The U.S. Department of Agriculture’s Animal and Plant Health Inspection Service (APHIS) has prepared a final environmental assessment (EA) regarding the biological control of yellow toadflax, Linaria vulgaris. Yellow toadflax is considered a serious invasive plant in pastures and croplands that displaces other native and planted forage species and is difficult to control. APHIS experts analyzed the effect releasing a stem gall weevil, Rhinusa pilosa, as a biological control agent could have on the human environment and determined its release will not have a significant impact. On October 2, 2017 APHIS published an EA in the Federal Register for public review and comment, and extended the comment period an additional 15 days at the request of a stakeholder. After reviewing comments received, APHIS prepared the final EA and made the finding of no significant impact. This action will allow the issuance of permits to release the stem gall weevil.
