| 摘 要： | 【目的】筛选抑制解淀粉欧文氏菌的药剂类型,为解淀粉欧文氏菌(Erwinia amylovora)引起病害的药剂防治提供科学依据。【方法】采用最低抑制浓度和抑菌圈的方法,测定5大类10种杀菌剂对解淀粉欧文氏菌的室内毒力。【结果】有机杂环类杀菌剂对解淀粉欧文氏菌的室内药效最强,对应药剂EC50值为43.148 mg/L,其后按EC50值由小到大的排序为抗生素类杀菌剂、噻唑类杀菌剂、微生物杀菌剂和铜制剂杀菌剂,对应药剂EC50分别为87.82、469.50、4 397.20和4 782.00 mg/L。【结论】有机杂环类、抗生素类杀菌剂抑菌效果良好。

| Abstract: | 【Objective】 To screen the types of fungicides that can inhibit Erwinia amylovora in the hope of providing theoretical basis for the prevention and control of diseases caused by Erwinia amylovora.【Method】 The indoor toxicity of 5 categories and 10 fungicides to Erwinia amylovora was determined using the method of minimum inhibitory concentration (MIC) and bacteriostatic zone.【Result】 Organic heterocyclic fungicides had the strongest indoor efficacy against Erwinia amylovora, with the EC50 value of 43.148 mg/L, followed by antibiotic fungicides, thiazole fungicides, microbial fungicides and copper fungicides in descending order and the corresponding EC50 value was 87.82,469.50,4,397.20 and 4,782.00 mg/L, respectively.【Conclusion】 Organic heterocyclic and antibiotic fungicides have good antibacterial effect, which can provide references for the prevention and control of diseases caused by Erwinia amylovora. |
