sclerotinia stem rot (ssr), caused by sclerotinia sclerotiorum, is one of the most important diseases of canola (brassica napus) in golestan province, the leading canola producer in iran. in order to assess the yield loss of canola caused by ssr, 80 fields were surveyed in four different regions of the province (gorgan, ali abad, kalaleh and gonbad) during 2006-2007, and ssr intensity was recor...

Mycoviruses are viruses that infect fungi. A growing number of novel mycoviruses have expanded our knowledge of virology, particularly in taxonomy, ecology, and evolution. Recent progress in the study of mycoviruses has comprehensively improved our understanding of the properties of mycoviruses and has strengthened our confidence to explore hypovirulence-associated mycoviruses that control crop...

Sclerotinia sclerotiorum (Lib.) de Bary is a broad range fungal pathogen which attacks more than 500 species of higher plants (Boland and Hall, 1994; Saharan and Mehta, 2008; Sharma et al.,, 2015a). The pathogen can cause serious losses in yield and quality on numerous important field and vegetable crops (Purdy, 1979). Stem rot of Indian mustard caused by S. sclerotiorum (Lib.) de Bary has beco...

By Zahi Kanaan-Atallah, Ph.D. Washington State University May 2003 Chair: Dennis A. Johnson Sclerotinia sclerotiorum (Lib.) de Bary is a cosmopolitan, homothallic and necrotrophic ascomycetous fungus dispersed by airborne ascospores and soilborne sclerotia. It causes disease in over 400 host species. A significant correlation between potato yield losses and stem rot incidence has not been obser...
