Subject: Updating List of Approved Herbicide Formulations and Adjuvants

Attached is an updated list of herbicide formulations and adjuvants approved for use on Bureau of Land Management (BLM) administered lands. Fifty-eight formulations, representing 14 BLM approved active ingredients, and 16 adjuvants have been added to the respective lists or had labeled information updated. Continued emphasis is placed on the correct application of herbicides. Consult the applicable Environmental Impact Statement (EIS) for your area when considering the use of a particular active ingredient. The attached herbicide table identifies the states each particular active ingredient may be used in. The information is based upon the Records of Decision (ROD) that have been prepared along with the current injunction in place for the state of Oregon. The EISs involved included: 1) Northwestern Area Noxious Weed Control Program, 2) California Vegetation Management, 3) Vegetation Treatment on BLM Lands in Thirteen Western States, and 4) Western Oregon Program-Management of Competing Vegetation.

The attached updated list of approved herbicide formulations and adjuvants provide information that will assist in the correct application of herbicides and adjuvants on public lands. The manufacturer and Environmental Protection Agency (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 one is approved.

For more information or questions regarding formulations and adjuvants approved for use on BLM lands, contact Richard D. Lee, Integrated Pest Management Specialist at (303) 236-1734 or Richard_Lee@blm.gov.
