Development and Evaluation on the Pesticide Effect of 30% of Spirotetramat·Flonicamid Suspension Concentrate

Henan Hansi Crop Protection Co., Ltd., Shangqiu Henan 476000, China

摘要: 为了有效防控苹果蚜虫等作物虫害,开展了30%螺虫乙酯·氟啶虫酰胺水悬浮剂的配方研制及药效评价研究.本研究采用湿法研磨工艺筛选出了适宜的润湿分散剂、结构稳定剂、防冻剂、消泡剂、增效剂等助剂种类及其用量,确定了30%螺虫乙酯·氟啶虫酰胺水悬浮剂产品的最佳配方,即螺虫乙酯20%,氟啶虫酰胺10%,EO/PO嵌段聚醚(500LQ)1%,多聚芳基醚硫酸酯(FD)3%,乙氧基多聚芳基酚磷酸酯铵盐(SC)2%,增效剂甲基化聚醚改性聚合物(Prime)5%,乙二醇5%,苯甲酸钠0.3%,消泡剂630 0.5%,黄原胶0.15%,硅酸镁铝1%,去离子水补足.结果表明,该配方做出来的产品悬浮率大于90%,热贮14 d后分解率小于3%,各项技术指标均符合水悬浮剂的指标要求.根据室外生测试验表明,对苹果蚜虫有较高的防治效果,1 000倍液喷雾,药后15 d防效98.02%,达到试验设计初衷.

Abstract: In order to effectively prevent and control the croppests such as apple aphids, the formulation and efficacy test of 30% spirotetramat·flonicamid SC. suspension concentrate (SC) were studied.The suitable wetting dispersant, structural stabilizer, antifreeze, foaming agent, and additives were selected by wet grinding process.The optimized formula of 30%spirotetramat·flonicamid SC was determined as 20% of spirotetramat, 10% of flonicamid, 1% of 500LQ, 3% of FD, 2% of SC, 5% of Prime, 5% of glycol, 0.3% of sodium benzoate, 0.5% of 630, 0.15% of xanthan gum, 1% of magnesium aluminum silicate, and supplement of deionized water.The results show that the suspension rate of the formula is more than 90%, and the decomposition rate is less than 3% after 14 d of thermal storage. All the technical indexes met the requirements of the water suspension agent.According to the outdoor bioassay test, According to the outdoor bioassay test, the control effect of 1 000 time liquid spraying on apple aphids reached 98.02% 15 days after spraying, which met the original intention of the experimental design.
