
Historically, the disease is believed to have originated in Austria, but is now a minor presence for all peach trees typically east of the Rocky Mountains.
