Over last several years, incidence of powdery mildew of parsley (Petroselinum hortense L.) was noticed on growing areas in Serbia (Serbia&Montenegro). The parasite occurred on leaves and petioles. Infected plants were covered with a whitish fungal mycelium, conidiophores and conidia. Younger and inner leaves were spotted at first with epiphytic mycelium; these spots soon coalesced, forming larger areas, and finally covered the entire matured leaf. Slight chlorosis but with no necrosis occurred even though plants were severely affected. Based on the morphological characteristics of sexual and asexual structures, the causal agent of parsley powdery mildew was identified as Erysiphe heraclei DC.
