Abstract
The meteorological condition of occurrence and epidemic of potato late blight and its yield loss were analyzed by using the late blight data of two potato varieties planted in Poshang village with an elevation of 2 230～2 280 m in 2008.The results showed that when the continuous rainfall days were over 5 d,mean daily temperature was below 13℃ and mean daily sunshine duration was less than 4 h from the last ten-day period of April,the potato late blight would emergence,and when the daily precipitation ratio of 5 continuous rainfall days was ≥0.1 mm,mean daily temperature was below 17℃ and mean daily sunshine duration was less than 3 h from the last ten-day period of May,the potato late blight would emergence seriously.The main epidemic period of potato late blight is from the last ten-day period of May to the middle ten-day period of June and the disease index of Weiyu 3 is 0.4～19.8 higher than Hui-2.The average yield of the un-control plot is 9.63 t/hm2 lower than the yield of the control plot.The paper puts forward the countermeasures for controlling potato late blight.
