The inhibitory effects of 6 fungicides（prochloraz manganese salt，Fu zinc，phenyletherbromothalonil，
dihydroanthraquinone，difenoconazole，carbendazim-thiram-bromothalonil）on the growth of Colletotrichum lindemuthianum were determined by growth rate method. The results showed that all of these 6
fungicides had inhibitory effect on the pathogen of Colletotrichum lindemuthianum. Among them，80% Fu zinc
WP and 10% difenoconazole WG presented the best inhibitory effects. At the concentration of 1 000 mg·L-1，their
inhibitory rates were 77.68% and 72.96%，respectively，and the EC50 values were 212.41 mg·L-1 and 296.83
mg·L-1，respectively. Thus，80% Fu zinc WP and 10% difenoconazole WG can be used as candidate fungicides
in managing bean anthracnose in the fields.
