Abstract
On farm trial was conducted in farmers fields to evaluate the efficacy of integrated disease management (IDM) against sheath blight in paddy. The results revealed that, the per cent disease incidence of sheath blight in IDM, chemical-based management and farmers practice was 11.14, 19.9 and 26.2 per cent, respectively with per cent reduction of 57.4 and 24.1 per cent over farmers’ practice. With respect to per cent disease severity, it was 13.8, 19.1 and 28.4 per cent in IDM treated plot, chemical based management plot and farmers practice with 51.4 and 32.7 per cent reduction over farmers practice. Adoption of integrated disease management (IDM) practices had significantly reduced sheath blight incidence by 57.4 per cent and disease severity by 51.4 per cent.
