MADISON, Wis. – The Wisconsin Department of Agriculture, Trade and Consumer Protection (DATCP) is accepting comments through April 19, 2023 for a proposed special pesticide registration to control fungus on ginseng. The special registration proposed by DATCP is for Topsin®, which is manufactured by Nisso America Inc. and United Phosphorus Inc. and contains the active ingredient thiophanate-methyl.
Topsin® is registered for use on other crops, including beans, cucumbers, soybeans, and strawberries. The registration would allow for use on ginseng to help growers control the pests responsible for white mold and disappearing/rusty root rot.
This is the fourth special registration for Topsin® for use on ginseng. The proposed registration expiration is December 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 April 19, 2023 will become part of the preliminary environmental assessment record. Copies of the assessment can be requested and comments can be submitted via mail to Alyssa Foss, DATCP, P.O. Box 8911, Madison, WI, 53708 or by email to alyssa.foss@wisconsin.gov.
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 DATCP's website.
