众所周知,化学农药是用来杀虫、治病和除草的。当从外地引进或合成一种新农药的时候,首先必须进行田间小区试验,然后才能够应用到大田生产上去。如何确定药效的好坏?要根据农药、生物和环境三个因素设置田间小区试验,再根据试验所得到的数据,进行正确的分析和比较之后方能对该农药的好坏下结论。作者根据工作实践和参考一些文献,就刺吸式口器害虫药效试验的计算方法,提出一些计算公式,供参考:
As we all know, chemical pesticides are used to kill insects, cure and weed. When introducing or synthesizing a new pesticide from the field, it is first necessary to conduct a field plot test before it can be applied to field production. How to determine the efficacy of good or bad? According to pesticides, biological and environmental factors to set three field plot test, and then based on experimental data obtained after the correct analysis and comparison before the pesticide can be concluded under the good or bad. According to the work practice and reference to some literatures, the author puts forward some formulas for calculating the efficacy test of sucking mouthparts pests, for reference:
