Abstract

A survey was conducted on aromatic rice during the kharif seasons of 2019 and 2020 in the five valley districts of Kakching, Thoubal, Bishnupur, Imphal-East, and Imphal-West, Manipur to assess the natural disease occurrence of blast, brown spot and sheath blight diseases. The survey revealed that disease incidence and severity varied with locations. Blast, brown spot, and sheath blight have an overall disease incidence of 36.94%, 37.15%, and 37.34%, respectively, and severity of 34.62%, 31.28%, and 36.92%, respectively. Of the five valleys surveyed, Imphal East recorded the maximum mean incidence (41.80%) and severity (39.61%) of blast and Bishnupur recorded the maximum mean incidence (39.53%) and severity (34.90%) of brown spot disease. However, sheath blight incidence was higher in Imphal East valley (39.0%) and its severity was higher in Bishnupur (39.61%). The current research could pave the way for future management measures against the specific disease and an efficient, coordinated approach to the sustainable development of crops in the state.
