Assessment of integrated disease management for bacterial crown rot on rice

Abstract

Rice is an important staple food crop in India and it is being infected by many fungi, bacteria and viruses. Among these, bacterial crown rot caused by Erwinia spp. is an important disease of rabi rice in Nalgonda District Telangana.Keeping in view of threat and yield loss caused by this disease, KVK Kampasagar has identified bacterial crown rot as potential problem and conducted OFT trials with improved package of practices on farmer’s fields in Nalgonda District, Telangana. Based on the study, it is clearly evident that that adoption of recommended improved practices resulted in decreased disease incidence (11.1%), and increased grain yield (21.4%) compared to farmer’s practice. Similarly, lower cost of cultivation, higher the gross returns, net returns and benefit cost ratio were observed in improved practice over the farmers practice.
