几种杀菌剂对黄瓜细菌性斑点病及大白菜软腐病的抑制作用

Inhibition of Several Fungicides on Pseudomonas syringae pv. Lachrymans in Cucumber and Erwinia carotovora sub sp. Carotovora in Chinese Cabbage

采用抑菌圈法和含毒介质法测定几种杀菌剂对黄瓜细菌性斑点病和大白菜软腐病的抑制作用。结果表明,抑菌效果较好的为农用链霉素、新植霉素和水合霉素;丙森锌对黄瓜细菌性斑点病较好,而对大白菜软腐病则较差;氢氧化铜、噻菌铜及中生菌素抑制作用一般;春雷霉素抑菌活性较差。

The inhibition of several fungicides on Pseudomonas syringae pv. Lachrymans and Erwinia carotovora subsp. Carotovora were tested by the method of bacteriostatic circle and plate toxic medium. The results showed that the better inhibition efficiency to the bacterias was Streptomycin, Streptomycin＋ Terramycin, Oxytetracycline. Lprovalicarb were better on Pseudomonas syringae pv. Lachrymans, but were worse on Erwinia carotovora subsp. Carotovora. Copper hydroxide, thiodiazole and Zhongshengmycin controlled efficacy were not outstanding, Kasugamycin were worse.
