摘 要：
在实验室条件下,分别测定了1.5%卡松对棉花枯萎病菌、棉花红腐病菌、棉花红粉病菌、棉花黄萎病菌和棉花疫病菌等5种重要植物病原真菌及水稻白叶枯病菌、大白菜软腐病菌等两种重要植物病原细菌的抑制活性。结果表明,1.5%卡松对棉花枯萎病菌的MIC和EC50分别为40mg/L和9.2034mg/L,对棉花红腐病菌的MIC和EC50分别为40mg/L和0.7845mg/L,对棉花红粉病菌的MIC和EC50分别为20mg/L和0.6951mg/L,对棉花黄萎病菌的MIC和EC50分别为20mg/L和2.8383mg/L,对棉花疫病菌的MIC和EC50分别为2mg/L和0.3459mg/L;对水稻白叶枯病菌和大白菜软腐病菌的MIC分别为1mg/L和10mg/L;说明该药剂对供试7种植物病原菌均具有良好的抑制活性,尤以对棉花疫病菌和水稻白叶枯病菌的抑制活性较强。

摘 要：
The inhibitory activity of 1.5% Kathan was tested against five plant pathogenic fungi and two plant pathogenic bacteria under laboratory conditions. The minimum inhibitory concentrations (MIC) of 1.5% Kathan for Fusarium oxysporum f.sp. vasinfectum,F. moniliforme,Trichothecium roseum,Verticillium dahliae,and Phytophthora boehmeriae were 40,40,20,20,and 2 mg/L,respectively,while EC50s were 9.20,0.785,0.695,2.84,and 0.346 mg/L,respectively. MIC of 1.5% Kathan for Xanthomonas oryzae Dowson,Erwinia carotovora PV. carotovora were 1 and 10 mg/L,respectively. These results suggest that Kathan has good inhibitory activity against the 7 pathogens tested,especially against P. boehmeriae and X. oryzae Douson
