Powdery mildew of chilli incited by Leveillula taurica (Lev.) Arn. is a devastating disease of chilli. In the present investigation, management of Powdery mildew disease was undertaken during 2015-16 by the application of fungicides, bioagents and botanicals under field conditions. Among the twelve treatments, Myclobutanil (0.1 %) spray was found most effective in reducing the disease severity (PDI 17.37) followed by Triadimefon (PDI 20.70) and Hexaconazole (PDI 23.75) compared to control (PDI 88.24) respectively. The bioagents, Pseudomonas fluorescens (PDI 61.14) and Trichoderma harzianum (PDI 63.79) and the plant extracts viz., Azardiracta indica (PDI 62.56) and Allium sativa L. (PDI 63.54) were found less effective in reducing the disease severity as compared to fungicidal treatments respectively. Further, Myclobutanil and Triadimefon recorded higher dry chilli yield of 12.72 and12.27 q/ha. The highest cost: benefit ratio was obtained in Myclobutanil (1:2.43) sprayed plots followed by Triadimefon (1:2.39) respectively.
