Rice ragged stunt virus Myanmar (Burma). There were major outbreaks of RRSV and RGSV in China and Vietnam in 2006–2007. Rice ragged stunt virus Rice ragged stunt virus (RRSV) is a plant pathogenic virus of the family Reoviridae. RRSV, vectored by the brown planthopper (BPH) (Delphacidae: "Nilaparvata lugens"), causes ragged stunt disease of rice ("Oryza" spp., especially "Oryza sativa").
