Abstract In order to identify the kinds and development trends of pepper diseases in China,a total of 105 samples with suspected infected symptoms of virus diseases were collected in the main pepper producing areas of 16 provinces (municipalities,autonomous regions) in China from 2018-2019.The 12 major pepper viruses were detected by double antibody sandwich enzyme-linked immunosorbent assay (DAS-ELISA).The results showed that 70 samples were infected with virus diseases.The virus detection rate was 66.67%,and 10 kinds of viruses were detected.Among them,PMMoV had the highest detection rate-24.76%,followed by CMV,BBWV-1,2,TEV and TSWV.Their detection rates were 19.05%,12.38%,12.38%,and 10.48%,respectively.The complex infection of multiple viruses is relatively common in the pepper producing areas of China.The complex infection rate of viruses was 40%.Among them,the complex infection rate of 2 kinds virus was the highest reaching 28.57%.Comparing the virus disease testing results between 2018 and 2019,the detection rate of 7 viruses had arising trend.In summary,this study found that PMMoV and CMV were the severer viruses harming China's pepper production in recent 2 years.In addition,PMMoV,BBWV-1,2,TEV,and TSWV damages were on the rise having epidemic risk.
