[Aims]In order to reduce the dosage of chemical fungicides and improve the control efficacy,we explored the combined action of Bacillus valesiae TCS001 and chemical fungicides against grey mold in strawberry.[Methods]The mycelial growth rate method was used to determine the bioactivity of the fungicides in vitro,the net turbidity method was used to determine the compatibility of TCS001 with the chemical fungicides,the Colby method was used to evaluate the efficacy of the mixture,and the field trails were carried out.[Results]TCS001,having obvious inhibitory effect on B.cinerea,was compatible with boscalid and fluxapyroxad.The mixtures of 1 x 107 CFU/mL of TCS001 and 100 mg/L of boscalid showed 14.19％higher control efficacy than that expected,indicating a synergistic effect.In the field,the highest efficacy against strawberry grey mold was achieved by mixture of TCS001 and boscalid(66.77％).[Conclusions]The combined application of TCS001 and boscalid can effectively control gray mold of strawberry.
