摘要
[目的]为开发合格的42%精异丙甲草胺·异[口恶]唑草酮·莠去津悬乳剂产品。[方法]试验通过对乳化剂、润湿分散剂、稳定剂、增稠剂、防冻剂、消泡剂、防腐剂等不同助剂的筛选,确定各助剂用量及比例。混合液经充分剪切和砂磨2 h后,与油相体系再次混合剪切,最终得到稳定的样品。[结果]该产品在贮前、贮后外观稳定,不结块、不析水,且有效成分悬浮率均达到98%以上,流动性好,热贮分解率在5%以下。同时,通过田间药效试验结果说明该产品在玉米田封闭效果及持效期显著优于市场同类产品。[结论]该产品稳定性高、药效突出,具有优异的推广和应用价值。
[Aims]This study aims to develop the steady stable production of the S-metolachlor·isoxaflutole·atrazine42% SE. [Methods]We had filtrated the different formulation adjuvants including the emulsifier, wetting and dispersing agent, stabilizing agent, thickening agent and antifreeze, antifoaming agent, preservatives, which were adding into the two raw materials of isoxaflutole and atrazine, and then we had by shearing and grinding for 2 hours, and mixing with the oil phase of S-metolachlor and final the dosage proportion were determined. [Results]Experiments results shown that the S-metolachlor·isoxaflutole·atrazine 42% SE had stable appearance, noncaking, without separating water, and the effective components had high suspending rate, fine fluidity, the rate stability of the hot storage precipitation was 5% blow, and the suspending rate can be raised more than 98%. Meanwhile, the blocking and lasting effects of the product in corn field trial were significantly better than the similar products in the market. [Conclusions]Above all, the production had high stability, outstanding effects and good value for promotion and application.
