Powdery mildew caused by Oidium neolycopersici L. Kiss is one of the most important diseases of tomato under polyhouse conditions. During 2014-15, polyhouses of Kangra district (H.P., India) were surveyed and the disease severity was observed between 5.0 to 89.5 per cent affecting both quality and quantity of the harvest. Fourteen hybrids/cultivars of tomato were screened under p house conditions during 2014-15 cropping season, but all were found either susceptible or weakly resistant against powdery mildew. | Nội dung Text Evaluation of IDM components for management of tomato powdery mildew under protected cultivation
