The results showed that the overall control effect of 45% propamocarb · fenamidone SC against potato late blight on the 14^th day after the third spraying were 67.64% -83.78%. The yield of potato reached 19 972.5 -23 302.5 kg/hm^2, with higher marketable tuber rate and lower rotten tuber rate. With the increase in fungicide dose, the difference in control effect against late blight was significant, but the yield-increasing effect on potatoes was not significant.
