The Department of Agriculture, Trade and Consumer Protection is accepting comments through March 20 for a proposed special pesticide registration to control weeds in cranberry marshes.
The special registration proposed by DATCP is for Stinger®, which is manufactured by Corteva Agriscience and contains the active ingredient clopyralid.
Stinger® is registered for use on other crops, tree plantations, pastures, fallow cropland and some non-crop areas. The registration would allow for use on cranberries to help growers control broadleaf weeds including wild bean, pitchfork (beggars tick), ragweed, asters, clovers, dandelion, narrow-leaved goldenrod, Joe-pye weed, and thistles. These weeds compete with cranberry plants for light, water, and nutrients, and can reduce yields and berry size. Stinger® would be one of a few herbicides that can be used to control broadleaf weeds after cranberry buds have emerged.
This is the fourth special registration for Stinger® for use on cranberries. The proposed registration expiration is Dec. 31, 2027. No adverse effects of the prior registration were received by DATCP.
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 March 20 will become part of the preliminary environmental assessment record. Copies of the assessment can be requested and comments may be submitted via mail to Alyssa Foss, DATCP, P.O. Box 8911, Madison, WI, 53708 or by email to [email protected].
