This report is based on trails in 12 northeastern and north central states. The herbicidal combinations consisted of 1 - 3 quarts of tordon (4-ammo-3,5,6-trichloropico-linic acid) and 3 pints of a 2,4-D formulation containing 4 lbs in 3 gallons of water. This was diluted with water to make 25 gallons. An application of 2 quarts of this tordon 101 mixture in 10 gallons of water per acre gave good control of roadside weeds. Norbak, a water-absorbing, particulating agent, was used with the tordon 101 mixture to reduce drift.
