| 摘 要： | 为了选择可有效防治番茄早疫病菌的杀菌剂,本文采用组织分离法从罹病叶片分离出病原菌,并通过FAO推荐的菌落直径法测定其对6种杀菌剂的敏感性。结果表明:番茄早疫病对腐霉利最敏感,其平均EC50为1.24μg.mL-1,对杀毒矾、代森锰锌中度敏感,其平均EC50分别为32.64μg.mL-1、56.38μg.mL-1。对百菌清、甲霜灵、异菌脲低度敏感,其平均EC50分别为263.68μg.mL-1、443.33μg.mL-1、605.44μg.mL-1。由此可见,腐霉利对番茄早疫病的防治在试验药剂中效果最好。

| Abstract: | Eight isolates were obtained from tomato diseased leaves and their sensitivities to six fungicides were surveyed.The result showed that they were most sensitive to procymidone(EC501.24 μg·mL-1),moderately sensitive to oxadixyl and mancozeb with an EC50 value of 32.64 μg·mL-1,56.38 μg·mL-1 separately.They were relatively less sensitive to chlorthalonil,metalaxyl,iprodione with an EC50 value of 263.68 μg·mL-1,443.33 μg·mL-1,605.44 μg·mL-1.The result showed that procymidone was very effective preventing Alternaria solani Sorauer in these fungicides. |
