Tordon is 4-ammo-3,5,6-trichloropicolinic acid. Tests in several north central states, using 1/4 oz. of tordon plus 4 oz. of 2,4-D per acre, gave satisfactory control of wild buckwheat (Polygonum convolvulus) and knotweed (P. aviculare) without any evident injury to small grain crops. The best time for applications to control a bread spectrum of weed species is at the early tillering stage.
