Field experiment was conducted at All India Coordinated Rice Improvement Project (AICRIP), RRTTS, Chiplima during kharif season of 2014 and 2015 to find out the efficacy of disease management practices against leaf blast disease of rice and their interaction with regard to varietal resistance. The experiment was laid out in split plot design having three varieties in main plot and two management levels in sub plot. The result revealed that the disease pressure remained low in both moderately resistant and hybrid variety as compared to the susceptible variety in all the plots irrespective of management practices. In case of moderately resistant and hybrid variety, a single spray of tricyclazole @ 0.6 g/l was sufficient to minimize the disease below ETL level where as in case of susceptible variety, disease pressure was high and three spraying of tricyclazole @ 0.6 g/l were required to check the disease (7.33 % severity) as compared to control plots with 28.65 % disease severity. The present study ascertains the response of resistant as well as the hybrid variety to effective dose of nitrogen (2/3rd of the recommended dose applied in 3 splits), seed treatment (carbendazim @ 2g/kg seed), line transplanting, FYM application (10 t/ha) and a single fungicidal spray (tricyclazole @ 0.6 g/l) as an effort to manage the leaf blast disease in an integrated way.
