摘　　要：马铃薯早疫病(Alternaria solani)是国内外马铃薯作物的重要病害,及时试验筛选有效杀菌剂用于生产是非常重要的。2014年通过田间小区方法进行了5种杀菌剂防治马铃薯早疫病(Alternaria solani)试验。结果表明:供试药剂Custodia320SC 30 m L/667m2、Apropo200SE 30 m L/667m2、44%百菌清·苯醚甲环唑悬浮剂120 m L/667m2、40%氟啶胺·异菌脲悬浮剂62.5 m L/667m2和25%阿米西达悬浮剂50 m L/667m2防效分别为96.5%、96.3%、86.3%、80.2%和84.9%,比空白对照增产分别为16.5%、14.4%、9.0%、8.1%和10.1%,均具有显著的防治作用,可作为一个防治马铃薯早疫病的有效药剂应用。Potato early blight（Alternaria solani） was one of important worldwide disease. Screening of effective fungicide was significant for controling potato early blight. Five fungicides were tested in field plot experiments in 2014 to control the potato early blight.The results indicated the control efficacy of Custodia320SC30 mL/667m2, Field plot experiments on the Control of Potato Early Blight by New Fungicides Apropo20OSE30 mL/667m2, daconil-difenoconazole44%SC120 mL/667m2, fluazinam. iprodione40%SC62.5 mL/667m2 and Amister25%SCS0 mL/667m2 compared with the control was individually 96.5%,96.3%, 86.3%,80.2% and84.9%. Their yield increase was respectively 16.5%, 14.4%, 9.0%, 8.1% and 10.1%. All five Fungicides tested could be used to control potato early blight in field production.
