Management of Bacterial Blight of Clusterbean Caused by Xanthomonas axonopodis pv. cyamopsidis under Field Conditions

Background: Bacterial blight pathogen (Xanthomonas axonopodis pv. cyamopsidis) of clusterbean causes considerable damage every year during Kharif season and sometimes become very severe, which results in heavy loss grain yield. Methods: On the basis vitro studies, most effective botanical, antibiotic fungicide at highest concentration were used as individual its combinations field experiment two consecutive years 2018 2019. Seeds cultivar RGC-936 artificially inoculated with X. cyamopsidis by soaking bacterial cell suspension (2.5x108 cfu/ml) for 30 min dried under shade. The seeds sowing trial Result: Field evaluation, combined treatment, seed treatment streptocycline @ 250 ppm followed foliar sprays 1st spray copper oxychloride 0.3 per cent 2nd 15 days interval was found reducing disease severity increasing fodder yield clusterbean.
