Abstract
Sclerotinia sclerotiorum (Lib.) de Bary and Sclerotinia minor Jagger are two of the species in the genus Sclerotinia found in Canada. While S. sclerotiorum is distributed country-wide and causes disease on numerous economically important crops including oilseeds, pulses, forage legumes, vegetables, and ornamentals, S. minor has only been reported on lettuce in Quebec and Ontario. During the past five decades, Canadian researchers have made a substantial contribution to the understanding of the biology and control of S. sclerotiorum and, to a lesser extent, of S. minor. This review summarizes the progress of Canadian research on Sclerotinia diseases in the past 50 years, with specific emphasis in the areas such as strain differentiation, epidemiology, new types of sclerotia, survival and germination of sclerotia, and biocontrol. Le Sclerotinia sclerotiorum (Lib.) de Bary et le Sclerotinia minor Jagger sont deux espèces du genre Sclerotinia trouvées au Canada. Alors que le S. sclerotiorum a une distribution pancanadienne et cause des maladies sur de nombreuses cultures d'importance économique, y compris des plantes oléagineuses, des légumineuses alimentaires, des légumineuses fourragères, des légumes et des plantes ornementales, le S. minor n'a été rapporté que sur la laitue au Québec et en Ontario. Au cours des cinq dernières décennies, les chercheurs canadiens ont contribué de façon substantielle à la compréhension de la biologie et de la lutte contre le S. sclerotiorum et, dans une moindre mesure, contre le S. minor. La présente synthèse résume les progrès accomplis par la recherche canadienne sur les sclérotinioses, au cours des derniers 50 ans, en mettant spécifiquement l'accent sur des domaines tel que la différenciation des souches, l'épidémiologie, les nouveaux types de sclérotes, la survie et la germination des sclérotes et la lutte biologique.Keywords
