【摘要】 研究了杀菌剂药剂稀释方法、药液保存时间对杀菌剂平板法生物测定稳定性的影响。表明 ,药剂以 2 / 3的比例系列稀释时多次测定标准差最小 ,表现最稳定。井冈霉素溶解于水冰箱保存 14d ,对小麦纹枯病菌的活性基本不变化 ,说明这种药剂在溶剂水中较稳定 ;福美双以丙酮溶解后降解速度较快 ,第 0天 ,EC50 =1 7394 ;第 13天 ,EC50 =5 6 2 2 4。更多还原

【Abstract】 Fungicides including the method of dissolution and preserved time of germicide had been studied on bioassay stability The experiment indicated Tebuconazole dissolved in HCOOH had the ministandard error with 2/3 proportion Bioactivity of Validamycin to Rhizoctonia can be maintained till 14 days when dissolved in water Thiram degraded quickly when dissolved in aceton更多还原
