Abstract
The experiment was to determine the field control efficacy of seven fungicides to potato late blight.The results indicated that the control efficacy of Fluopicolide 68.75% SC(1 125 g / ha),Ridomil Gold-MZ 53% WG(1 500 g / ha),Flumorph + Mancozeb 60% WP(1 225 g / ha) and Curzate 72% WP(2 000 g / ha) were 88.38%,86.15%,84.55% and 81.68%,respectively.These were ideal chemicals to control potato late blight,and obvious for yield increase.Thus,these fungicides should be recommended for use alternatively in potato production.
