| 摘 要： | 为筛选出香蕉细菌性软腐病的有效防控药剂,通过室内抑菌、盆栽防效以及大田试验,系统开展香蕉细菌性软腐病防治药剂筛选,为生产上的防治提供参考和科学依据。采用含毒介质法中的最低抑制浓度法,测定包括抗生素类和非抗生素类等11种杀菌剂对香蕉细菌性软腐病菌的室内抑菌效果,筛选具有抑菌效果的10种药剂进行盆栽试验,并对4种盆栽试验防治效果较好的药剂开展田间防治试验。结果表明：（1）11种药剂中抗生素类药剂以四霉素抑菌效果较好,抑菌最低有效浓度为1.74 μg/mL,其次为硫酸链霉素、春雷霉素、中生菌素,抑菌最低有效浓度分别为9.10、29.50、89.10 μg/mL;非抗生素类药剂以铜制剂类抑菌效果较好,噻霉酮抑菌最低有效浓度为89.55 μg/mL,其次为王铜、噻菌铜,抑菌最低有效浓度分别为445.00、595.00 μg/mL。（2）春雷霉素的盆栽防治效果较好,防效达67.97%,其次为噻霉酮、中生菌素、噻菌铜,防效分别为64.58%、63.53%、61.83%。（3）春雷霉素防治效果达90.19%,其次为噻霉酮、中生菌素、噻菌铜,防治效果分别为89.84%、84.60%、74.59%。4种药剂对香蕉细菌性软腐病的田间防治效果较好,可作为该病害的防治药剂在生产中交替喷淋应用。

| Abstract: | To screen effective bactericides against banana bacterial soft rot, indoor inhibitory, pot and field experiments were conducted to evaluate the control effect. The minimum inhibitory concentration method in the toxic medium method was used to determine the indoor inhibitory effect of 11 bactericides including antibiotics and non-antibiotics on the banana bacterial soft rot. Ten bactericides with inhibitory effect were selected for pot control experiment. Four bactericides with good pot control effect were selected for field control evaluation. The results are as follows. (1) Among the 11 kinds of antibiotics, tetramycin had good inhibitory effect, and the minimal inhibitory concentration (MIC) was 1.74 μg/mL, followed by streptomycin sulfate, kasugamycin, zhongshengmycin, of which the MIC was 9.10, 29.50 and 89.10 μg/mL, respectively. Among non-antibiotics bactericides’ tests, benziothiazolinone had the greatest inhibitory effect with MIC of 89.55 μg/mL, and the MIC of copper oxychloride and thiodiazole-copper was 445.00 and 595.00 μg/mL, respectively. (2) Pot experiment showed that kasugamycin, benziothiazolinone, zhongshengmycin and thiodiazole-copper had good control effect, with the control effect of 67.97%, 64.58%, 63.53% and 61.83%, respectively. (3) Field experiments showed that the control effect of kasugamycin was 90.19%, followed by that of benziothiazolinone, zhongshengmycin and thiodiazole-copper, which was 89.84%, 84.60% and 74.59%, respectively. In summary, the 4 bactericides have good control effect on banana bacterial soft rot, which could be popularized in production by spraying. |
