Abstract
An experiment was conducted to study the efficacy of fungicides and bioagents against powdery mildew (Erysiphe polygoni DC.) in the experimental field of Department of Plant Protection, Sam Higginbottom Institute of Agriculture, Technology and Sciences, Allahabad in Rabi Season of 2013- 2014. Seven treatment including control with three replications were taken up using RBD. Treatments of foliar spray of Tilt 25% EC (propiconazole ) 50% WP (carbendazim), 0.05%, Bavistin @ 0.1%, Trichoderma viride 10g / lit, Trichoderma harzianum 10g/lit. Pseudomonas fluorescence 10g/lit and control were applied at the onset of disease symptoms at 125 DAS. Per cent disease intensity was recorded at 10 and 20 days after spray. Minimum disease intensity was recorded in at 10 days and 20 days after the spray carbendazim (11.93% and 15.25% ) followed by propiconazole (15.08% and 16.83), Trichoderma harzianum (15.95% and 21.01%), respectively.
