A total of 21 kinds of pests and diseases were found on blueberry,including 10 kinds of diseases and 11 kinds of pests. Comprehensive analysis of pests and diseases and their damage degree revealed that pests and diseases causing severe damage were gray mold,scarab and fruit fly,while gray mold and fruit fly might seriously affect the export of blueberry. The prevention and control measures against gray mold and fruit fly were summarized.展开更多
