农药对保护植物免遭病、虫、草害,对各种作物正常生长,增加产量具有很重要的作用;农药施用后能否得到应有效果,这与农药的质量有密切的关系。在农药应用中有很多实例证明施用同一种农药,由于质量不同,而防治效果有很大差异。过去,我国生产厂对农药的质量一直很重视,严格检验产品,注意不断提高质量。后来,由于“四人帮”的干扰破坏,农药管理机构被撤销,有关农药质量的管理办法被废除,因而农药生产不受约束,产品质量不断下降,农药质量几乎处于无人过问状态。同时,收购部门也放 Pesticides play an important role in protecting plants from diseases, insects and weeds, and have a very important effect on the normal growth and yield of various crops.
