当前我国农药使用过程中主要存在用量大、使用不规范、利用率低等三大问题。我国农药使用量占世界总用量的1/7,利用率不足1/3,大量农药通过径流、渗漏、漂移等污染了土壤和水体,对农业生产环境造成严重影响,危及农产品质量安全。正确合理施用农药势在必行。另一方面,近年来农药种类、剂型发展迅速,农药市场鱼龙混杂、农药品种良莠不齐,给农民群众购买农药带来不少困难。 At present, there are three major problems in the use of pesticides in China, such as large dosage, non-standard use and low utilization rate. The pesticide usage in China accounts for 1/7 of the world’s total consumption and the utilization rate is less than 1/3. A large number of pesticides pollute the soil and water through runoff, seepage and drift, which seriously affect the agricultural production environment and endanger the quality and safety of agricultural products. Correct and reasonable pesticide application is imperative. On the other hand, in recent years, the types and formulations of pesticides have developed rapidly. The pesticide market is quite different. Pesticide varieties are mixed with each other, causing many difficulties for farmers to purchase pesticides.
