摘要
用杀虫双对草坪中的优势害虫二化螟做防治试验,测得ED50为0 0507g m2,ED95为0 111g m2,根据用药浓度与防治效果的对应关系,绘制出了防效与适宜用药量模拟图,旨在探索草坪二化螟防治的理论和技术,提高草坪管理的技术含量。
A trial was conducted using Sha chong shuang to control the dominant pest in lawns, namely the striped rice borer (Chilo suppressalis), with the following results: ED50=00507g/m2 and ED95=0111g/m2 According to the corresponding relationship between medicine concentration and control result, a simulation figure is drawn out on the control result and suitable quantity of medicine
