example 1

[0140] Safer compositions comprising isoxadifen and Compound A were also tested on spring wheat (TRZAS) and spring barley (HORVS), and the phytotoxicity of the safer compositions on each crop was measured. In addition, the efficacy of the safe composition was measured against undesired vegetation including winter rape (BRSNW, Brassica napus), wild chamomile (MATCH, German chamomile), and Russian thistle (SASKR, Saponaria ).

[0141] The results are summarized in Table 1 below.

[0143]

[0144] g / ha = gram per hectare

[0145] TRZAS = common wheat (spring wheat)

[0146] HORVS = barley (spring barley)

[0147] BRSNW = Brassica napus (winter rapeseed)

[0148] MATCH = German chamomile (wild chamomile)

[0149] Saskr = Sarkr (Russian thistle)

example 2

[0151] A safe composition comprising isoxadifen and compound A was also tested on spring barley (HORVS), spring wheat (TRZAS) and winter wheat (TRZAW) and the effect of the safe composition on plants of each crop was measured. toxicity.

[0152] The results are summarized in Table 2 below.

[0158] TRZAW = Wheat (Triticum aestivum) (winter wheat)

example 3

[0160] A safe composition comprising isoxadifen and compound A was also tested on sugar cane (SACOF) and the phytotoxicity of the safe composition was measured.

[0161] The results are summarized in Table 3 below.

Abstract

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

Description

[0001] Cross-references to related applications [0002] This application claims the benefit of priority from U.S. Provisional Application No. 62 / 756,181, filed November 6, 2018, which is incorporated herein by reference in its entirety. Technical field [0003] The present disclosure includes safe compositions comprising a carboxypyridine herbicide and a carboxylate safener, benzoxazole, and 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 controlling this unwanted growth. [0005] In some cases, although herbicides can be effective in controlling undesirable vegetation, they can also have phytotoxic effects on crops and cause d...
