Sunflower Helianthus annuus L. is one of the world’s most cultivated oil seed crop. And affected by several biotic and abiotic factors. Approximately 13 percent yield is reduced due to powdery mildew disease severity. In the present study, conducive environmental conditions for powdery mildew disease of Sunflower were characterized. All the environmental variables had significant correlate with powdery mildew disease severity. The data on epidemiological failures was analyzed through correlation and regression while the data on management was analyzed through Anova. The treatment means was compared through the help of LSD. Among the six Germplasm lines screened one line G12 was found moderate resistant against powdery mildew disease. Effect of different chemicals that include Topas, Clone, Aerosil, Kumulus and Sulfex Gold was determined in RCBD for controlling of powdery mildew disease of sunflower. In field evaluation of fungicides, three sprays of Kumulus at 0.02 per cent concentration were found superior.
