在第八届全国农药登记评审委员会第十次全体上,专家建议应当在我国停止使用甲磺隆、氯磺隆、胺苯磺隆、氯嘧磺隆等除草剂。据调查,这些除草剂残效期长,易对后茬作物产生药害。而国外有些国家因耕作制度不同,有的休耕期较长,使用药害风险小,因而有一定的市场需求。 At the 10th National Committee of the Eighth National Pesticide Registration and Accreditation Committee, experts suggested that we should stop using the herbicides such as metsulfuron-methyl, chlorsulfuron, triasulfuron, and chlorimuron-ethyl in our country. According to the survey, these herbicides have long residual effects and are apt to cause phytotoxicity to the crops afterwards. In some countries abroad, due to different farming systems, some have a long period of fallow, and the risk of using phytotoxicity is small, so there is a certain market demand.
