PSDMVF
Pseudomonas viridiflava is a ubiquitous, weak pathogen with a widespread host range. Seed transmission has been suggested, but evidence is limited to artificial inoculation studies showing minimal survival. No confirmed cases of natural seed transmission have been reported. It is primarily spread by rain splash, overhead irrigation, contaminated tools, and contact with infected plant material or debris.

Some sources suggest tomato seed may be a pathway for Pseudomonas viridiflava, but supporting data is limited. Experimental studies with artificially inoculated seed showed limited bacterial survival on the surface. No evidence confirms tomato seed as a natural transmission pathway for P. viridiflava.
Seed treatments such as hot water, sodium hypochlorite, and antibiotics have proven effective in eliminating the pathogen from tomato seeds.
