The effects of streptomycin sulfate, carbendazim, penicillin and nystatin on the inhibition of fungi and bacteria in blueberry explants were studied. The results showed that the addition of streptomycin sulfate or penicillin with different concentrations in the medium had a certain inhibitory and killing effect on bacteria in blueberry explant contamination, while the addition of carbendazim or nystatin had a certain inhibitory and killing effect on fungi in blueberry explant contamination. When the concentration of streptomycin sulfate in the medium reached 60units / mL, the highest survival rate was 44.0%, and the bacterial infection rate was the lowest. When the concentration of carbendazim in the medium was 0.4 mg/mL, the survival rate reached 40.5%, and the fungal infection rate decreased greatly. When the penicillin concentration in the medium reached 40mg/mL, the lowest infection rate of bacteria was 4.0%, and the highest survival rate was 31.5%. When the concentration of nystatin in the medium reached 40mg/L, the highest survival rate was 34.5%. Therefore, streptomycin sulfate had better inhibitory effect on bacteria, while carbendazim had better inhibitory effect on fungi, which provided reference for future research.
