Abstract

Injections with 4-amino-3,5,6-trichloropicolinic acid (picloram), 2-methoxy-3,6-dichlorobenzoic acid (dicamba), and butoxyethanol ester of 2,4,5-trichlorophenoxyacetic acid (2,4,5-T) satisfactorily killed the tops of scarlet oak (Quercus coccinea L.) and white oak (Quercus alba L.) when applied in March or June. Triethylamine salt of 2,4,5-T adequately killed the tops of the oaks in June but not in March. Picloram was the most lethal herbicide used on red maple (Acer rubrum L.), and sprouting was controlled more effectively on all species with picloram than with the other herbicides.
