建国以来,化学农药的发展异常迅速,在农业生产上起了很大作用。近几年由于有机磷制剂的推广应用,有些地区对六六六、滴滴涕、赛力散等农药认为是“老药”,不顾使用;同时,对积存时间较长的药剂,认为已经失效,要求报废。 Since the founding of the People’s Republic of China, the development of chemical pesticides has been unusually rapid and has played a significant role in agricultural production. In recent years, due to the popularization and application of organophosphorus preparations, some regions regard pesticides such as BHC, DDT and racemic powder as “old drugs” irrespective of their use. In the meantime, those pesticides that have been stored for a longer period of time are considered ineffective and require scrapped.
