First report of Sclerotinia sclerotiorum on potato plants in Iran

Abstract

After observing severe symptoms of Sclerotinia sclerotiorum on the lower parts of potato plants (cultivar Agria), some sclerotia were observed and sampled. During sexual and asexual stages of this fungus, some morphologic characteristics of this pathogen were studied and its pathogenesis on cultivar Marfona was proved by a new method. This is the first report of Sclerotinia sclerotiorum on potato in Iran. © 2009 Australasian Plant Pathology Society.
