Subject:           Updating List of Approved Herbicide Formulations and Adjuvants
 
The 9011 Manual states that “only pesticides that have been analyzed through NEPA (National Environmental Policy Act) documentation can be used in chemical pest control on BLM lands.” Attached is an updated list of herbicide formulations and adjuvants approved for use on BLM administered lands. Fourteen herbicide formulations, representing eight BLM-approved active ingredients and twenty-nine adjuvants have been added to the list. The attached herbicide table identifies the particular active ingredients that may be used in each state. The information is based upon the Vegetation Treatments Using Herbicides on Bureau of Land Management Lands in 17 Western States Programmatic Environmental Impact Statement (PEIS) Record of Decision (ROD) that has been prepared along with the current injunction in place for the state of Oregon. 
 
The manufacturer and EPA registration number is provided to assist in the preparation of the Pesticide Use Proposal. In addition, information is presented identifying whether or not a particular formulation has a California registration number which is required for use of the herbicide in that state.
 
Regarding the adjuvants approved for use on BLM administered lands, refer to the herbicide label and identify which type of adjuvant is required with the particular formulation, i.e., non-ionic surfactant, crop oil concentrate, deposition agent, etc.  Then, refer to the attached list to identify which ones are approved and then select the one that fits the application criteria.
 
Continued emphasis is placed on the correct application of herbicides. Consult the applicable EISs for your area when considering the use of a particular active ingredient.

 

For additional information or questions regarding formulations and adjuvants approved for use on BLM administered lands, contact Gina Ramos, Senior Weed Specialist, WO-220 at (202) 912-7226 or Richard D. Lee, Integrated Pest Management Specialist, National Operations Center at (303) 236-1734 or Richard_Lee@blm.gov
