Abstract

Herbicide absorption and translocation patterns were determined following a wet blade method of application to dogfennel stems. Treatment consisted of severing stems with a pruning shear blade containing 5 μl of [14C]-triclopyr or [14C]-clopyralid solution. More than 73 or 82% of applied [14C]-triclopyr or [14C]-clopyralid was absorbed immediately, and uptake increased to more than 90%, 60 min after treatment. Both radiolabeled compounds appeared in the roots as soon as 12 h after treatment. By 48 h, 5 to 7% of the [14C] label was present in the roots, and 7 to 10% was exuded from the roots.
