Picloram was injected to different depths in the stems of aspen trees during spring and summer, and the killing effect on the foliage was studied. The efficacy of the applied dosage was correlated better to the surface area and volume of the stem than to the diameter. The young foliage was affected first by the herbicide. Both the xylem and the phloem were involved in the effects that resulted from translocation of the herbicide.
