Efficacy of Novel Fungicides for the Management of Sheath Blight of Rice Caused by Rhizoctonia solani (Kuhn)

In the present studies eight fungicides were evaluated against the sheath blight disease of rice during Kharif-2021-23. Among the different fungicides evaluated, two sprays of azoxystrobin 18.2 + difenoconazole 11.4 (29.6 SC) at 0.03 per cent (10 ml/10 l. water) or trifloxystrobin 25 + tebuconazole 50 (75 WG), 0.03 per cent (04g/10 l.water) for effective management of sheath blight. First spray should be applied at appearance of disease and second spray at booting stage. PHI 31 days for azoxystrobin 18.2 + difenoconazole 11.4 (29.6 SC) or 21 days for trifloxystrobin 25 + tebuconazole 50 (75 WG). The other effective fungicides were viz., fluxapyroxad 62.5g/l FS + epoxiconazole 62.5 g/L EC, tebuconazole 25.9 EC, Flusilazole 12.5 + carbendazim 25 (37.5 SE), Kresoxim methyl 44.3 SC, Zineb 68 + hexaconazole 4 (72 WP) and Propiconazole 25 EC.
