Cheatgrass suppressive bacteria Pseudomonas fluorescens D7 now registered in Montana (Pesticides)
Description: Pseudomonas fluorescens D7 was registered in 2014 as a bio-herbicide for suppression of cheatgrass (Bromus tectorum) under the trade name D7® by Verdesian Life Sciences, LLC, Cary, NC. D7 is now registered in Montana for use on wheat, barley, triticale, oats, and rangeland. See attached label and March Weed Post outlining D7 as well as two other P. fluorescens strains that are being developed for cheatgrass suppression. D7 is a freeze-dried powder that is dissolved in water and applied as a spray solution. D7 is a cold-loving organism that is best applied in late fall with cool temperatures, overcast skies, and rain. It stunts root growth and overall vigor of cheatgrass by colonizing intercellular spaces in the roots and producing compounds that inhibit cellular growth in seedlings. D7 has been shown to inhibit some native grasses, especially when plants are stressed due to other environmental factors.
