自1938年发现了滴滴涕的杀虫活性后,工业合成农药即化学农药驶入快车道。但是自上个世纪40年代至70年代,化学农药的严重毒害,如对环境及食品中的农药残留对人类潜在的慢性毒害;对非防治对象的影响和生态平衡的破坏;防治对象抗药性的发展,引起病虫害再度猖獗等问题,成为农药科学
Since the pesticidal activity of DDT was discovered in 1938, industrial synthetic pesticides, chemical pesticides, have been driven into the fast lane. However, since the 1940s to the 1970s, severe poisoning of chemical pesticides, such as potential chronic toxicity to humans by pesticide residues in the environment and foodstuffs, the impact on non-control subjects and the ecological balance, the prevention and treatment of drug-resistant Development, causing pests and diseases once again rampant and become a pesticide science
