Abstract
Rice blast caused by Pyricularia oryzae, Cav. is one of the major disease of rice and cause approximately 45-50 % yield losses. The present study was conducted at the experimental field of Krishi Vigyan Kendra Majhgawan, Satna (M.P.) during Kharif season of 2017-18 to know the efficacy of different foliar fungicides against blast disease of rice. Seven treatments including control with three replications were taken up by using RBD. The fungicides viz., azoxystrobin 18.2 % + difenoconazole 11.4 % (Amistar top 29.6 % SC) @ 0.13 % (T1), tebuconazole 50 % + trifloxystrobin 25 % (Nativo 75 % WG) @ 0.07 % (T2), carbendazim 12 % + mancozeb 63 % (Saaf 75 % WP) @ 0.2 % (T3), tebuconazole 25.9 % (Folicur 250 % EC) @ 0.2 % (T4), hexaconazole 5 % (Contaf plus 5 % SC) @ 0.2 % (T5), difenoconazole (Score 250 % EC) @ 0.06 % (T6) and control (Spray of plain water)- T7, were applied first at just after occurrence of disease symptoms and second at 15 days after the first spray. Observations were recorded at 10 days after the second spray. Analysis of the data showed that among the six fungicides, the minimum disease per cent intensity was recorded in T2 i.e. tebuconazole 50 % + trifloxystrobin 25 % (WG) 11.46 per cent, followed by T1 i.e. azoxystrobin 18.2 % + difenoconazole 11.4 % (SC) with 12.85 per cent, respectively. The highest per cent disease intensity of 69.40 per cent was observed in Control (Spray of normal water) treatment. Significantly highest grain yield was recorded in tebuconazole + trifloxystrobin 75 % (WG) sprayed treatment i.e. (4102.11 kg/ha), followed by azoxystrobin + difenoconazole 29.6 % (SC) (3967.28 kg/ha) and the lowest yield of 2116.23 kg/ha was recorded with untreated control.
