摘要

In this research,the inhibitory effect of 16 fungicides on Colletotrichum horri causing persimmon anthracnose was investigated using mycelial growth method and spore germination method.The results showed that among the 16 tested fungicides,10%of Difenoconazole WG,33.5%of Copper quinolate SC,25%of Bromothalonil EC,70%of Mancozeb WP,430 g/L of Tebuconazole SC,50%of Prochloraz-manganese chloride and 400 g/L of Flusilazole EC achieved the best inhibitory effect on mycelial growth of C.horri,with the inhibition rate of 100%;70%of Polyram WG,33.5%of Copper quinolate SC,25%of Bromothalonil EC,70%of Mancozeb WP,50%of Chlorobromoisocyanuric acid AF,50%of Triram WP and 400 g/L of Flusilazole achieved the best inhibitory effect on spore germination of C.horri,with the germination rate of 0.In conclusion,33.5%of Copper quinolate SC,25%of Bromothalonil EC,70%of Mancozeb WP and 400 g/L of Flusilazole EC achieved the best inhibitory effect both in mycelial growth and spore germination,which could be used as the preference fungicides for the control of persimmon anthracnose,and 70%of Polyram WG and 50%of Triram WP achieved the secondly best inhibitory effect,which could be used as alternative fungicides.The results of this research could provide scientific evidence for the effective control of persimmon anthracnose,and more optional pesticides for utilization in the production practice of persimmon industry.
