Estimation of loss in grain yield in sorghum genotypes due to downy mildew

, : Estimation of loss in grain yield in sorghum genotypes due to downy mildew. Indian Phytopathology 44(4): 520-522

To estimate the loss in grain yield of various sorghum cultivars due to Peronosclerospora sorghi infection, crops were protected from infection by seed treatment and 1 spray with metalaxyl, or were inoculated with the pathogen. During 1985 and 1986 the percentage systemic infection of downy mildew was greater in unprotected than in protected plots and the grain yield was lower, although differences were observed between the cultivars.
