Abstract
The investigations on potato late blight in winter-planting potato fields were conducted in Fuzhou and Changle cites of Fujian province during 2008~2009.The causes of the occurrence and epidemic dynamics of potato late blight were analyzed,the laboratory toxicities of six fungicides to Phytophthora blight were tested by using the method of inhibiting mycelium growth,and their control effects were investigated in field trials.The results showed that the main occurrence and epidemic period of potato late blight was from the second ten-day period of February to the last ten-day period of April,primary disease index,daily mean temperature and relative humidity were major factors affecting the occurrence and epidemic of this disease,when the daily mean temperature was at 18~23 ℃,and the daily mean relative humidity was above 85%,potato late blight would occur generally in 3~7 days.The control effects of dimethomorph,flmnorph,flmnorph-mancozeb,propamocarb hydrochloride fluopicolide and cymoxanil on potato late blight were over 80%.
