Abstract

In the present study, effectiveness of different fungal (Trichoderma harzianum) and bacterial (Pseudomonas fluorescens) bioagent formulations in reducing progress of the bacterial leaf blight disease of rice under field conditions was studied and compared with chemical treatment and untreated check. The results exhibited that after 23 to 30 days after first application, bioagent formulations were more effective then chemical treatment in reducing progress of disease. Bioagent formulations exhibited long lasting effect in reducing progress of disease during Kharif, 2006 and 2007. Application of bioagent formulations resulted in significant reduction (60.5 – 142.8%) in area under disease progress curve (AUDPC) as compared to check during Kharif, 2006 and 2007. Significant increase in grain yield (14.3 - 21.5 %) was observed with the application of bioagent formulations as compared to check during Kharif, 2006 and 2007.
