摘　　要：采用菌丝生长速率法和孢子萌发法测定了16种常用杀菌剂对柿树炭疽病菌哈锐炭疽菌(Colletotrichum horii)菌丝生长及孢子萌发的影响。结果显示,16种常用杀菌剂中,10%苯醚甲环唑散粒剂、33.5%喹啉铜悬浮剂、25%溴菌腈乳油、70%代森锰锌可湿性粉剂、430 g·L^(-1)戊唑醇悬浮剂、50%咪鲜胺锰盐可湿性粉剂、400 g·L^(-1)氟硅唑乳油、250 g·L^(-1)己唑醇悬浮剂、70%代森联水分散粒剂、22%多菌灵+8%戊唑醇(福连)和50%福美双可湿性粉剂等11种杀菌剂对菌丝生长抑制效果较好,抑制率为95.63%~100%;70%代森联水分散粒剂、33.5%喹啉铜悬浮剂、25%溴菌腈乳油、70%代森锰锌可湿性粉剂、50%氯溴异氰尿酸水溶性粉剂、50%福美双可湿性粉剂和400 g·L^(-1)氟硅唑乳油等7种药剂处理对病原菌分生孢子抑制效果较好,分生孢子萌发率为0~3.33%。其中,33.5%喹啉铜悬浮剂、25%溴菌腈乳油、70%代森锰锌可湿性粉剂和400g·L^(-1)氟硅唑乳油对柿树炭疽病菌菌丝生长和产孢的抑制效果均较好,可作为防治柿树炭疽病的优选药剂,其次为70%代森联水分散粒剂和50%福美双可湿性粉剂,可作为备选药剂。该研究结果可为柿树炭疽病的有效防治提供科学依据和试验数据。In this research,the inhibitory effects of 16 fungicides on Colletotrichum horri causing persimmon 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% bromothalonil EC,70% mancozeb WP,430 g · L^(-1) tebuconazole SC,50% prochloraz-manganese chloride,400 g·L^(-1) flusilazole EC,250 g·L^(-1) hexaconazole SC,70% polyram WG,22% carbendazim + 8% tebuconazole( 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^(-1) flusilazole EC achieved better inhibitory effects on spore germination of C. horri with the germination rate of 0 ~ 3. 33%. Inconclusion,33. 5% copper quinolate SC,25% bromothalonil EC,70% mancozeb WP and 400 g·L^(-1) flusilazole 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.
