摘要
为研制高效稳定的12%甲维·茚虫威悬乳剂,采用直接乳化法,对配方中的润湿分散剂、增稠剂、防冻剂进行筛选,确定最优配方。结果表明,筛选出的最佳配方为甲氨基阿维菌素苯甲酸盐2%、茚虫威10%、环己酮10%、溶剂油150#15%、Agrilan 7884%、Dispersogen LFS 2%、Ethylan NS-500LQ 1%、丙三醇4%、黄原胶0.2%、硅酸镁铝0.6%、有机硅消泡剂SAG 15720.2%,去离子水补足至100%。该配方制得的12%甲维·茚虫威悬乳剂储存稳定性、分散性良好,各项指标均符合检测要求。田间药效试验结果显示,该悬乳剂对甜菜夜蛾的防效较好,在有效成分用量为38 g/hm^(2)时,对甜菜夜蛾药后7 d的防效为86.02%。
To develop efficient and stable emamectin benzoate·indoxacarb 12%SE,the direct emulsification method was used for screening.Wetting dispersants,thickening agents,and antifreezes were evaluated to determine the optimal formulation.The results showed that the optimal formula was as follows:emamectin benzoate 2%,indoxacarb 10%,cyclohexanone 10%,solvent naphtha 150#15%,Agrilan 7884%,Dispersogen LFS 2%,Ethylan NS-500LQ 1%,glycerol 4%,xanthan gum 0.2%,magnesium aluminum silicate 0.6%,silicone defoamer SAG 15720.2%,and deionized added to 100%.The prepared emamectin benzoate·indoxacarb 12%SE exhibited good storage stability and dispersibility,and all indicators met the test requirements.The field efficacy trials demonstrateded that at the active ingredient dosage of 38 g/hm^(2),the emamectin benzoate·indoxacarb 12%SE showed high efficacy against beet armyworm,with the control effect of 86.02%on the 7th day after application.
