摘　　要：[目的]最大限度阻止或延缓黄瓜细菌性角斑病对噻唑锌的抗药性发生和抗药性群体的形成,延长噻唑锌的使用寿命,确保化学防治效果。[方法]紫外诱变和药剂驯化获得突变体。采用浊度法测定抗药性突变体的抗药性水平、交互抗药性、抗药性遗传稳定性。[结果]该突变体对噻唑锌表现为低抗药水平,抗药性突变体不稳定。抗药性突变体与8-羟基喹啉铜、双唑锌无交互抗药性。[结论]黄瓜细菌性角斑病对噻唑锌的抗药性风险比较低。[Aims] Maximize prevent or retard the occurrence of thiazole zinc-resistance and thiazole zinc-resistance groups formed on cucumber bacterial angular leaf spot. Extend useful life of thiazole zinc. Ensure the chemical control effect. [Methods] Get resistant mutants by chemical taming and UV irradiation. Determined resistance levels of resistant mutants, cross resistance, resistance to genetic stability by turbidity method. [Results] The thiazole zinc mutant exhibit low levels of drug resistance. Resistant mutants instability, no cross resistance between thiazole zinc-resistant mutants and 8-hydroxyquinoline copper, double azole zinc. [Conclusions] Thiazole zinc-resistance risk on cucumber bacterial angular leaf spot is relatively low.
