针对目前农林生产病虫草农药施用中存在的问题,笔者分析了其原因,提出了相对应的防控措施。
How to make pesticides and biocides application more effective？ In our opinion, there are three major problems： Firstly, most pesticide application equipments are old, out of date and cannot provide good dispersion and spreading of pesticides; Secondly, those equipments are not operated with care or by experienced operators and thus pesticides are not applied on part of plants at all, or not applied evenly, or not in sufficient amount; Thirdly, the effect of pesticides are highly affected by temperature, wind and other conditions while being applied.
