Use of Pseudomonas fluorscens as a bioherbicide for cheatgrass and other invasive winter annual grass control

Publication #: B-1296
Date Published: 01/09/2017

Publication Author(s):
Daniel R. Tekiela

Description:
Work over the past 15 years has identified unique strains of the ubiquitous soil bacteria Pseudomonas flourescens to control invasive annual grasses. These strains were originally identified from wheat fields in Washington with annual grass injury. From those, specific strains were identified that are reported to only affect certain invasive annual grasses. These strains colonize intercellular space in the roots of the target invasive annual grass and reduce plant growth by inhibiting root cell membrane production. This results in stunting of the target plant. There are currently two strains potentially being utilized as bioherbicides, D7 and ACK55.
