The invention relates to a synergistic bactericide for preventing and treating sugarcane brown spot. A synergistic bactericidal composition is prepared by binary compounding of coumoxystrobin and oxine-copper, the mass ratio of coumoxystrobin to oxine-copper is (1-25): (100-1). When the two components are compounded, the cotoxicity coefficient is greater than 120 in a certain mass range, and the synergistic effect type is shown; compared with any single component contained in the composition, the composition can improve the control effect on the sugarcane brown spot, can reduce the application dosage of pesticides, and further can reduce pesticide residues and relieve environmental stress. 本发明一种防治甘蔗褐斑病的增效杀菌剂，所述增效杀菌组合物由丁香菌酯与喹啉铜二元复配而成；所述丁香菌酯和喹啉铜的质量比为1-25：100-1。本发明中2种成分在进行复配时，在一定质量范围内，其共毒系数大于120，表现为增效的作用类型；与其包含的任意单一成分相比，可以提高对甘蔗褐斑病的防治效果，可以减少农药的施用剂量，进而可以降低农药残留，减轻环境压力。
