A field experiment was conducted to evaluate the efficacy of fungicides against Field pea 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 2012-2013. Treatments of foliar spray of Tilt 25% EC (propiconazole ) @ 0.1%, Contaf 5% EC (hexaconazole) @ 0.05%, Bavistin 50% WP (carbendazim), Kavach 75% WP (chlorothalonil), Sulfex 80% WP (wettable sulphur), Indofil 75% WP (mancozeb) and control (spray of plain water) were applied at the onset of disease. Minimum disease severity was recorded in propiconazole (11.40 % and 14.96 % at 10 and 20 days after spray respectively) followed by hexaconazole (15.77 % and 16.09 % at 10 and 20 days after spray respectively) and significantly maximum disease intensity was observed in mancozeb (17.33 % and 22.81 % at 10 and 20 days after spray respectively) as compare to control.
