Review on Bacterial Blight of rice caused by Xanthomonas oryzae pv. oryzae: different management approaches and role of Pseudomonas fluorescens as a potential biocontrol agent

Abstract

Bacterial blight is a destructive disease of rice causes 20-50% yield losses in conducive conditions. In this paper a review on the occurrence and spread of the disease, about the pathogen, its races and strains, its survival, mode of infection and transmission, different management approaches and potential role of P. fluorescens in suppression of the pathogen has been carried out. From the laboratory and field assays it is evidenced that P. fluorescens is an effective bioagent against X. oryzae pv. oryzae. The integration of micronutrient with P. fluorescens has also been view in this chapter to find out the role of micronutrients in enhancing the aggressiveness of bioagent.
