| 摘要 | [Objectives] The paper was to explore the occurrence and mixed infection of sugarcane bacilliform virus disease in Hainan sugarcane-growing area. [Methods] A total of 348 sugarcane leaf samples were collected from 7 sugarcane-growing areas in Hainan Province. Molecular detection of sugarcane bacilliform virus (SCBV) was carried out by PCR using specific primers. [Results] SCBV was detected in 244 out of 348 sugarcane samples, with an average detection rate of 70.11%. The highest detection rate was 76.66% in the Danzhou sugarcane-growing area, while the lowest was 57.14% in the Baisha sugarcane-growing area. The SCBV-positive samples were subjected to testing for SCYLV, SCSMV, SrMV, and SCMV, respectively. The results indicated that 106 out of 244 positive samples exhibited a single infection with SCBV, while 138 samples exhibited mixed infections with SCBV and other sugarcane viruses. The proportion of mixed infections among the SCBV-positive samples was as high as 56.56%. Among the various types of mixed infections, two-virus and three-virus mixed infections were the most prevalent. [Conclusions] SCBV has emerged as a significant threat to the secure production of sugarcane in the Hainan sugarcane-growing region. It presents an explosive infection in the Hainan sugarcane-growing region and frequently combines with other sugarcane viruses to infect sugarcane. The findings of this study will provide a theoretical foundation for the prevention and control of sugarcane bacilliform virus disease. |
