摘　　要：The toxicities of several fungicides to Pythium ultimum were determined by the method of mycelia growth. The results showed that hymexazol, Ovraclostrobin＋ Metiram, copper calcium sulphate, Thiophamate-merhyl and Famoxadone＋Cymoxanil all showed good inhibitory effects, of which Hymexazol was the best one with the ECho of 2.631 2 mg/L, followed by Ovractostrobin＋Metiram, whose ECso was 5.303 3 mg/L, and the effects of other fungicides were relatively poor. In the field fungicide screening test, the combination of 70% hymexazol wettable powder and 70% Thiophamate-merhyl had the control efficiency of 95.57%, which was better than the other test combinations, and it was applicable in the field control of tomato basal stem rot.采用菌丝生长法测定了几种杀菌剂对终极腐霉的毒力,结果表明,噁霉灵、唑醚·代森联、硫酸铜钙、甲基硫菌灵和恶酮·霜脲氰对终极腐霉具有良好的抑制效果,其中噁霉灵的毒力最强,EC50值分别为2.631 2 mg/L,唑醚·代森联次之,EC50分别为5.303 3 mg/L,其他药剂效果相对较差。在田间药剂筛选试验中,70%噁霉灵wettable powder与70%甲基硫菌灵wettable powder组合防治效果为95.57%,均优于其它供试药剂组合,可应用于番茄茎基腐病的田间防治。
