化学农药自产生以来,一直是农业有害生物防治最有效、最经济、最简便、最能普遍应用、不受地区性和其它限制的方法。环境的现状和绿色化学的实施对化学农药提出了挑战,同时也为化学农药的发展提供了机遇。今后化学农药的发展方向是化学合成类绿色农药,即绿色化学农药,其特点是:①超高效:用药量少而见效快;②高选择性:仅对特定有害生物起作用;③无公害:无毒或低毒且能迅速降解。 Since its production, chemical pesticides have been the most effective, economical, easiest, most universal and most universal method of agricultural pest control, regardless of the regional and other restrictions. The status quo of the environment and the implementation of green chemistry have posed challenges to chemical pesticides and also provided opportunities for the development of chemical pesticides. The future direction of chemical pesticides is chemical synthesis of green pesticides, green chemical pesticides, which are characterized by: ① ultra-efficient: less dosage and quick; ② high selectivity: only for specific pests play; ③ pollution-free: Non-toxic or low toxicity and rapid degradation.
