example 1

[0194] Compositions comprising Compound A and benzobicyclone were tested on undesirable vegetation species including curly ear (STEME, chickweed), spring rape (BRSNN, Brassica napus), Brassica juncea ( SETFA, Setaria grandis), Kochia (KCHSC, Broomweed), Italian Ryegrass (LOLMU, Ryegrass multiflora), Barnyardgrass (ECCHG, Echinochloacrus-galli), and Crabgrass (DIGSA, Crabgrass ( Digitaria sanguinalis)) to determine the efficacy of the composition against these undesirable vegetation species.

[0195] 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) an HPPD 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) an HPPD inhibitor herbicide 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 / 756,827, filed November 7, 2018, which is incorporated herein by reference in its entirety. Technical field [0003] The present disclosure includes herbicides comprising (a) a carboxypyridine herbicide or an agriculturally acceptable N-oxide, salt or ester thereof and (b) a 4-hydroxyphenyl-pyruvate dioxygenase (HPPD) inhibitor or compositions of agriculturally acceptable salts or esters thereof. 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 agents that are effective in controllin...
