Effect of different fungicides on Karnal Bunt (Tilletia Indica Mitra (Syn. Neovossia Indica) disease of wheat in Uttar Pradesh

Abstract

Experiments were conducted at during Kharif 2017-18 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, to evaluate the compatibility of fungicidal evaluation against Karnal Bunt disease of Uttar Pradesh The karnal bunt causing major loss of wheat production. The experiment consisted of nine treatments viz. T1Carbendazim 50 WP @ 2.5g/l., T2- Vitavax 75WP @ 2.0g/l., T3- Propiconozole 20 EC @ 1.0 ml/letter, T4- Azoxystrobin 18.2 % w/w @ 1.0ml/l., T5- Tricyclazole 18 % w/w @ 2.5g/l, T6- Flusilazole 12.5%w/w @ 1.0ml/l., T7- Tebuconazole 50% WG @ 1.0ml/l., T8- Hexaconazole 4%WP @ 2.5g/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 Tricyclazole 18 % w/w @ 2.5 g/l was found best in checking the disease severity karnal bunt (13.2%) and incidence was (11.6%) respectively and the better grain yield 3733 kg/ha was recorded. While severity and incidence of karnal bunt had gone to the extent of 42.7 and 38.7 % respectively in unsprayed plots. In check plots reduced grain yield was recorded (1967 kg/ha). In spite of increase in grain yield of treated with Tricyclazole 18 % w/w was 89.78 percent respectively, followed by treated with Tebuconazole 50% WG was severity and incidence of karnal bunt 13.6 and 12.6% and grain yield was 3600 kg/ha, increase 83.01, over check minimization of disease severity.
