Abstract：In this research,the inhibitory effects of 16 fungicides on Colletotrichum horri causing persim-mon anthracnose were investigated using mycelial growth and spore germination methods.The results showed that among the 16 tested fungicides,10%difenoconazole WG,33.5%copper quinolate SC,25%bromotha-lonil EC,70% mancozeb WP, 430 g· L-1tebuconazole SC, 50% prochloraz -manganese chloride, 400 g· L-1flusilazole EC,250 g· L-1hexaconazole SC,70% polyram WG,22% carbendazim+8% tebucon-azole(Fulian),and 50%thiram WP achieved better inhibitory effects on mycelial growth of C.horri with the inhibition rate of 95.63%~100%;70%polyram WG,33.5%copper quinolate SC,25%bromothalonil EC, 70%mancozeb WP,50%chlorobromoisocyanuric acid SP,50%thiram WP and 400 g· L-1flusilazole EC a-chieved better inhibitory effects on spore germination of C.horri with the germination rate of 0~3.33%.In conclusion,33.5%copper quinolate SC,25%bromothalonil EC,70%mancozeb WP and 400 g· L-1flusi-lazole EC achieved the best inhibitory effects both on mycelial growth and spore germination,so they could be used as the preference fungicides for the control of persimmon anthracnose.The fungicides of 70%polyram WG and 50%thiram WP also achieved better inhibitory effects,and they could be used as the alternative fungicides. These results could provide scientific references and data for effective control of persimmon anthracnose.
