尽量降低苗前使用的除草剂及苗后使用的除草剂中有效成分的用量可减少对环境造成的压力,为此,制造商日益期待剂型改进。对表面活性剂和有效成分的叶面吸收之间的关系已给予了相当的重视。尽管助剂,尤其是聚氧乙烯类的非离子助剂的使用可以增加叶的吸收,但对其准确的作用位点和 Minimizing the amount of active ingredients used in herbicides and the herbicide used after emergence can reduce the environmental burden and manufacturers are increasingly looking for dosage forms to improve. The relationship between the surfactant and the foliar absorption of the active ingredient has received considerable attention. Although the use of auxiliaries, especially non-ionic polyoxyethylene-based auxiliaries, can increase leaf absorption, its exact site of action and
