抗药性杂草对农田杂草治理和农业生产构成严重威胁,成为备受全球关注的严重问题。随着长期、大量使用相对有限的化学除草剂,全球抗药性杂草发展迅猛,目前已有217种杂草对化学除草剂产生了抗药性,我国抗药性杂草发展也十分迅猛。本文在介绍杂草抗药性基本概念、抗药性杂草发展过程、抗药性杂草现状的基础上,重点描述了抗药性杂草治理策略,以期为我国抗药性杂草研究和治理提供参考。
Resistant weeds pose a serious threat to farmland weed management and agricultural production and have become a serious issue of much global concern. With long-term, large-scale use of relatively limited chemical herbicides, global resistant weeds have developed rapidly. At present, 217 weeds have become resistant to chemical herbicides and the development of resistant weeds in China has also been very rapid. Based on the introduction of the basic concept of weed resistance, the development of resistant weeds and the current status of resistant weeds, this paper focuses on the strategy of resistance weed management, in order to provide a reference for the research and management of resistant weeds in our country.
