The present invention provides an isolated biocontrol agent, or a
biocontrol composition, comprising, at least one Pseudomonas strain that
exhibits weed suppressive activity. Preferably, the biocontrol composition
comprises an acceptable medium such as a liquid culture medium, a solid
culture medium, a seed coating, pesta, peat prill, vermiculite, clay,
starch, wheat straw, or any combination thereof. The biocontrol agent or
biocontrol composition may be used to suppress the growth of a weed. The
weed may be selected from the group consisting of green foxtail (Setaria
viridis [L.] Beauv.), foxtail barley (Hordeum jubatum), crabgrass
(Digitaria sanguinalis), annual ryegrass (Lolium rigidum), barnyard grass
(Echinochloa crusgalli), yellow foxtail (Setaria glauca), Italian rye
