摘要
乐果加ＨＰ－１对小麦蚜虫的室内联合毒力测定表明，ＨＰ－１对乐果具有较强的增效作用，最佳配比为９８∶２，以此比例配成的４０％渗乐乳油，对小麦蚜虫具有降低乐果用量５０％、防效好、成本低等优点。
Through the indoor toxicity tests of different proportions of dimethoate to HP-1, we found that HP-1 had obvious effect in improving the control of dimethoate on wheat aphid (Macrosiphum avenae Fabricius), and the optimun proportion was 98∶2; 40% high permeable Dimethoate (EC) had the best effect with other advantages like lessening the use of dimethoate by 50%, high control effect of wheat aphid and low cost.
