Last weekend saw the launch of a pesticide-bacteria spraying campaign that was authorized by Washington State’s Department of Agriculture (WSDA). The areas affected include around 7,000 acres near the Port of Tacoma, 640 acres along Old Pacific Highway SE near the Nisqually River, 600 acres near Gig Harbor, 640 acres near Kent, and 640 acres just north of the Lacey area.
The aim of this program is to kill European and Asian gypsy moths. The bacteria, which is known as Bacillus thuringiensis (Bt) has pesticide properties. In fact, the gene that is used to kill insects in GM crops actually comes from this bacteria.
KOMO reports that the WSDA plans to use a fixed-wing red and white plane to drop the Bt strain Bacillus thuringiensis kurstaki (Btk) pesticide from 250 feet in the air.
