The Wallingford Swarthmore School District Grounds Department will be treating the SHHS girls lacrosse/hockey field for grub control on Saturday, September 6, 2014 at 11:00am.  The description of the chemical used is as follows:
Carbaryl (1-naphthyl methylcarbamate) is a chemical in the carbamate family used chiefly as an insecticide. It is a white crystalline solid commonly sold under the brand name Sevin, a trademark of the Bayer Company. Union Carbide discovered carbaryl and introduced it commercially in 1958. Bayer purchased Aventis CropScience in 2002, a company that included Union Carbide pesticide operations. It remains the third-most-used insecticide in the United States for home gardens, commercial agriculture, and forestry and rangeland protection. About 11 million kilograms were applied to U.S. farm crops in 1976.[1] As a veterinary drug, it is known as carbaril (INN).
