为探明螺虫乙酯与乙螨唑两者之间混配对柑橘红蜘蛛(柑橘全爪螨)联合作用的最佳配比,江西农业大学和清远市清新区敬农农业服务有限公司科研人员合作采用叶碟喷雾法,用螺虫乙酯、乙螨唑及其混剂对柑橘红蜘蛛进行了室内毒力测定,并对筛选出的两种药剂混配的最佳配比进行了田间药效试验。结果表明,螺虫乙酯与乙螨唑混配,各个配比均有增效作用,其中以2∶1(有效成分)的配比增效作用最大,毒性比率和共毒系数分别为 In order to explore the best ratio of the combination of spirotetramat and etoxazole on the combined action of citrus red mite (Citrus red mite), researchers from Jiangxi Agricultural University and Qingnong District Jingin Agricultural Service Co., Ltd. Cooperative use of leaf dish spray method, with spirotetramat, etoxazole and its mixture of citrus red spider conducted indoor toxicity, and screening of the two agents mixed with the best ratio of field medicine Effect test. The results showed that spirotetramat mixed with ethaboxadiazole had synergistic effect in all the proportions, of which the ratio of 2:1 (active ingredient) had the largest synergistic effect, and the toxicity ratio and co-toxicity coefficient were
