1992-1994年对海南、广东两省5个地区的香蕉潜伏炭疽菌的抗药性进行研究。结果表明,直接从田间幼果分离获得的5号芭蕉炭疽菌系,对多菌灵敏感,均未表现出抗药性,而且5号菌系之间的敏感性及致病性差异不显著。采用多菌灵药剂连续刺激诱导44代后,5号菌系的EC50值均有提高,产生了不同程度的抗药性,但表现不一;其中以琼山菌系变化最显著,R/S值超过4倍以上,并且琼山菌系的致病力较用药刺激前低。
1992-1994 on Hainan, Guangdong Province, five areas of banana latent anthrax drug resistance study. The results showed that the anthrax strain No. 5 isolated from the field young fruit was sensitive to carbendazim and showed no resistance. The sensitivity and pathogenicity of the strain No.5 were not significantly different. The EC50 values of strain 5 increased after 44 generations of continuous stimulation with carbendazim, which led to different degrees of resistance, but the performance was different. Among them, the most significant change was in the genus Qingshan, and the R / S value More than 4 times, and the pathogenicity of Qiongus strains was lower than that before drug stimulation.
