摘　　要：从西南地区云贵川3省分离得到水稻细菌性条斑病菌菌株43株,离体条件下检测菌株对申嗪霉素及噻唑锌的敏感性.结果表明：不同地理来源的菌株对两种药剂的敏感性均存在一定差异.噻唑锌及申嗪霉素对各地来源菌株的EC5o值的分布范围分别是0.439 ～2.549 μg·mL-1和0.035～ 1.598 μg·mL-1,平均值分别为1.641、0.868 μg·mL-1.初步确定将四川、贵州、云南3省菌株的EC50平均值1.641、0.868 μg· mL-1分别作为西南地区水稻细菌性条斑病菌对噻唑锌及申嗪霉素的敏感基线.The 43 strains of Xanthomonas oryzae pv.oryzicola from Yunnan,Guizhou and Sichuan provinces,and their sensitivities were examined to phenazino-1-carboxylic acid and zinc thiazole in vitro.The results showed that there were sensitivity differences among the strains.The EC50 values of phenazino-1-carboxylic acid and zinc thiazole to all tested strains ranged from 0.439-2.549 μg · mL-1 and 0.035-1.598 μg · mL-1 with the average of 1.641 μg · mL-1 and 0.868 μg · mL-1,respectively.The average EC50 1.641 μg · mL-1 and 0.868 μg · mL-1 was the baseline-sensitivity of Xanthomonas oryzae pv.oryzicola from Yunnan,Guizhou and Sichuan provinces to phenazino-1-carboxylic acid and zinc thiazole,respectively.
