摘　　要：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。Chemical pesticides have always been the most effective, economical, simple and convenient methods, and are widely used in many areas without other restrictiveness since their emerging. The current state of the environment and the implementing of green chemistry are presenting a serious challenge to chemical pesticides, and yet at the same time, an opportunity for their development. The future direction of chemical pesticide development will be green pesticides that are chemically synthesized, termed as ＂green pesticides＂, their characteristics include 1） extremely high activity with low dosage and rapid efficacy, 2） high selectivity with effects only on harmful organisms, 3） non-pollution, either being nontoxic or having low toxicity, and rapid degradation.
