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.

Herbicidal compositions containing glyphosate and a pyridine analog

Aqueous herbicidal glyphosate compositions are provided, particularly sprayable, ready-to-use (RTU) formulations that are capable of inducing early visually apparent phytotoxic effects while minimizing antagonism to the glyphosate component of the composition and preserving the equally desirable attribute of prolonged control of the treated plants. The compositions combine a glyphosate component and a fatty acid component as a fast symptomology active ingredient and, in one embodiment, are enhanced by the concentration of the fatty acid component utilized and the inclusion of an agronomically acceptable inorganic ammonium salt, preferably ammonium sulfate. In another embodiment, the compositions of the present invention include a nonionic surfactant component comprising certain water-soluble, alkoxylated alcohols.
