化学除草剂对环境的污染及防治对策

Chemical Herbicide of Pesticides on Environment and Countermeasures for Prevention and Control

主要阐述了使用化学除草剂对大气、水质、土壤造成的环境污染,提出了加强除草剂的市场监管及农产品检测的对策:应选择高效、低毒、低残留的除草剂;加强除草剂管理及农产品检测工作,应用物理防治、生物防治、遗传育种等非化学防治手段提高对草害的综合防治,减少除草剂对环境的污染。

The paper mainly describes the environmental pollution such as,atmosphere,water quality and soilcaused by the use of chemical herbicides.It also proposes to strengthen the market supervision of herbicides and agricultural product testing.The selected pesticides should be chosenwith efficient,harmfulness andeasily degradable.The management of herbicidesand agricultural product testingshould be strengthened.Comprehensive prevention and control of weed damage can be improved to reduceenvironment pollution caused by pesticidesthroughnon-chemical control methods such as physical control,biological control,and genetic breeding.
