Montana Pesticide Product Registration
The Montana Pesticide Act requires that any pesticide sold, distributed, offered for sale, purchased, given away, used or applied in the state must be registered by the state Department of Agriculture.
Pesticides registered by the state include algaecides, aquatic herbicides, avicides, disinfectants, fungicides, fumigants, herbicides, insecticides, nematocides, predacides, piscicides, rodenticides, repellents and wood preservatives, as well as section 25(b) minimum risk pesticides. Montana does not currently register pesticide devices or adjuvants.
New pesticides may be registered at any time; all renewals are due January 1st of each year. Requirements for new product registrations are electronic copies of the label and SDS (can be submitted via ALSTAR, MTPlants Online Account, or emailed to JBorrego@mt.gov), a signed application form (can be found at the bottom of this page), and a registration fee. Fees can be mailed or paid online.
Updated labels and M/SDSs should be submitted via ALSTAR, MTPlants Online Account, or emailed to JBorrego@mt.gov or mailed to Montana Department of Agriculture on a CD.
We require separate registrations for products with various scents and pet sizes. We do NOT require separate registrations for products with multiple container sizes unless the directions for use vary according to the container.
The EPA defines a pesticide as "Any substance or mixture of substances intended for: preventing, destroying, repelling, or mitigating any pest."
Pests are defined by the EPA as "living organisms that occur when they are not wanted or that cause damage to crops or humans or other animals. Examples include: insects, mice and other animals, unwanted plants (weeds), fungi, microorganisms such as bacteria and viruses, and prions."
Types of Registrations
The majority of pesticides registered in the United States fall under FIFRA Section 3. Each pesticide registration is for a specific, labeled use of a particular formulation which is supported by research data. Before receiving EPA registration, pesticides are required to go through an extensive environmental, health and safety evaluation by the EPA. Once a pesticide has received EPA approval and registration, it can be registered in the state if there is a use for it.
Minimum Risk, Section 25(b)
Section 25(b) pesticides are considered minimum risk pesticides and are exempt from federal registration; however, they still require state registration in Montana. 25(b) products may not be sold in the state prior to being registered, refer to the Montana Requirements for 25(b) Product Registrations for more details. For further background information, refer to FIFRA 25(b) Minimum Risk Products: Notice 2000-6.

Profiles include pesticidal uses, physical and chemical properties, human health effects, environmental effects, efficacy, and applicable standards and regulations. The profiles are intended to help officials, practitioners, and the public to better understand the risks and benefits of the active ingredients in minimum-risk pesticides.
Special Local Need, Section 24(c)
24(c) registrations are for state specific pesticide uses that do not have a Section 3 registration. These registrations require a more extensive review process than Section 3 and 25(b) registrations as they include product uses that have not been reviewed and approved by the EPA. Refer to our 24(c) Guidelines for more details on the application process and requirements. Current 24(c) registrations and labels can be viewed by clicking the button below.
