In the Spring of 2012, OISC conducted a small study to examine the environmental fate of Imprelis Herbicide residues in treated soils and impacted plant tissues. A copy of that report can be found HERE. In consideration of the findings in that report, OISC is recommending that all property owners and turf and ornamental professionals use caution if replanting known sensitive plant species back into Imprelis treated soil this season.
