Linuron Products Not Approved on Sand or Loamy Sand Soils

The Agrichemical Bureau at DATCP has recently learned that some growers may be using pesticide products containing the active ingredient (AI) linuron in a manner that is inconsistent with the label.

The two pesticide products registered for use in Wisconsin that contain linuron go by the brand names of Lorox and Linex 4L.  The labeling requirements of these two products specify that they are not to be applied to sites that have sand or loamy sand soils.

DATCP has prepared this notice of finding to distribute to pertinent stakeholders to prevent the potential use of these two products in sand or loamy sand environments.  DATCP would also like to point out that soil restrictions are the result of groundwater threats stated on the product labels.

If you have any questions regarding this matter, please contact DATCP Pesticide Specialist Otto Oemig at (608) 224-4547 or DATCP Investigation & Compliance Section Chief Mark McCloskey at (608) 224-4530.
