example 1

[0148] Compositions comprising Compound A and glyphosate were tested on undesirable vegetation species, including winter rape (BRSNW, Europe), to determine the efficacy of the compositions on these undesirable vegetation species. Rape), wild buckwheat (POLCO, Polygonum cuspidatum), wild mustard (SINAR, Xinjiang wild rape), Russian thistle (SASKR, Saponin), Kochia (KCHSC, broomweed), common grey cabbage (CHEAL, quinoa (Chenopodium album L.), hogweed (AMARE, Amaranth), wild chamomile (MATCH, German chamomile), and 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.

[0149] The results are summarized in Table 1 below.

Abstract

Disclosed herein are compositions comprising (a) a pyridine carboxylate herbicide or an agriculturally acceptable N-oxide, salt, or ester thereof and (b) glyphosate, glufosinate, an agriculturally acceptable salt 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) glyphosate, glufosinate, an agriculturally acceptable salt thereof, or mixtures thereof.

Description

[0001] Related application cross-references [0002] This application claims the benefit of priority to U.S. Provisional Application No. 62 / 756,766, filed November 7, 2018, which is incorporated 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) glyphosate or glufosinate or an agriculturally acceptable N-oxide or ester thereof. with an acceptable salt. The present disclosure also includes 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 gro...
