摘要: 笔者旨在通过筛选防治番茄茎腐病的有效药剂,为田间防治提供指导。室内测定了5 种杀菌剂对终极腐霉菌丝生长的抑制作用,恶霉灵、唑醚·代森联、硫酸铜钙、甲基硫菌灵和恶酮·霜脲氰为有效杀菌剂。研究结果表明:恶霉灵的EC50为0.364 mg/L,抑菌效果最好;唑醚·代森联效果次之,EC50为9.247 mg/L,其他药剂防治效果相对较差。在田间药剂筛选试验中,70%恶霉灵可湿性粉剂与70%甲基硫菌灵可湿性粉剂组合防治效果为95.57%,均优于其它供试药剂组合,可应用于番茄茎腐病的田间防治。

Abstract: The paper aims to screen out effective fungicides to control tomato basal stem rot and provide guidance for field control. Inhibiting effect of 5 fungicides on the growth of Pythium ultimum was investigated indoor. The test verified that the 5 fungicides, hymexazol, ovraclostrobin·metiram, copper calcium sulphate, thiophanate-methyl and famoxadone·cymoxanil, had control effect on the growth of Pythium ultimum. The results showed that hymexazol had the best antibacterial effect with the EC50 value of 0.364 mg/L, then was ovraclostrobin·metiram with the EC50 value of 9.247 mg/L, other fungicides had poor control efficiency. In field fungicide screening test, the combined control efficiency of 70% hymexazol WP and 70% thiophanate-methyl WP was 95.57%, which was better than other combinations and could be used in field control.
