Four frequently used fungicides were compared in various concentrations for potato late blight control efficacy in a randomized complete block design. 687.5 g/L Fluopicolide SC and 75% Mancozeb WDG were proved to be more effective for late blight control. When amount of fungicide used and labor cost were considered, Fluopicolide should be used at a rate of 125 mL/667 m2 two times or 75 mL/667 m2 three times, while Mancozeb be used at a rate of 100 g/667 m2 three times or 200 g/667 m2 two times.
