Abstract
Sustainable Strategies for Managing Bacterial Panicle Blight in Rice
Highlights
Bacterial panicle blight (BPB), caused primarily by Burkholderia glumae, has become a threat to rice production globally
In the disease-yield loss field study, we found BPB was highly destructive and could cause yield losses ranging from 1 to 59% (83–4883 kg/ha), with yield loss increasing approximately 5% (455 kg/ha) for every unit increase in BPB severity on the rating scale of 0–9 [12]
We focus on the review of recent advances on the development of management strategies for BPB, including exclusion, genetic resistance, chemical control, biological control, and cultural practice
Summary
Bacterial panicle blight (BPB), caused primarily by Burkholderia glumae, has become a threat to rice production globally. BPB has the potential to cause significant losses in grain yield and milling quality in epidemic years. In Texas, the outbreaks of BPB resulted in an estimate of 10–20% yield loss in the Texas Rice Belt in 2010 [10, 11]. Outbreaks of this disease occurred in rice under organic production systems in 2010 in Texas [11]. No chemical control options are available in the USA oxolinic acid has been used as a major control measure for BPB in Japan for more than two decades [15]. Resistant populations of B. glumae to oxolinic acid have been found [16–19], which limits increasing use of this antibiotic compound for management of BPB.
