Abstract

Bacterial panicle blight is the most devastating disease of rice caused by Burkholderia glumae. A study was conducted in taking 23 different antibiotics against B. glumae by using inhibition zone technique. Among twenty three antibiotics Rifampicin, Levofloxacin, Tetracycline, Cefotaxime, Azithromycin, Erythromycin, Clarthromycin expressed best result by producing 5.0 mean inhibition zone. The minimum zone of inhibition was recorded by Cefixim and Penicllin - G i.e. 1.1 mm after 48 hours

Keywords

Bacterial Panicle Blight, Burkholderia glumae, antibiotics, zone of inhibition

Conclusion

In comparison with other plant pathogenic bacteria, a little research has been done on Burkholderia glumae causing bacterial panicle blight of rice. The lack of approved and effective chemicals to control this disease makes bacterial panicle blight challenging to manage. In the present study, out of twenty three antibiotics Rifampicin, Levofloxacin, Tetracycline, Cefotaxime, Azithromycin, Erythromycin and Clarthromycin were found effective against Burkholderia glumae. Although Streptocycline is widely used in agricultural fields against most of the bacterial pathogens still we should be ready with other antibiotics and chemicals to manage such emerging plant pathogens
