MADISON – The Wisconsin Department of Agriculture, Trade and Consumer Protection (DATCP) is accepting comments through April 28, 2025 for a proposed special pesticide registration to control weeds in strawberry fields. The special registration proposed by DATCP is for Stinger® and Stinger® HL herbicide, which are manufactured by Corteva AgriSciences, LLC and contain the active ingredient clopyralid.
The proposed special registration for Stinger® and Stinger® HL comes as the pesticide manufacturer transitions through a formulation change of the product. The registration would allow for the use of Stinger® or Stinger® HL to control broadleaf weeds such as dandelion, Canada thistle, bull thistle, and perennial clovers. Strawberry growers would only be allowed to use a single application of either product in a growing season. No other herbicides are registered for use pre-harvest in strawberries to control these weeds.
This is the fifth special registration for Stinger® and Stinger® HL for use on strawberries. The proposed registration will go through December 31, 2029. No reports of adverse effects were received during previous registrations.
The preliminary environmental assessment indicates that the proposed registration will not require a full environmental assessment. Comments received on or before 4:30 p.m. on April 28, 2025 will become part of the preliminary environmental assessment record. Copies of the assessment can be requested, and public comments may be submitted via mail to Alyssa Foss, DATCP, PO Box 8911, Madison, WI, 53708-8911; or by email to alyssa.foss@wisconsin.gov. The assessment is also available for review at the above address between the hours of 7:45 a.m. and 4:30 p.m., Monday through Friday.
More Information
The special registration process allows states to register additional uses of pesticide products other than those listed on their labels, without prior federal approval. It helps growers address local pest problems that cannot be adequately controlled by any available federally registered product. These problems include insect outbreaks, fungal diseases, and grasses and weeds that outcompete crops. For more information, visit https://datcp.wi.gov/Pages/
