As Minnesotans, we champion protecting our communities and natural resources; but harmful chemicals like paraquat continue to pose serious risks to both.
Paraquat is one of the most toxic pesticides still in use in the United States. Even small amounts of exposure could be fatal—and research has linked it to long-term health impacts, including an increased risk of Parkinson’s disease for those living or working near treated areas.
These risks extend beyond those who directly use the pesticide, affecting people who live and work near treated areas. Paraquat also causes lasting environmental damage, remaining in soil for years, impacting groundwater, and harming wildlife. Studies show it can increase mortality rates and reduce reproduction in affected species.
In the 2026 legislative session, a bipartisan bill was proposed that would have prohibited the sale or use of paraquat in Minnesota. If passed, this legislation would have helped protect public health and our environment, as well as align Minnesota with more than 70 countries that have already banned this dangerous chemical. Conservation Minnesota worked to educate Minnesotans about the dangers of paraquat and helped people connect with their legislators in support of the ban. Unfortunately, the bill failed to make it to a final vote.
We’re keeping an eye on this issue and will continue to advocate against the use of paraquat until Minnesota successfully passes a ban.
