Southern rice black-streaked dwarf virus (SRBSDV) is a plant pathogenic virus of the family Sedoreoviridae, causing diseases in rice and maize, resulting in significant crop losses in Southern Asian countries.

The sole transmitter of SRBSDV is Sogatella furcifera, aka the "white-backed planthopper" (WBPH).

Close relative to the Laodelphax striatellus (small brown planthopper), which transmits the RBSD virus.

[3] Since then, it has spread to other parts of East Asia, causing serious damage to rice and maize crops in countries like China, Vietnam, and Japan.

[4] Most affected countries have already implemented preventative actions, such as nets to protect crops, treating seeds with chemicals, and spraying seedlings with pesticides.
