从近30年农药用量谈如何正确看待农药

How to view pesticides correctly based on the pesticide dosage in the past 30 years

农药是一类特殊的商品,在农业生产中起着重要的作用。随着农药的多年使用,病虫草害抗药性、食品安全性、环境污染等问题成为人们议论的焦点,出现“发达国家农药使用量少”、“施用农药的农产品不安全”、“农药严重污染环境”、“让农药退出农业生产”等多种片面观点,针对这些观点,笔者分析了近30年世界农药年使用量及单位面积农药用量变化,将我国与发达国家(美国和日本)、发展中国家(巴西和阿根廷)进行对比分析,用科学的数据引导人们树立科学的农药使用观,正确看待农药发展。

Pesticide is a kind of special commodity,which plays an important role in agricultural production.With the use of pesticides for many years,problems such as resistance to diseases,pests and weeds,food safety,and environmental pollution have become the focus of discussion among people.There are many one-sided views such as‘less pesticides are used in developed countries’,‘agricultural products applied with pesticides are unsafe’,‘pesticides seriously pollute environment’and‘pesticides should withdraw from agricultural production’.This study analyzed the annual usage of pesticides and the changes of pesticide usage per unit area in the world in the past 30 years,compared China with the developed countries,the United States and Japan,and the developing countries,Brazil and Argentina,so as to guide people to establish a scientific view of pesticide use with scientific data and correctly view the development of pesticides.
