tailieunhanh - Antibacterial activity of antagonists, botanical and chemical against Pantoea stewartii sub sp. indolegenes causing bacterial leaf blight of rice

Rice is one of the important cereal crop and known to be affected by many diseases. Bacterial leaf blight of rice is a destructive disease of rice, known to be caused by Xanthomonas oryzae pv. oryzae and it also be reported to cause by species of Pantoea. BLB diseased samples were collected from southern districts of Tamil Nadu and upon isolation, the pathogen was thought to be Xanthomonas oryzae pv. oryzae. But, the results of biochemical and molecular characterization revealed that the causal agent was not Xanthomonas, but a new species of bacterium Pantoea stewartii subsp. Indolegenes (Accession No. SUB2733370: MF163273; MF163274; MF16327). The present study was conducted to investigate the antibacterial activity of different botanicals, antagonists, chemicals and antibiotics on the growth of Pantoea. In vitro studies revealed, the extract of Prosopis () was proved to having anti-bacterial activity at 10 per cent and Bacillus subtilis () was the potent antagonist. The evaluation of different fungicides and antibiotics revealed that copper oxy chloride ()and streptomycin () having maximum inhibitory effect on Pantoea. | Antibacterial activity of antagonists, botanical and chemical against Pantoea stewartii sub sp. indolegenes causing bacterial leaf blight of rice
