Abstract : Twenty seven exotic and local mango 6-year-old germplasms were evaluated for their resistance to powdery mildew caused by Oidium mangiferae under natural conditions. Among the exotic germplasms, Pahutan produced 53% infected inflorescence. Totapuri and Agmamashu were free from infection. In local germplasms, 3% and 50.25% infected inflorescence were recorded in Prasadbhog and Golapkhas respectively. Baromashi was free from visible symptoms of the disease. The prevalence and severity of powdery mildew were found to be reduced effectively by 2 foliar sprays with sulfur (as Kumulus DF) at 2000 p.p.m. followed by propiconazole (as Tilt 250 EC) at 500 p.p/m. The highest fruit retention was also recorded from sulfur-treated plants.
