Herbicidal compositions containing glyphosate and a pyridine analog

摘要

An aqueous herbicidal composition useful for killing or controlling the growth of unwanted plants comprises :
at least one glyphosate salt predominantly in the form of potassium glyphosate, monoethanolamine glyphosate, or a mixture thereof;
a pyridine analog selected from the group consisting of triclopyr, or a herbicidal derivative thereof; and
at least one surfactant;
wherein the glyphosate salt is present in a concentration less than 320 grams acid equivalent per liter and the glyphosate salt (acid equivalent basis) and the pyridine analog (acid equivalent basis) are present in a weight ratio of at least 8:1, glyphosate being in excess;
and wherein the glyphosate salt and the pyridine analog are present in a weight ratio of from about 8:1 to about 20:1.
