Act Next Generation™, Competitor™, Dyne-Amic™, Kinetic™, or
LI-700™) and marker dyes may be used to control invasive
Spartina grass species between June 1, 2010, and October 31,
2010. Properly licensed pesticide applicators who have
obtained coverage under the WSDA national pollutant discharge

Spartina on the saltwater tideflats of Grays Harbor, Hood
Canal, Willapa Bay, Puget Sound, and the north and west sides
of the Olympic Peninsula.

Spartina. These infestations may also be treated, but not
eradicated, by mowing, digging, crushing, or covering.
