Cowpea severe mosaic virus primarily infects cowpea and causes severe mosaic patterns, leaf deformation, stunting, and distorted pods. The virus is mainly transmitted by aphids in a non-persistent manner, but can also spread mechanically through contaminated tools or handling, and occasionally via infected seeds (in cowpea).
3 Known Hosts
Glycine max
soybean
No

Vigna unguiculata
cowpea
Yes

Cowpea severe mosaic virus is primarily transmitted by aphids and can also be spread mechanically through contaminated tools or handling. Seed transmission occurs at a low rate and can serve as an initial source of infection in the field.
Yes
Bioassay, ELISA
Tests have not been standardized.
CPSMV0-7
Biological, Chemical, and Cultural
Use resistant cowpea varieties, manage aphid vectors, practice sanitation and rogueing, and plant virus-free seeds to reduce spread and yield loss.
