example 1

[0198] Compositions comprising Compound A and furazone were tested on undesired vegetation species, including spring rape (BRSNN, Brassica napus), wild buckwheat (POLCO, Polygonum volvulus), wild mustard (SINAR, Xinjiang wild rape), Russian Thistle (SASKR, thorns), Kochia (KCHSC, broom), hogweed (AMARE, retroflex), common ash (CHEAL, quinoa), and wild chamomile (MATCH, German chamomile) to determine Efficacy of the compositions against these undesirable vegetation species. The compositions were also tested on spring wheat (TRZAS) and spring barley (HORVS) and the phytotoxicity of the compositions on each crop was measured.

[0199] 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 fatty acid and lipid synthesis inhibitor (FA / LSI) 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 fatty acid and lipid synthesis inhibitor (FA / LSI) 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 from U.S. Provisional Application No. 62 / 756,841, filed November 7, 2018, which is incorporated by reference in its entirety. Technical field [0003] The present disclosure includes compounds containing (a) carboxypyridine herbicides or agriculturally acceptable N-oxides, salts or esters thereof and (b) fatty acid and lipid synthesis inhibitor (FA / LSI) herbicides or agriculturally acceptable N-oxides, salts or esters thereof. Acceptable salt or ester compositions. 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 agen...
