Evaluation of fungicides management of powdery mildew (Erysiphe Polygoni DC) disease of field pea (Pisum Sativum L.) in Eastern U.P.


Author(s): Uday Partap Singh and Dr. Chandra Shekhar

Abstract: The experiment was conducted to find out the efficacy of some new fungicides against powdery mildew (Erysiphe polygoni DC.) in the experimental field of experiment was laid out during rabi 2018-19 at supervision of Asha Bhagwan Bax Singh P.G. College Ayodhya, in the 7 farmer's field of Ayodhya and Ambedkarnager district of Uttar Pradesh. The experiment consisted of nine treatments viz. T1- Flusilazole 12.5% @ 1.0 ml/l., T2- Azoxystrobin 18.2 % w/w % @ 1.0 ml/l., T3- Tricyclazole 18 % @ 1.5 g/letter, T4- Propiconazole @ 1.0 ml/l., T5- Trifloxystrobin 25% @ 1.0 g/l, T6- Difenoconazole 11.4 % w/w SC @ 1.0 ml/l., T7- Mancozeb 50% @ 1.5 g/l., T8- Hexaconazole 4%WP @ 1.5 g/l.and T9- Untreated control (Spray of plain water), were applied the recommended dose of each product, were applied at the onset of disease. Minimum disease severity was recorded in propiconazole (8.58 % and 10.12 % at 10 and 20 days after spray respectively) followed by Azoxystrobin 18.2 % w/w (9.33 % and 11.17 % at 10 and 20 days after spray respectively) and significantly maximum disease intensity was observed in mancozeb (26.28 % and 29.13 % at 10 and 20 days after spray respectively) as compare to control (31.10 & 38.80%). The maximum pod yield of treated with propiconazole 11.13 t/ha increase over control 114.03% followed by Azoxystrobin 18.2 % w/w 10.18t/ha respectively.
