Abstract：Twenty-one bactericides were used to assay the toxicity to Xanthomonas campestris pv. vesicatoria, which could provide references for the selection of bactericides in felids. The results showed that streptomycin, dichloroisocyanuric acid sodium and streptomycin+oxyteracykine had obvious toxicity to Xanthomonas campestris pv. vesicatoria, and their EC50 value were 35 582, 925 186 and 1 948 mg?L-1, respectively. Certain concentration proportional streptomycin and streptomycin + oxyteracykine, dichloroisocyanuric acid sodium and streptomycin + oxyteracykine had the synergic effects on the toxicity to Xanthomonas campestris pv. vesicatoria, while dichloroisocyanuric acid sodium and streptomycin showed independent effects on the toxicity to Xanthomonas campestris pv. vesicatoria.
