为制备直播棉种子用25%噻虫嗪·多菌灵·吡唑醚菌酯种子处理悬浮剂(25%噻·多·唑醚FS),分别采用流点法及正交试验设计对主要助剂进行筛选,并合成了可溶性淀粉-苯乙烯二元共聚物成膜剂,对25%噻·多·唑醚FS质量指标进行了测定,评价其对棉花种子发芽率、幼苗叶绿素、游离脯氨酸含量的影响。所制备制剂中,有效成分噻虫嗪、多菌灵和吡唑醚菌酯分别为10%、10%和5%,润湿分散剂W600和D800、黏度调节剂黄原酸胶和硅酸镁铝的质量分数分别为2.5%和4.0%、0.18%和0.30%,防冻剂乙二醇5%,色浆海舒液体红2R 2%。经测定,25%噻·多·唑醚FS黏度为204.21 mPa·s,粒径D90、D50、D10分别为1.25、0.82、0.35 μm,离心...

To prepare 25% thiamethoxazine carbendazim pyraclostrobin suspension concentrate(25% thi car pyr FS) for cotton seeds treatment for direct seeding, the main additives in the formulation were screened by flow point method and orthogonal design. The soluble starch-styrene binary copolymer film former was synthesized and the performance of the film former was determined. The quality index of 25% thi car pyr FS was determined and its effect on cotton seed germination rate, seedling chlorophyll content and free proline content was evaluated. The act...
