Several strains of Southern bean mosaic virus are known and are very specific to thier host. SBMV-B infects bean (Phaseolus vulgaris) but not cowpea (Vigna unguiculata), SBMV-CP infects cowpea, Ghana strain (SBMV-G) infects cowpeas and some bean cultivars, Mexican strain (SBMV-M) (Severe bean mosaic strain) infects beans and some cowpea cultivars.

Pathway not proven. Seed transmission in cowpea is contradictory, as early reports (Brunt and Kenten, 1973) were done with seed from artificially inoculated plants. Later references (Gillaspie, 1995; Horn, 1991; Jeyanandara and Brunt, 1992)) were unable to detect the virus using direct ELISA tests on seed from naturally infected plants. Virus strain, plant genotype and duration of infection may have affected seed transmission studies (Jeyanandara and Brunt, 1993)

Curtobacterium flaccumfaciens pv. flaccumfaciens (Cff) is a seedborne pathogen that is included in the A2 (high risk) list of quarantine pathogens by EPPO. It can overwinter in plant debris and in weeds. Root damage caused by infections from the root-knot nematode Meloidogyne incognita has been shown to facilitate the entry of pathogens into host plants. The bacterium can multiply quickly in hot and humid weather. Infection is not as visible in temperate climates, therefore lab tests need to be done to confirm infection.
Main: Fabaceae family primarily common bean.

The use of clean seed is the most effective method to prevent spread. Field inspection appears to be inadequate to detect Cff. Weeds, volunteer plants, and plant debris should be removed. There are no effective seed treatments against cff.
