A biocontrol agent containing one or more novel and isolated Pseudomonas fluorescens strains (P. fluorescens biovar B strain XJ3 (NRRL B-50851), P. fluorescens biovar B strain XS18 (NRRL B-50852), and P. fluorescens biovar A strain LRS 12 (NRRL B-50853)) and a biocontrol agent containing one, two or three of these bacteria with an agriculturally acceptable carrier are useful for the control of annual bluegrass and rough bluegrass root growth and germination. The biocontrol agents of this invention may be applied to the soil and/or seeds in the fall with inhibition occurring in subsequent years. The biocontrol agent can also be used in combination with herbicides that can inhibit the growth and seed production of any standing annual bluegrass and/or fertilizer to stimulate growth of the desirable plant that will compete with the annual bluegrass weed and/or rough bluegrass. Methods for use of these biocontrol agents to control to growth of annual bluegrass and rough bluegrass are also provided.
A method for controlling the growth of annual bluegrass and/or rough bluegrass in an area in need of treatment comprising applying a biocontrol agent effective for controlling annual bluegrass and rough bluegrass root growth and germination comprising one or more Pseudomonas fluorescens strains that inhibit annual bluegrass and/or rough bluegrass root growth and seed germination, wherein said one or more P. fluorescens strains are selected from the group consisting of P. fluorescens biovar B strain XJ3 (NRRL B-50851), P. fluorescens biovar B strain XS18 (NRRL B-50852), P. fluorescens biovar A strain LRS12 (NRRL B-50853), and combinations thereof in an amount effective to control the growth of annual bluegrass and/or rough bluegrass to said area in need of treatment.
A method for controlling the growth of annual bluegrass and/or rough bluegrass in an area in need of treatment comprising applying an agriculturally acceptable carrier, a biocontrol agent, optionally a herbicide, and optionally a fertilizer, in an amount effective to control the growth of annual bluegrass and/or rough bluegrass to said area in need of treatment;
