[0359] Compositions comprising Compound A and Imazamox were tested to determine their efficacy against undesirable vegetation species including winter rape (BRSNW, Brassica napus), wild buckwheat (POLCO, Vol. Stem polygonum), wild mustard (SINAR, Xinjiang wild rape), Russian thistle (SASKR, Saponaria thorn), Kochia (KCHSC, broomweed), common grey cabbage (CHEAL, Chenopodium album L.), pig Grass (AMARE, Amaranth), Wild Chamomile (MATCH, German Chamomile), and Canadian Canada Thistle (CIRAR, Field Thistle). The compositions were also tested on spring wheat (TRZAS) and spring barley (HORVS) and the phytotoxicity of the compositions was measured for each crop.

Abstract

Disclosed herein are compositions comprising (a) a pyridine carboxylate herbicide or an agriculturally acceptable N-oxide, salt, or ester thereof and (b) an acetolactate synthase (ALS) inhibitor or an agriculturally acceptable salt or ester 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) an ALS inhibitor or an agriculturally acceptable salt or ester thereof.

Description

[0001] Related application cross-references [0002] This application claims the benefit of priority to U.S. Provisional Application No. 62 / 756,745, filed November 7, 2018, which is incorporated herein by reference in its entirety. Technical field [0003] The present disclosure includes compositions comprising (a) a picolinate herbicide, or an agriculturally acceptable N-oxide, salt or ester thereof, and (b) an acetolactate synthase (ALS) inhibitor, or Agriculturally acceptable salts or esters thereof. The present disclosure also relates to methods of using the compositions to control undesirable vegetation. Background technique [0004] Many recurring problems in agriculture involve controlling the growth of undesirable vegetation that may, for example, negatively affect the growth of desirable vegetation. To help control unwanted vegetation, researchers have produced a variety of chemicals and chemical formulations that are effective in controlling this unwanted growth....
