摘要：

Four antagonists, viz., Bacillus sp., B. subtilis, 1213, and Pseudomonas fluorescens which were inhibitory towards bacterial blight of cotton (Xanthomonas axonopodis pv. malvacearum) in vitro were found to exert different mechanisms of biological control. All the antagonists produced antibacterial metabolites. Psuedomonas fluorescens and 12D produced siderophores and hydrocyanic acid. For the pathogen, low pH (5.5) was unfavourable and Bacillus sp. and 12D lowered the pH of the growth medium.
