2000【性状】纯品为无色结晶体【溶解情况】溶解度(25℃,g/L):水0.0029、丙酮314、甲醇24.四氢呋喃592、二甲苯14。【用途】磺菌胺是一种主要用于土壤处理的杀菌剂。在 600~900g(a.i.)/ha剂量下对白菜的芸苔根肿菌有效,对镰孢(霉)属、疫霉属、腐霉属、丝核菌属和时多粘霉属的 Polymyxabetae、甜菜黄脉病毒的真菌传病媒介(由 rhizomania 引起的甜菜病害)等也有很好的防治效果。【生产单位】1986年由日本三井东亚化学品公司开发的新的土壤杀菌剂。该药剂对白菜根肿病具有显著的效果,离体试验发现对其他作物病原菌也具有很高的灭菌活性。A clean-up procedure with an ion-exchange column in the analysis of flusulfamide by HPLC was examined. Pesticide in the sample was extracted with methanol following liquid-liquid partition with ethyl acetate. The ethyl acetate fraction was cleaned up with silica gel column chromatography. The eluate from the silica gel column was further cleaned up with SAX + PSA mini column, then determined by HPLC. Carotenoids and interfering peaks were removed by washing the combined mini columns with 10 mL of 20% acetone-containing n-hexane and 5 mL of acetone, and flusulfamide was eluted with 35 mL of acetone.http://ng1.17img.cn/bbsfiles/images/2010/12/201012021516_263877_1623180_3.gif
