Abstract
The present invention is directed to herbicidal compositions or formulations, and to methods of using such compositions or formulations to kill, or control the growth and proliferation of, unwanted plants. In particular, the present invention is directed to herbicidal compositions or formulations, as well as their methods of use, which comprise N-phosphonomethylglycine or a herbicidal derivative thereof, a pyridine analog or a herbicidal derivative thereof, and optionally one or more suitable surfactants, with N-phosphonomethylglycine being in excess relative to the pyridine analog. Such compositions cause early visual symptoms of treatment and/or enhanced effectiveness or control when applied to the foliage of plants.
