First confirmed report of the benyvirus Rice stripe necrosis virus (RSNV) in Sierra Leone
Source: New Disease Reports
Event: New Location
In 2019, an Oryza sativa (rice) plant in Sierra Leone exhibited leaf crinkling and stripe necrosis. Molecular analyses confirmed that the causal agent was the benyvirus Rice stripe necrosis virus (RSNV). This is the first confirmed report of RSNV in Sierra Leone.
RSNV is an economically important pathogen of rice and has also been reported from other parts of Africa, South America, and Central America. RSNV is not known to occur in the United States. RSNV is a soil-borne virus that can be spread by contaminated agricultural equipment and by the fungus Polymyxa graminis (Plasmodiophorales: Plasmodiophoromycetes), which occurs in the United States. The PEST ID database does not list RSNV (queried 3/11/20).
