采用旋转包衣法研制出1%噻虫嗪·联苯菊酯颗粒剂。采用优选组合法对多种助剂进行筛选,确定最优配方为:噻虫嗪0.5%、联苯菊酯0.5%;木质素磺酸钠0.1%;着色剂0.1%;白炭黑0.8%;JPPC-02 1.4%;凯松0.004%;黄原胶0.002%;硅酸铝镁0.006%;水0.79%;河砂补至100%。田间药效试验表明,该颗粒剂对黄曲条跳甲有较好的防治效果,在450和600g/hm~2有效成分的用量下,药后15d对成虫和幼虫的防治效果均在80%以上,显示出较强的应用前景和开发价值。
1% thiamethoxam · bifenthrin granules were developed by rotary coating method. The optimal combination of thiamethoxam 0.5%, bifenthrin 0.5%, sodium lignin sulfonate 0.1%, colorant 0.1%, white carbon 0.8% JPPC-02 1.4%; Cassia 0.004%; Xanthan Gum 0.002%; Magnesium Aluminum Silicate 0.006%; Water 0.79%; The field efficacy test showed that the granules had a good control effect on the yellow beetle flea beetle. Under the dosage of 450 and 600g / hm ~ 2 active ingredients, the control effect on the adults and larvae was 15% after 80 days, Above, shows a strong application prospects and development value.
