One hundred twenty-six isolates of Trichoderma spp., belonging to the fungal collection of the Department of Tree Science, Entomology and Plant Pathology “Giovanni Scaramuzzi”, University of Pisa, were screened for their mycoparasitic ability against sclerotia of Sclerotium rolfsii and Sclerotinia sclerotiorum. Isolates belong to the Pachybasium, Longibrachiatum, and Trichoderma Sections and included T. asperellum, T. atroviride, T. aureoviride, T. crassum, T. effusum, T. erinaceum, T. fasciculatum, T. flavofuscum, T. hamatum, T. harzianum, T. helicum, T. koningii, T. minutisporum, T. oblongisporum, T. polysporum, T. rossicum, T. saturnisporum, T. sinensis, T. stromaticum, T. velutinum, T. virens, T. viride, Hypocrea hunua and Trichoderma sp. An isolate of Clonostachys rosea was also tested. Some species were represented by only one strain. Mycoparasitic activity was expressed according to the percentage of decayed or infected sclerotia. Distribution of mycoparasitic ability according to the taxonomic position of Trichoderma spp. isolates was evaluated
Mycoparasitism against sclerotia of Sclerotium rolfsii and Sclerotinia sclerotiorum is widespread within the genus trichoderma

Abstract
One hundred twenty-six isolates of Trichoderma spp., belonging to the fungal collection of the Department of Tree Science, Entomology and Plant Pathology “Giovanni Scaramuzzi”, University of Pisa, were screened for their mycoparasitic ability against sclerotia of Sclerotium rolfsii and Sclerotinia sclerotiorum. Isolates belong to the Pachybasium, Longibrachiatum, and Trichoderma Sections and included T. asperellum, T. atroviride, T. aureoviride, T. crassum, T. effusum, T. erinaceum, T. fasciculatum, T. flavofuscum, T. hamatum, T. harzianum, T. helicum, T. koningii, T. minutisporum, T. oblongisporum, T. polysporum, T. rossicum, T. saturnisporum, T. sinensis, T. stromaticum, T. velutinum, T. virens, T. viride, Hypocrea hunua and Trichoderma sp. An isolate of Clonostachys rosea was also tested. Some species were represented by only one strain. Mycoparasitic activity was expressed according to the percentage of decayed or infected sclerotia. Distribution of mycoparasitic ability according to the taxonomic position of Trichoderma spp. isolates was evaluatedI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
