Spray Reports

Lane County’s priority is to administer an Integrated Vegetation Management Program that is open and transparent to the public, ensuring that residents have accessible and accurate information regarding our program and an understanding of the decision making processes that guide our use of herbicide applications. These applications will be limited in use, guided by human and environmental health considerations, and utilize adaptive management that allows flexibility in facing maintenance concerns and challenges as they may 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 reviewed and annually renewed by the Public Health Advisory Committee, as well as approved annually by 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 will publicly post any herbicide application locations on both our roadways and this webpage. Applicable roadways will be posted with signage at least seven days prior to herbicide application and signage will remain a minimum of three days post application. Online public notifications will be posted below under the same guidelines; pre-application notices will be listed at least seven days in advance and all post-application information will remain accessible.
