Montana Department of Agriculture Pesticide Programs
The Montana Department of Agriculture has the responsibility to ensure that pesticides are available for use and do not pose an unreasonable adverse effect on human health or the environment. In order to fulfill this responsibility, the Montana Department of Agriculture offers a variety of Pesticide Programs, including Pesticide Licensing, Pesticide Training/Certification, Product Registration, Worker Protection Standards, Compliance & Enforcement, Waste Disposal, Container Recycling, and Vertebrate Pests.
Pesticide Disposal and Container Recycling
Montana Department of Agriculture Pesticide Waste Disposal Program
The Montana Department of Agriculture provides free annual pesticide waste disposal events in Kalispell, Plains, Missoula, Polson, Hamilton, Butte, Havre, Great Falls, Lewistown, and Red Lodge (2026). The cost of disposal is free for the first 200 pounds! Visit this site to find a disposal event near you and register.
Montana Department of Agriculture Pesticide Container Recycling Program
The Montana Department of Agriculture provides free pesticide container recycling in an effort to keep pesticide container plastic out of Montana’s landfills. Visit this site to find a collection event near you.

Applicator Information
Pesticide Educational Resources Collaborative (PERC)
PERC aims to protect the public and the environment by minimizing the misuse of pesticides, increasing access to high-quality education for applicators, and managing projects in support of safe pesticide use, thereby ensuring the safety of chemicals in the marketplace. They develop, revise, and update pesticide safety resources to advance the protection of humans, communities, and ecosystems from the risk of pesticide poisonings, illness, and injury.
Pesticide Environmental Stewardship (PES), Center for Integrated Pest Management
PES provides convenient access to information on proper pesticide handling for crop producers, pesticide dealers, commercial/professional applicators, and the general public.
Montana State University Pesticide Education Program
The Montana State University Extension Pesticide Education Program (PEP) is an educational program promoting the proper use of pesticides to protect public health and the environment. This includes coordinating the Montana Private Applicator Training Program, as well as providing educational resources regarding pesticide use, pest management, reading the label, pesticide law, health, safety, and the environment.
Other Pesticide Monitoring Programs
The Montana Pesticide Stewardship Partnership Program is just one of many efforts in the United States to monitor pesticide concentrations in surface water. Below are featured programs in nearby states.
Washington Department of Agriculture
The Washington State Department of Agriculture (WSDA) routinely monitors surface water throughout the state for the presence of pesticides during the typical pesticide use season (March through September). View the WSDA Surface Water Pesticide Monitoring Results Dashboard for the most recent available data.
Oregon Department of Environmental Quality Pesticide Stewardship Partnerships
The Oregon Pesticide Stewardship Partnerships identify potential concerns and improve water quality affected by pesticide use. The partnerships combine local expertise and water quality sampling results to encourage voluntary changes in pesticide use and management practices. Visit the Pesticide Stewardship Partnership Data Viewer for the most recent available data.
California Department of Pesticide Regulation
CDPR scientists sample surface water throughout California to monitor for pesticide residues, identify the any sources of contamination, determine the mechanisms of off-site movement of pesticides to surface water, and develop site-specific mitigation strategies. For more information and access to the most recent available data, visit the following StoryMap: Monitoring Pesticides in Surface Waters of California.
