8种杀菌剂对黄瓜细菌性角斑病的防治效果
Control Effects of Eight Bactericides on Pseudomonas syringae pv.lachrymans
摘要
Abstract
In order to screen the commercial bactericides for effectively controlling cucumber bacterial angular leaf spot, the MIC, inhibition zone and preventative and therapeutic effects of 8 bactericides were detected by toxic media method and disk diffusion method in laboratory and pot method in greenhouse.The results showed that the MIC of 0.3% tetramycin AS, 80% ethylicin EC, 5% zhongshengmycin WP, 72% streptomycin sulphate SP, 20% copper acetate WP and 46% kocide 3 000 WG was 20, 80, 200, 400, 800 and 2 000 mg/L, respectively.The inhibition zone width of 0.3% tetramycin AS, 5% zhongshengmycin WP, 20% copper acetate WP and 80% ethylicin EC was 1.75, 1.33, 0.93 and 0.90 cm at the concentration of 400 mg/L, respectively.The pot experiments showed that the preventative effect was better than therapeutic effect.The preventative efficacy of 20% thiodiazole-copper SC, 46% kocide 3 000 WG, 5% zhongshengmycin WP, 20% copper acetate WP and 72% streptomycin sulphate SP was 78.9%~82.2%, 78.1%~81.0%, 69.7%~78.3%, 61.7%~63.1% and 57.1%~65.0% at the concentration of 200~400 mg/L, respectively.Comprehensively considering, 20% thiodiazole-copper SC, 46% kocide 3 000 WG, 5% zhongshengmycin WP, 20% copper acetate WP and 72% streptomycin sulphate SP had effective control effect on cucumber bacterial angular leaf spot.关键词
