由于大量使用的一些传统农药存在毒性、环境安全性问题,另有不少品种虽然毒性较低,但由于害物抗性问题,也急需新的具有不同作用机理的药剂予以替代,因此开发新农药,尤其是作用机理不同、绿色环保的品种刻不容缓。在过去的几年,除草剂市场中增长较快的有唑啉草酯、敌草隆、烯草酮、甲基磺草酮、氟磺胺草醚以及在原有机理上性能有所改进或更环保的产品(酰胺类的双氟磺草胺、五氟磺草胺,吡啶类的氯氨吡啶酸、敌草快,磺酰脲类的甲基二磺隆,芳氧苯氧丙酸类的氟吡甲禾灵)。增速下滑的有毒性较大的酰胺类的乙草胺、二甲戊灵、吡氟酰草胺、二甲吩草 Due to the toxicity and environmental safety problems of some traditional pesticides used in great quantities, many other species, although less toxic, are in urgent need of new agents with different mechanism of action due to pest resistance. Therefore, the development of new pesticides In particular, different mechanisms of action, green varieties urgently. In the past few years, the more rapid growth of the pinoxaden, diuron, clethodim, mesotrione, fomesafen in the herbicide market has improved or is more environmentally friendly (Amoxicillins such as florasulam, penoxsulam, pyridine, pyrazolopyridines, diquat, metsulfuron-methylsulfonyl, sulfoxides such as fluorine Pycnogenol). Slower growth rate of the more toxic amide acetochlor, pendimethalin, diflufenican,
