从上个世纪以来,农药的广泛使用减少了病虫害损失,但也严重地破坏了生态平衡,给人类带来无尽的烦恼。一方面,应用农药破坏了土壤中的微生物和低等动物的多样性,不利于控制有害生物和改善土质,其使用不当造成农产品减产、产品环境质量低劣;另一方面,由于许多作物(尤其是蔬菜和瓜果)收获季节最易发生病虫害,农民很难严格遵守农药使用间隔期规定,往往造成农产品农药残留问题,甚至出现中毒事件。在质量和数量、产品和病虫害的两难选择下,传统的植保体系显得步履维艰。这种状况的根源在于传统植保体系的根本思路;农业植保的主要目标就是 Since the last century, the widespread use of pesticides has reduced the loss of pests and diseases, but has also seriously damaged the ecological balance and brought endless troubles to mankind.
