Abstract

Disclosed herein are compositions comprising (a) a pyridine carboxylate herbicide or an agriculturally acceptable N-oxide, salt, or ester thereof and (b) a synthetic auxin herbicide, an auxin transport inhibitor, agriculturally acceptable salts or esters thereof, or combinations 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 synthetic auxin herbicide, an auxin transport inhibitor, agriculturally acceptable salts or esters thereof, or combinations thereof.

First claim

What is claimed is:

1 . A composition, comprising:
(a) a pyridine carboxylate herbicide, wherein the pyridine carboxylate herbicide compound is propargyl 4-amino-3-chloro-5-fluoro-6-(7-fluoro-1H-indol-6-yl)pyridine-2-carboxylate:

(b) a synthetic auxin herbicide, an auxin transport inhibitor, agriculturally acceptable salts or esters thereof, or combinations thereof;
wherein the weight ratio of the pyridine carboxylate herbicide in g ae to the synthetic auxin herbicide or auxin transport inhibitor in g ai is from 1:200 to 20:1.

2 . The composition of claim 1 , wherein the synthetic auxin herbicide is selected from the group consisting of: 2,4-D; 2,4-DB; MCPA; MCPB; 2,3,6-TBA; aminocyclopyrachlor; aminopyralid; benazolin; chloramben; clomeprop; clopyralid; dicamba; dichlorprop; florpyrauxifen; fluroxypyr; halauxifen; mecoprop; picloram; quinclorac; quinmerac; triclopyr; agriculturally acceptable salts and esters thereof; or combinations thereof.

3 . The composition of claim 1 , wherein the auxin transport inhibitor is selected from the group consisting of: chlorflurenol; diflufenzopyr; naptalam; agriculturally acceptable salts or esters thereof; or combinations thereof.

4 . The composition of claim 1 , wherein the weight ratio of the pyridine carboxylate herbicide in g ae to the synthetic auxin herbicide or auxin transport inhibitor in g ai is from 1:100 to 10:1.

5 . The composition of claim 1 , wherein the synthetic auxin herbicide is selected from the group consisting of halauxifen-methyl, florpyrauxifen-benzyl, and a combination thereof.

6 . The composition of claim 1 , further comprising an additional pesticide.

7 . The composition of claim 6 , wherein the additional pesticide is selected from the group consisting of bromoxynil, florasulam, pyroxsulam, agriculturally acceptable salts or esters thereof; and combinations thereof.

8 . The composition of claim 1 , wherein the composition does not include a herbicidal active ingredient in addition to (a) and (b).

9 . A method of controlling undesirable vegetation, comprising applying to vegetation or an area adjacent the vegetation or applying to soil or water to limit the emergence or growth of vegetation a composition, comprising:
(a) a pyridine carboxylate herbicide, wherein the pyridine carboxylate herbicide compound is propargyl 4-amino-3-chloro-5-fluoro-6-(7-fluoro-1H-indol-6-yl)pyridine-2-carboxylate:

(b) a synthetic auxin herbicide, an auxin transport inhibitor, agriculturally acceptable salts or esters thereof, or combinations thereof;
wherein the pyridine carboxylate herbicide is applied in an amount of at least 0.1 g ae/ha;
wherein the synthetic auxin herbicide or auxin transport inhibitor is applied in an amount of at least 1 g ai/ha; and wherein the weight ratio of the pyridine carboxylate herbicide in g ae/ha to the synthetic auxin herbicide or auxin transport inhibitor in g ai/ha is from 1:200 to 20:1.

10 . The method of claim 9 , wherein the pyridine carboxylate herbicide and the synthetic auxin herbicide or auxin transport inhibitor are applied simultaneously.

11 . The method of claim 9 , wherein the synthetic auxin herbicide is selected from the group consisting of: 2,4-D; 2,4-DB; MCPA; MCPB; 2,3,6-TBA; aminocyclopyrachlor; aminopyralid; chloramben; clomeprop; clopyralid; dicamba; dichlorprop; florpyrauxifen; fluroxypyr; halauxifen; mecoprop; picloram; quinclorac; quinmerac; triclopyr; agriculturally acceptable salts and esters thereof; or combinations thereof.

12 . The method of claim 9 , wherein the auxin transport inhibitor is selected from the group consisting of: chlorflurenol; diflufenzopyr; naptalam; agriculturally acceptable salts or esters thereof; or combinations thereof.

13 . The method of claim 9 , wherein the pyridine carboxylate herbicide is provided in amount of 0.1 g ae/ha to 300 g ae/ha.

14 . The method of claim 9 , wherein weight ratio of the pyridine carboxylate herbicide (in g ae/ha) to the synthetic auxin herbicide or auxin transport inhibitor (in g ai/ha) is from 1:100 to 10:1.

15 . The method of claim 9 , further comprising applying an additional pesticide.

16 . The method of claim 9 , wherein the composition does not include a herbicidal active ingredient in addition to (a) and (b).
