Rice grassy stunt virus explained

Rice grassy stunt virus (RGSV) is a plant pathogenic virus transmitted by the brown planthopper, Nilaparvata lugens, and two other Nilaparvata species, N. bakeri and N. muiri.^{[1] [2]}

The virus is found in South and Southeast Asia, China, Japan, and Taiwan.^[3] From 1970 to 1977, RGSV incidence was high in Indonesia. Outbreaks occurred in the Philippines from 1973 to 1977 and again from 1982 to 1983.^[4] There was significant crop loss from RGSV in parts of India in 1972–74, 1978, 1981, and 1984.^{[5] [6]} High levels of RGSV were reported in Kyushu, Japan in 1978.^[7]

From 2000 to 2008, the Mekong Delta of Vietnam experienced major crop losses of rice as RGSV and rice ragged stunt virus, also vectored by N. lugens, occurred together.^{[8] [9] [10] [11]}
