Written by Courtney Ligon, Mercy Olmstead, and Phillip Harmon, and published by the UF Department of Horticultural Sciences, June 2015.
Peach scab is a disease caused by the fungus Cladosporium carpophilum. The pathogen can infect other fruits and nuts within the Prunus species, like almonds, apricots, nectarines, and plums. Peach scab is common during periods of humid weather because rain splashes the conidia (asexual spores) from the fungus between leaves, twigs, and fruit in the tree canopy, which spreads the disease.
