Abstract:: To research on the occurrence conditions of Xunhua line chilli phytophthora in different cultivated fields types and precipitation was combined to study Xunhua line chilli phytophthora morbidity in Jishi and Chahandousi where were pepper phytophthora prevalent area,during 2009—2014.The results showed that the average morbidity of sand soil fields,half shady half sunlit fields，shady wet field，and soaked field were 4.54%,6.87%,10.63% and 20.69%，respectively；the average morbidity of continuous cropping fields continuous cropping for 1-4 years were 2.61%,5.03%,17.05%,and 26.34%，respectively；the average morbidity of Xinjian village，Jishi，from 2009 to 2014，were 0,10.60%，2.25%，18.30%，7.70% and 12.55%，respectively.The results also indicated that sand soil fields showed the lightest morbidity,followed by half shady half sunlit fields,then，shady wet field，soaked field got the highest morbidity,at the same time,the longer continuous cropping year field，the more seriously the disease occurrence,high precipitation in June was helpful for pepper phytophthora occurrence.All these results provided a theoretical reference for Xunhua line chilli phytophthora preventing and controlling.
