Mark from Sterling, Va writes

Have a field of vinca that is Japanese stiltgrass is invading, does Trimec 992 work on it?

Will Trimec 992 be effective stopping the Japanese stiltgrass applied as a pre emergent (early spring) and not kill the vinca.

Answer:

Trimec 992 Broadleaf Herbicide is not labeled to control Japanese stiltgrass nor does it have any preventative properties. If applied when it is too cold it simply will not work. Dimension 2EW Herbicide is labeled to prevent Japanese stilgrass (Mary's grass) while also being safe for ornamentals such as vinca
