Abstract

Abstract: 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.
