Abstract:
The biocontrol agents and fungicides were evaluated in the field, against sheath rot disease of rice in kharif 2022 at RRS, Moncompu. Management of disease before panicle emergence is very much essential. Prophylactic application of talc-based formulation of Bacillus sp. B15, Bacillus sp. B17, Bacillus sp. B33, Bacillus sp., B42 B 15+ B 17+ B 33+ B 42 consortium and Pseudomonas fluorescens (PN026) as seed treatment (10g kg- 1) + soil application (1kg/acre) + foliar spray (20g L-1 of water at booting) for the management of sheath rot disease of rice and thereby improving the yield. Among all the bioagent treatments, the application of B 15+ B 17+ B 33+ B 42 consortium shows more efficacy for the management of sheath rot disease of rice and improving the yield.

Among all the bioagent treatments, the application of B 15+ B 17+ B 33+ B 42 consortium shows more efficacy for the management of sheath rot disease of rice and improving the yield.
Four commercial fungicides viz., Copper hydroxide 77 WP @ 2 g L-1, Trifloxystrobin 25%+Tebuconazole 50% 75 WG @ 0.4 g L-1, Propineb 50 WP @ 2.5 g L-1 and Hexaconazole 5 EC@2 ml L-1 were given as foliar spraying at booting stage. Among the all the fungicides tested in the field, Trifloxystrobin 25%+Tebuconazole 50% 75 WG @ 0.4 g L-1 and Hexaconazole 5 EC@ 2 ml L-1 applied as foliar spraying were found significantly superior in reducing the disease and increasing the yield followed by Propineb 50 WP @ 2.5 g L-1 and Copper hydroxide 77 WP @ 2 g L-1. Benefit cost ratio is also more in case of B 15+ B 17+ B 33+ B 42 consortium and Trifloxystrobin 25%+Tebuconazole 50% 75 WG @ 0.4 g L-1.
