Montana Department of Agriculture Announces 2026 Pesticide Disposal Events

HELENA, Mont. – The Montana Department of Agriculture (MDA) is facilitating spring pesticide disposal events during the week of April 7 – 9, 2026, in Kalispell, Plains, and Missoula. Summer disposal events are set for July 7 – 9, 2026, in Polson, Hamilton, and Butte.

These additional pesticide disposal events were made possible through the Montana Pesticide Stewardship Partnership Program (MT PSPP).

The primary objective of the Montana Pesticide Stewardship Partnership Program is to have a lasting impact on the health and water quality of the upper Columbia River Basin (CRB), knowing that protecting the upper basin will also have a sustained positive effect downstream. The Environmental Protection Agency’s (EPA) Columbia River Basin Restoration Funding Assistance Program was started in 2016 to better monitor and make a positive impact in the Columbia River Basin.

Annual pesticide waste collection events have collected nearly 884,000 pounds of pesticide waste from over 1,900 participants since the program’s inception in 1994.

“When it comes the disposal of pesticide products, Montana has limited options,” said Carli Davis of the MDA’s Pesticide Disposal and Container Recycling Programs. “Year after year, this program continues to ensure that waste product is properly disposed of in a manner that is also environmentally friendly.”

The MDA program was designed to assist individuals with disposing of any pesticides that are unusable as originally intended, or cannot be used for any other purpose, in an environmentally responsible way. In effect, the Pesticide and Waste Disposal Program protects Montana’s ecosystems and groundwater, as well as families, pets, livestock and drinking water from potentially hazardous materials.
