example 1

[0172] Compositions comprising compound A and diflufenamide were tested on undesired vegetation species, including winter rape (BRSNW, Brassica napus) to determine the efficacy of the composition against these undesired vegetation species , wild buckwheat (POLCO, buckwheat vine), wild mustard (SINAR, wild mustard), Russian thistle (SASKR, pig hair vegetable), Kochia scoparia (KCHSC, Kochia scoparia), common gray vegetable (CHEAL, quinoa), hogweed ( AMARE (Amaranthus retroflexus), wild chamomile (MATCH, German chamomile), and Canada thistle (CIRAR, field thistle). Compositions were also tested on spring wheat (TRZAS) and spring barley (HORVS), and the phytotoxicity of the compositions on each crop was measured.

[0173] 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) a PDS inhibitor herbicide 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) a PDS inhibitor herbicide or an 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 / 756,788, 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 carboxylate herbicide or an agriculturally acceptable N-oxide, salt, or ester thereof and (b) phytoene dehydrogenase (PDS) Inhibitors or agriculturally acceptable salts or esters thereof. 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 that are effective in controlling this unwanted growth. H...
