Updated 4/17/2025
The EPA recently proposed revoking most food and feed crop tolerances for chlorpyrifos, with restrictions based on location, application rates, and protections for farmworkers and vulnerable species. As a result, only alfalfa, soybeans, sugar beets, and winter wheat are expected to retain approved food and feed uses in Minnesota. Key deadlines include:
- April 30, 2025: Sale & distribution of certain products must cease, except for export or disposal.
- June 30, 2025: Use of existing stock for food and feed is prohibited, but non-food uses may continue for two years post-cancellation period unless further EPA restrictions are imposed.
The MDA has conditionally registered chlorpyrifos products for 2025. After June 30, 2025, products with old labeling can only be used for non-food purposes, while those with new labeling can still be used for food if they meet updated EPA guidelines. Refer to the EPA’s Chlorpyrifos FAQs page for the affected product lists and updates. For more information, contact us at Pesticide.Registration.MDA@state.mn.us.

The EPA recently proposed revoking most food and feed crop tolerances for chlorpyrifos, with restrictions based on location, application rates, and protections for farmworkers and vulnerable species. As a result, only alfalfa, soybeans, sugar beets, and winter wheat are expected to retain approved food and feed uses in Minnesota. Key deadlines include:
- April 30, 2025: Sale & distribution of certain products must cease, except for export or disposal.
- June 30, 2025: Use of existing stock for food and feed is prohibited, but non-food uses may continue for two years post-cancellation period unless further EPA restrictions are imposed.
The MDA has conditionally registered chlorpyrifos products for 2025. After June 30, 2025, products with old labeling can only be used for non-food purposes, while those with new labeling can still be used for food if they meet updated EPA guidelines. Refer to the EPA’s Chlorpyrifos FAQs page for the affected product lists and updates. For more information, contact us at Pesticide.Registration.MDA@state.mn.us.

The herbicide acetochlor, found in products such as Tripleflex, SureStart, Warrant, and Harness, has increasingly been detected above the state’s chronic water quality standard (≈ 3.6ppb) in many rivers and streams in southern Minnesota. The Minnesota Pollution Control Agency is reviewing acetochlor monitoring data and is considering whether these waterways should be proposed to the EPA to be added to the impaired waters list. This could affect future acetochlor use in the region. If using acetochlor we encourage you to follow the MDA’s Water Quality Best Management Practices (BMPs) for Acetochlor (PDF) to protect water quality.
