Bacterial panicle blight caused by Burkholderia glumae: a major disease in rice cultivation

Abstract

Rice, as one of the most important agricultural commodities, encounters numerous challenges throughout its cultivation in the field. One significant challenge arises from the manifestation of diseases, which can severely reduce yields. Bacterial panicle blight, primarily caused by Burkholderia glumae, is a significant threat to global rice production. This disease is highly destructive, directly impacting yield and production. In recent years, multiple reports have highlighted a global increase in bacterial panicle blight associated with B. glumae. Hence, this article offers a comprehensive summary of bacterial panicle blight diseases occurring worldwide. Additionally, we examined the incidence of B. glumae-panicle blight disease, the characteristics of B. glumae, its symptoms and epidemiology, its disease cycle, and effective control measures to combat both the disease and the pathogen. A comprehensive understanding of this disease will enhance our knowledge of how to mitigate the impact of this destructive disease on rice productivity worldwide.
