Abstract

Six Fungicides were tested in field plot experiments during the years of 2009-2010 to control the potato early blight.The results indicated that Nativo 75% WG 6 000 times,Flint 50% WG 4 000 times,Horizon 43% SC 3 000 times,and Amister 25% SC 1 200 times were all effective.Their control effects ranged from 82.0% to 84.3%.Antracol 70% WP 400 times was next with the control effect 75.9%-76.0%,followed by Mancozeb 80% WP 500 times with 66.2%-66.8%.All of the six fungicides tested could be used to control potato early blight in production field.
