Field experiment. Soil residues after the application of 0.6 and 6.0 Ib/A triclopyr to non-target vegetation equivalent to 10% and 100% assumed runoff from target vegetation. Data in ppm are the means of two layers. Each composite sample consisted of at least 15 soil cores representing a 0.01 A area.
