Interpretive Summary: Mosaic is one of the most important sugarcane diseases and is caused by single or mixed infections of Sugarcane mosaic virus, Sorghum mosaic virus, and/or Sugarcane streak mosaic virus. The compound infection of mosaic becomes increasingly serious lately. The disease directly affects the photosynthesis and growth of sugarcane, leading to a significant reduction in both cane and sugar yields, and thus causes serious economic losses. This review covers four aspects of sugarcane mosaic disease management. First, the current situation of sugarcane mosaic disease and its epidemic characteristics; second, the pathogenicity and genetic diversity of the three viruses; third, the diagnostic and identification methods of sugarcane mosaic species and its pathogenic species; and fourth, the prevention and control measures for sugarcane mosaic disease and potential future research focus. The review is expected to provide scientific literature and guidance for effective prevention and control of mosaic through resistance breeding in sugarcane.

Technical Abstract: Mosaic is one of the most important sugarcane diseases, causing by single or compound infection of Sugarcane mosaic virus (SCMV), Sorghum mosaic virus (SrMV), and/or Sugarcane streak mosaic virus (SCSMV). The compound infection of mosaic becomes increasingly serious lately. The disease directly affects the photosynthesis and growth of sugarcane, leading to a significant decrease in cane yield and sucrose content, and thus serious economic losses. This review covers four aspects of sugarcane mosaic disease management: First, the current situation of sugarcane mosaic disease and its epidemic characteristics; second, the pathogenicity and genetic diversity of the three viruses; third, the identification methods of mosaic and its pathogen species; and fourth, the prevention and control measures for sugarcane mosaic disease and potential future research focus. The review is expected to provide scientific literature and guidance for effective prevention and control of mosaic through resistance breeding in sugarcane.
