Pests in Gardens and Landscapes

Seasonal development and life cycle—Entomosporium leaf spot

Entomosporium fungi that infect deciduous plants overwinter mainly as spores on fallen leaves or as mycelia within tissue. On evergreen hosts, the fungi may remain on leaves year-round. Fungi are spread from infected tissue or contaminated leaf litter to healthy leaves by splashing raindrops or overhead irrigation. The pathogens are most severe during wet weather, especially when it coincides with new plant growth.
