Weed-suppressive bacteria- A factsheet
Weed-Suppressive Bacteria, or WSB, are bacteria strains of the soil bacterium Pseudomonas flourescens (D7, ACK55, and MB906) developed and marketed as a natural way to control exotic grasses, such as cheatgrass. In the late 1900s and early 2000s, scientists began experiments that looked for biological ways to selectively eliminate or inhibit growth of exotic annual grasses.
