Rotstop® C is no longer available

HRD Committee members,

We just found out that Rotstop® C is no longer available for purchase in North America. The decision to remove Rotstop® C from the North America market was made by the manufacturer, Lallemand Plant Care in December 2024. It sounded that it was a business decision.

If you already have the product, you can still use it in the field. But the manufacturer does not sell the product to the North America market at this point. Although you may still find order information about Rotstop® C online, the information is out of date.

With discontinuation of Rotstop® C, we are back to one pesticide – Cellu-Treat® is currently the only pesticide registered and available for use to prevent HRD in Wisconsin.

We are working on posting an article to let the public know about this through the WI DNR Forest Health newsfeed. If you have any questions, please let me know.
