A study on fungicides potential and incidence of sheath rot of rice in Eastern U.P


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

Abstract: Field experiments were conducted to determine the effects of planting date on incidence of rice stem borer in early, normal and late sown varieties of rice. Most popular rice variety Sambha Mahsuri were used. 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% @ 1.0ml/l., T2- Azoxystrobin 18.2% w/w SC @ 1.5 ml/l., T3- Azoxystrobin 11% w/w @ 1.5 ml/letter, T4- Tricyclazole 18% @ 1.5g/l., T5- Hexaconazole 4% WP @1.0 ml/l, T6- Trifloxystrobin 25% @ 0.5g/l., T7- Mancozeb 50% @ 1.5g/l., T8- Epoxiconazole 62.5 EC @ 1.5ml/l. and T9- Untreated control (Spray of plain water), were applied the recommended dose of each product to diseased plants at the rate of two sprays with an intravel of 15 days. Observations were recorded at 20 days after the second spray. Analysis of the data showed that among the treated with Trifloxystrobin 25% @ 0.5 g/l was found best in checking the disease severity of sheath rot (21.1%) and incidence was (70.0%) respectively and the better grain yield 5180 kg/ha was recorded. While severity and incidence of sheath rot had gone to the extent of 60.6 and 93.0% respectively in unsprayed plots. In check plots reduced grain yield was recorded (3144 kg/ha). In spite of increase in grain yield of treated with Trifloxystrobin 25% was 64.75 percent respectively followed by treated with Azoxystrobin 11% w/w disease severity of 22.9% and incidence of 74.0% while grain yield 4940 kg/ha.
