 ABSTRACT

Powdery mildew of chilli incited by Leveillula taurica was found to be one of the devasting disease of chilli. Differential set of fungicidal sprays of sulphur 80WP (0.3%) were given to estimate yield loss due to chilli powdery mildew. Results revealed that, three sprays of Sulphur 80 WP (0.3 %) at 12 days interval starting from the appearance of disease was optimum in reducing the disease with least per cent disease index and increasing the yield of 9.54 q/ha and cost benefit ratio of 1:3.03. Yield loss of 50 per cent was noticed due to powdery mildew in unsprayed control.

Key words: Leveillula taurica, Powdery mildew, Sulphur, Per cent disease index
