The invention relates to a fungicidal mixture, in particular to a fungicidal mixture containing boscalid and chlorothalonil active ingredients. The weight ratio of boscalid to chlorothalonil is 1:100-100:1. The amount of boscalid and chlorothalonil accounts for 5-90% of the fungicidal mixture. By binary mixing of boscalid and chlorothalonil, the prepared fungicidal mixture has a synergistic control effect, expands the fungicidal spectrum and achieves multiple effects with one formulation. Moreover, the modes of action of boscalid and chlorothalonil are different. Hence, the effect of disease prevention can be enhanced and the drug resistance of pathogenic fungi is not developed easily.
