【摘要】 农田杂草严重影响作物的产量和品质,对除草剂的过度依赖和长期使用,使杂草对除草剂的抗性问题日益突出。目前已有262种杂草(152种双子叶和110种单子叶)的512个生物型对23类中的167个除草剂产生抗性。激素类除草剂作为除草剂的重要成员,为禾谷类作物田的杂草防除提供了保障,然而在使用了几十年后,44种杂草对此类除草剂产生了抗药性。本文对激素类除草剂的分类应用、除草机理、抗性现状、抗性机理等进行了综述,以期为激素类除草剂的应用和抗激素类除草剂杂草的防除提供参考。更多还原

【Abstract】 Weeds in farmlands seriously affect the yield and quality of crops, and the weed resistance has become a serious problem due to prolonged use and over-reliance on limited herbicides. At present, 512 biotypes of 262 weeds(152 dicots and 110 monocots) have evolved resistance to 167 herbicides with 23 different sites of action. Auxin herbicides, as one of the important herbicides, provide a critical tool for weed control in cereal crops. However, 44 weed species have developed resistance to them after decades of continuous use. In this paper, the classification and application, weed control mechanism, resistance status and resistance mechanism on auxin herbicides were systematically summarized, in order to provide a reference for the application of auxin herbicides and control of resistant weeds.更多还原
