Composition for preventing and treating plant bacterial diseases and application

The invention discloses a compound composition containing ethylicin and Xinjunan acetate and application of the composition. The effective components of the composition comprise ethylicin and Xinjunan acetate, and the mass ratio of ethylicin to Xinjunan acetate is (30:1)-(1:10). According to the invention, ethylicin and Xinjunan acetate are taken as effective components to compound the bactericide, so that the bactericide has an obvious synergistic effect when being used for preventing and treating plant bacterial diseases, the prevention and treatment effect is improved, the generation of drug resistance of pathogenic bacteria is delayed, the use amount of the effective components is reduced, and the use cost for preventing and treating the diseases is reduced. 本发明公开了一种含有乙蒜素和辛菌胺醋酸盐复配组合物及其应用，所述组合物有效成分包含乙蒜素和辛菌胺醋酸盐，乙蒜素和辛菌胺醋酸盐质量比为30：1～1:10。本发明以乙蒜素与辛菌胺醋酸盐为有效成分复配杀菌剂，用于防治植物细菌性病害表现出明显的协同增效作用，提高防治效果，延缓病原菌抗药性产生，减低有效成分使用量以及减少防治病害的使用成本。
