Rice stripe necrosis (RSNV) is caused by a virus transmitted by the soil-borne fungus Polymyxa graminis. The disease is characterized by seedling death, leaf stripes and necrosis, and plant malformation. The disease was reported by Louvel and Bidaux in 1977 in Côte d’Ivoire, West Africa, and the virus was isolated by Fauquet and Thouvenel in 1983.
