Abstract:
Rice (Oryza sativa L.) is the most essential cereal crop consumed by 50% of world's population. An experiment was conducted during kharif 2016 to know the impact of ten treatments including fungicides, botanicals and bio-agents on management of blast of rice at AHRS, Ponnampet. Among ten treatments, Nativo was found effective in reducing both leaf blast (27.79 PDI) and neck blast (21.68%) disease. Tricyclazole + Tebuconazole 36% SC and ICF-110 were onpar with each other with respect to both leaf blast and neck blast incidence followed by Tricyclazole. Bacillus subtilis was found less effective in reducing both leaf and neck blast disease when compared to other treatments. The highest per cent disease reduction over control was found in Nativo with leaf blast (60.18%) and neck blast (59.00%). The least per cent disease reduction over control was recorded in Bacillus subtilis. Further, the highest yield was recorded in Nativo with 4204 kg/ ha. Followed by ICF-110 (3967 kg/ ha), Tricyclazole + Tebuconazole 36% SC (3806 kg/ ha), and Tricyclazole (3633 kg/ ha). The least grain yield was observed in Bacillus subtilis (2311 kg/ ha) when compared to other treatments.
