为在防治农作物病虫害方面达到合理、经济、有效地使用农药,近年来在群众性科学实验活动中,对试验有效低浓度的用药方法已取得显著成效。农药低浓度能一举五得:省农药、省成本、残毒少、杀伤天敌少、药害少,使农药用得更科学合理。所以在防治病虫害采用有效低浓度的用药办法是植保工作的一项极为重要的措施。根据试验单位的实践,推广农药有效低浓度要注意以下几点:
In order to achieve the rational, economical and effective use of pesticides in the prevention and control of plant diseases and insect pests, in recent years, mass effective scientific experiments have yielded significant results in the test of effective low-concentration drug use. Low concentrations of pesticides can do well in one fell swoop: Provincial pesticides, provincial costs, less residuals, fewer natural enemies, less phytotoxicity, pesticide use more scientific and rational. Therefore, the use of effective low concentrations of pesticides in the control of pests and diseases is a very important measure for plant protection work. According to the practice of experimental units, to promote the effective low concentration of pesticides should pay attention to the following points:
