自1992年首先在浙江发现对多菌灵杀菌剂产生抗药性的小麦赤霉病病菌以来,抗药性病菌迅速扩散蔓延,目前已蔓延到上海和江苏全境,并很可能已蔓延至华东各省。这将使中国目前惟一的用多菌灵等苯并咪唑类菌剂防治小麦赤霉病的手段完全失效。专家称,以后一旦遇到多雨年份,华东地区小麦赤霉病将无法控制。目前中国小麦赤霉病防治技术单一。国内自
Since the first discovery of a pathogen of Fusarium head blight resistant to carbendazim in Zhejiang in 1992, the rapid spread of drug-resistant bacteria has now spread to Shanghai and Jiangsu and is likely to have spread to all eastern provinces. This will completely invalidate the only means of combating wheat scab in China with benzimidazole bacteriocides such as carbendazim. Experts say that in the future when rainy days are encountered, head blight in East China will not be able to control it. At present, the technology of wheat scab in China is single. Domestic since
