Abstract

Disclosed herein are compositions comprising (a) a pyridine carboxylate herbicide or an agriculturally acceptable N-oxide, salt, or ester thereof and (b) a microtubule assembly inhibitor (MAI) herbicide, an agriculturally acceptable salt or ester thereof, or mixtures thereof. Also disclosed herein are methods of controlling undesirable vegetation, comprising applying to vegetation or an area adjacent the vegetation or applying in soil or water to control the emergence or growth of vegetation (a) a pyridine carboxylate herbicide or an agriculturally acceptable N-oxide, salt, or ester thereof and (b) a microtubule assembly inhibitor (MAI) herbicide, an agriculturally acceptable salt or ester thereof, or mixtures thereof.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of priority to U.S. Provisional Application No. 62 / 756,719, filed November 7, 2018, which is hereby incorporated by reference in its entirety. technical field [0003] The present disclosure includes compositions comprising (a) a pyridine carboxylic acid herbicide, or an agriculturally acceptable N-oxide, salt, or ester thereof, and (b) a microtubule assembly inhibitor (MAI) herbicide, or an agriculturally acceptable N-oxide, salt, or ester thereof. acceptable salts or esters. The present disclosure also includes methods of using the compositions to control undesired vegetation. Background technique [0004] Many recurring problems in agriculture relate to controlling the growth of undesired vegetation (eg, which may adversely affect the growth of desired vegetation). To help control unwanted vegetation, researchers have produced a variety of chemicals and chemical formulations tha...
