吡虫啉与几种常用农药混用对稻飞虱的综合防治效果

Intergrated Control Efficacy of BinaryMixture of Imidacloprid and Some Common Insectcides against Rice Planthoppers

吡虫啉是浙江省仙居县用于防治白背稻虱、灰稻虱的首选药剂,很少单独使用。笔者研究了吡虫啉与6种常用药剂混用对这两种飞虱的综合防治效果,结果表明,各处理均有不同程度的增效作用或叠加防治效果,其用量可减少25%～50%,尤以与杀虫单、杀虫双混用增效作用最显著。

Imidacloprid is a very important insecticide in the control of Sogatella fureifera （Horv6th） and S. striatellus （Fallen）. The preventing and controlling effect of the mixture of imidacloprid with 6 commonly used agrochemicals on these two kinds of planthopper was studied, and the result indicated that each processing had different degree efficiency or superimposition preventing and controlling effect, the amount of imidacloprid could be reduced by 25%-50%. The most remarkable efficiency was obtained when Imidacloprid mixed with monosultap or disinfestation.
