"News & Issues" piece on the Department of Transportation's (DOT) herbicide spra
"News & Issues" piece on the Department of Transportation's (DOT) herbicide spraying that is done along most of the 8,000 miles of state highways annually to keep the shoulders clear. About 300 miles of state-owned railroad tracks are also sprayed. DOT spokesman Bob LaRoche said the department only sprays within its right of way using two herbicides: Garlon 4 for hardwoods and Vanquish for softwoods. Both of the chemicals have an LD 50 (the dose at which 50 percent of the human population will die) rating lower than table salt, which means a lethal dose of salt would be smaller than a lethal dose of the herbicides. The Pesticide Control Board reviews herbicide spraying practices and at its meeting on July 28 will review DOT's criteria for spraying near sensitive areas.
