Effect of Bioagent Application on Progress of Bacterial Leaf Blight of Rice, Under Glasshouse Conditions

Present study was carried out to evaluate different bioagent formulations against bacterial leaf blight disease of rice by using different epidemiological parameters and compared with check and chemical treatment, under glasshouse conditions. Disease progress curves were developed for different treatments and infection rate and area under disease progress curve was calculated. Disease progress curves of bacterial leaf blight disease revealed that bioagent formulations were found to be effective in reducing the progress of disease as compared to control. After 19 days of application, bioagents formulations were found to be significantly effective than chemical treatment in reducing progress of disease. Infection rate of disease recorded with bioagent formulations was lower than check and chemical treatment. Application of bioagents resulted significantly reduced the area under disease progress curve as compared to check and chemical treatment and increased grain yield was recorded.
