EPA Cancels Pesticide Registrations Over Unpaid Fees
14 November 2026, Washington, US: The U.S. Environmental Protection Agency has issued a cancellation order affecting a wide range of pesticide product registrations held by major agrochemical manufacturers. The order covers two separate groups of registrations: products that registrants voluntarily asked EPA to cancel, and products that lapsed because the registrant did not pay the required annual maintenance fee. It is filed under docket number EPA-HQ-OPP-2026-4192 (FRL-13655-01-OCSPP) and is scheduled for publication in the Federal Register on November 13, 2026, taking effect on that publication date.
EPA acted under section 6(f) of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), codified at 7 U.S.C. 136d(f), which allows the agency to cancel a registration by order and without a hearing. The nonpayment cancellations stem from FIFRA section 4(i)(5), 7 U.S.C. 136a-1(i)(5), which requires most pesticide registrants to pay an annual maintenance fee by January 15 each year to keep a registration active. Registrants who miss that deadline risk losing the registration entirely. EPA’s Regulatory and Information Services Division, through staff contact Jennifer Drobish, is handling inquiries on the order.
Major manufacturers named in the order
The cancellations touch registrations held by many of the industry’s largest companies alongside smaller formulators and specialty registrants. Companies named include Syngenta Crop Protection, Nufarm Americas, BASF Agricultural Solutions US, FMC Corporation, Winfield Solutions, AMVAC Chemical Corporation, Helena Agri-Enterprises, Liphatech, Clarke Mosquito Control Products, Gowan Company, Elanco US, Drexel Chemical Company, Valent U.S.A., Pyxis Regulatory Consulting (acting as agent for Tessenderlo Kerley), Makhteshim Agan of North America (doing business as Adama), and Kop-Coat.
Herbicides, insecticides and fungicides on the list
The affected registrations span herbicides, insecticides, fungicides, miticides and even wood preservatives, including several long-marketed branded products. A sample of the specific registrations named in the voluntary-cancellation portion of the order:
| Company | Product | Active ingredient / type |
|---|---|---|
| Syngenta Crop Protection | Vanquish Herbicide | Dicamba |
| Syngenta Crop Protection | Karate Insecticide with Zeon Technology | Lambda-cyhalothrin |
| Syngenta Crop Protection | Touchdown Total | Glyphosate |

The list also includes narrower, single-state registrations such as residential lawn-care insecticides and niche uses, including wood-treatment and sapstain-control products sold by Kop-Coat, and several Nufarm-branded selective herbicides marketed under the Riverdale label.
Registrants whose products were cancelled for nonpayment can avoid the same outcome in future years by submitting the required maintenance fee and supporting data to EPA’s Office of Pesticide Programs ahead of the January 15 deadline each year. The cancellation applies strictly to the specific registration numbers listed in the order’s tables; other registrations held by the same companies are unaffected.
