Abstract

Safener complexes comprising cloquintocet acid, or a salt thereof, and an amine-containing polymer or oligomer as well as compositions comprising these safener complexes are provided. Also provided are methods of controlling undesirable vegetation in a crop, comprising applying to vegetation or an area adjacent to the vegetation or applying to soil or water to prevent the emergence or growth of the undesirable vegetation in a crop, a safened herbicidal composition comprising a herbicide and a safener complex comprising cloquintocet acid, or a salt thereof, and an amine-containing polymer or oligomer.

First claim

What is claimed is:

1. A composition comprising a safener complex and a pesticide, wherein:
the safener complex comprises cloquintocet acid, or a salt thereof, and an amine-containing polymer or oligomer;
the weight ratio of the cloquintocet acid, or salt thereof, to the amine-containing polymer or oligomer ranges from 1:2 to 10:1; and
the amine-containing polymer or oligomer includes a branched, spherical polyethyleneimine.

2. The composition of claim 1 , wherein the amine-containing polymer or oligomer has an average molecular weight of from 250 to 2,000,000 Daltons.

3. The composition of claim 1 , wherein the amine-containing polymer or oligomer has an average molecular weight of from 500 to 10,000 Daltons.

4. The composition of claim 1 , wherein the polyethyleneimine has a molar ratio of primary amines:secondary amines of from 1:1.25 to 1:0.75.

5. The composition of claim 1 , wherein the polyethyleneimine has a molar ratio of primary amines:tertiary amines of from 1:0.90 to 1:0.40.

6. The composition of claim 1 , wherein the polyethyleneimine has a molar ratio of primary amines:secondary amines:tertiary amines of 1:0.82:0.53, 1:0.91:0.64, or 1:0.94:0.67.

7. The composition of claim 1 , wherein the weight ratio of the cloquintocet acid, or a salt thereof, to the amine-containing polymer or oligomer ranges from 1:1 to 5:1.

8. The composition of claim 1 , wherein the pesticide includes an acetolactate synthase (ALS) inhibitor, an acetyl CoA carboxylase (ACCase) inhibitor, a 4-hydroxyphenylpyruvatedioxygenase (HPPD) inhibitor, a 4-aminopicolinic acid based herbicide, or combinations thereof.

9. The composition of claim 1 , wherein the pesticide is a herbicide that includes pyroxsulam, clodinafop-propargyl, cyhalofop, fluazifop, haloxyfop, iodosulfuron, pinoxaden, pyrasulfotole, fenoxyprop, flucarbazone, flupyrsulfuron, halauxifen, halauxifen-methyl, mesosulfuron, quizalofop, thiencarbazone, or agriculturally acceptable salts or esters thereof, or combinations thereof.

10. The composition of claim 1 , wherein the composition is an emulsifiable concentrate.

11. The composition of claim 1 , wherein the composition is an aqueous spray solution or mixture.

12. A method of controlling undesirable vegetation comprising applying to the vegetation or an area adjacent the vegetation, or applying to the soil to prevent the emergence of the vegetation a herbicidally effective amount of the composition of claim 1 .

13. The method of claim 12 , wherein the undesirable vegetation is controlled in wheat, barley, triticale, rye, teff, oats, corn, sorghum, rice, sugar cane and pasture grasses, or combinations thereof.

14. The method of claim 12 , wherein the undesirable vegetation is selected from the group consisting of wild oat, annual ryegrass, and combinations thereof.

15. A method for preparing a pesticidal composition comprising combining a pesticide and a safener complex comprising cloquintocet acid, or a salt thereof, and an amine-containing polymer or oligomer, wherein the weight ratio of the cloquintocet acid, or salt thereof, to the amine-containing polymer or oligomer ranges from 1:2 to 10:1, and wherein the amine-containing polymer or oligomer includes a branched, spherical polyethyleneimine.
