What can folks do about it?

goatsrueControl Where it Goes

Clip any flowers or seedpods you see and throw them in the trash. Regular visits to the site are necessary to deal with the new flowers that usually occur later in the growing season

Control Where it Grows

  • Dig: Well, actually, digging has not been attempted; given its deep roots, manual removal is not expected to be a good long-term management strategy.
  • Treat: Trials are ongoing throughout the Portland area to determine the most effective herbicide and rate.
  • Check: monitor the site at least annually, and especially years two and three after treatment, as any surviving seed takes its big opportunity to sprout!

Last Words

Because goatsrue is a federally-listed noxious weed, many agencies need about new patches. If you suspect you’ve found goatsrue, the Oregon Department of Agriculture, the US Department of Agriculture, and the City of Portland all REQUIRE you to report it.  You can report suspected patches to:

  • the Oregon Department of Agriculture at 1-866-INVADER (1-866-468-2337), or;
  • Mitch Bixby with the Environmental Services' Early Detection/Rapid Response Program at 503-823-2989 or

The City of Portland offers assistance with managing goatsrue if you would like it.
