Lane County’s priority is to administer an Integrated Vegetation Management Program that is open and transparent to the public, ensuring residents have accessible and accurate information regarding treatments and the decision making processes that guides our use of herbicides. Herbicide applications are limited in use and follow adaptive management approaches that allow flexibility when facing maintenance concerns and challenges as they arise.


Permitted Product List
Lane County Road Maintenance Division has three herbicide products that have been approved for use and make up our Permitted Product List. These products have been annually reviewed and approved by the Public Health Advisory Committee and the Board of Health. 

Vastlan - - active ingredient triclopyr
Milestone - - active ingredient aminopyralid
Ecomazapyr 2SL - - active ingredient imazapyr


Public notifications
As part of the transparency process, Lane County Roads Division will post any upcoming right-of-way herbicide application locations on this webpage. Pre-application notices will be listed by  road name at least seven days prior to treatment for any guardrail and noxious weed sites. Notices will remain a minimum of three days post application and will be marked as completed.
