Gliocladium catenulatum: hyperparasite ofSclerotinia sclerotiorumandFusariumspecies

摘要

Gliocladium catenulatumparasitizesSclerotinia sclerotiorumandFusariumspp. It kills the host by direct hyphal contact causing the affected cells to collapse or disintegrate. Pseudoappressoria are formed by the hyperparasite but hyphae derived from them do not penetrate the host cell walls. Vegetative hyphae of all species tested and macroconidia ofFusariumspp. are susceptible to this hyperparasite but chlamydospores ofFusarium equisetiare resistant.
