example 1

[0139] Spring wheat (TRZAS), winter wheat (TRZAW), durum wheat (TRZDU), spring barley (HORVS), winter barley (HORVW) and common oats (AVESA) containing free quinoxyacetic acid (CQC-a) and compound A safe composition, and measured the phytotoxicity of the safe composition for each crop. In addition, the efficacy of the safening composition was measured against undesired vegetation including feverfew (ANTAR, Chamomile), winter rapeseed (BRSNW, Brassica napus), Chamomile chamomile ( MATIN, light chamomile), and wild mustard (SINAR, wild mustard).

Abstract

Disclosed herein are safened compositions comprising (a) a pyridine carboxylate herbicide or an agriculturally acceptable N-oxide, salt or ester thereof and (b) a quinolinoxy acetate safener or 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) a quinolinoxy acetate safener or agriculturally acceptable salt or ester thereof.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of priority to U.S. Provisional Application No. 62 / 756,163, filed November 6, 2018, which is hereby incorporated by reference in its entirety. technical field [0003] The present disclosure includes safener compositions comprising a carboxypyridine herbicide and a safener, quinoxyacetic acid, and methods of using the safener 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 that are effective in controlling this unwanted growth. [0005] In some cases, although herbicides are effective in controlling unwanted vegetation, they can also have phytotoxic effects on crops and cause damage or...
