MADISON – Public comments are open through May 3 on a proposed special pesticide registration that would allow use of Stinger® to control weeds in cranberry marshes.

The registration would help cranberry growers control broadleaf weeds including wild bean, pitchfork (beggars tick), ragweeds, asters, clovers, dandelion, narrow-leaved goldenrod, and Joe-pye weed, thistles. The weeds compete with cranberry plants for light, water, and nutrients, reducing yields and providing a breeding ground for plant diseases and insects.

Dow AgroSciences LLC is the manufacturer. The active ingredient is clopyralid. Stinger® is registered for use on other crops, tree plantations, pastures, fallow cropland and some non-crop areas, but not for use on cranberries. It is one of the few herbicides that can be used to control broadleaf weeds after they have emerged from the soil. Its use on cranberries was previously allowed under a special registration that expired Dec. 31, 2012. The department has not received any reports of adverse effects from the previous special registration.

The special registration would allow growers to apply Stinger® twice a year, not to exceed a total of one pint per acre in a year.

The preliminary environmental assessment indicates that the proposed registration will not require a full environmental assessment. This special registration will expire December 31, 2017.

For a copy of the assessment, contact Matt Sunseri, DATCP, P.O. Box 8911, Madison, WI, 53708-8911, 608-224-4547. It is available for review at the department Monday-Friday, 7:45 a.m.-4:30 p.m., 2811 Agriculture Dr., Madison, second floor. Comments received on or before 4:30 p.m., Friday, May 3, will become part of the preliminary environmental assessment record. Send comments to Matt Sunseri by mail at the above address or by email at
matthew.sunseri@wisconsin.gov.

The special registration process allows states to register additional uses of pesticide products 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. Details about the special registration process are available at
