Abstract
Bacterial leaf blight (BLB) of rice, caused by Xanthomonas oryzae pv. oryzae, represents a significant phytopathological challenge affecting rice crop. The present investigation aimed to investigate the effectiveness of integrated disease management (IDM) in reducing the bacterial leaf blight incidence in rice and improving the crop economics thereby as compared to those under conventional and chemical control practices. Field trials were conducted in Mirzapur district, India, with three treatments: T1 (conventional control), T2 (chemical control) and T3 (IDM). It was found that IDM significantly reduced BLB incidence (7.81%) compared to the other treatments (18.0% and 11.21% under T1 and T2, respectively). Crop yield was highest in the IDM treatment, followed by the chemical control and conventional control treatments. IDM also yielded in the highest net return and benefit-cost ratio, indicating its economic viability. These findings suggest that IDM is an effective and sustainable approach for managing BLB and improving rice production.
