中文摘要：

化学农药作为防治有害生物的一种有效手段，在作物生产巾起到重要作用。但是它在常用剂量下对作物造成的影响并未受到足够的重视。综述了化学农药对作物光合作用、主要营养物质、次生物质及次生代谢、活性氧代谢、体内酶的变化、根系活力及生长调节物质等主要生理生化指标的影响。提倡应用IPM措施进行治理。

英文摘要：

Chemical pesticides are an effective method for controlling destructive biological agents, and are important in crop production. However, inadequate attention has been given to the effects these pesticides have on crops, even when applied at commonly used rates. This paper summarizes the effects of chemical pesticides on the main physiological and biochemical indices such as photosynthesis, primary nutrients, secondary substances, secondary metabolism, active oxygen metabolism, changes in enzyme content, root system vitality, and growth regulating substances. IPM programs are advocated for pest management.
