Abstract

Provided herein are herbicidal compositions containing (a) aminopyralid or an agriculturally acceptable salt or ester thereof and (b) bentazon or an agriculturally acceptable salt thereof. The compositions provide synergistic weed control of undesirable vegetation, e.g., in rice, wheat, barley, oats, rye, sorghum, corn or maize, oilseed rape/canola, vegetables, pastures, grasslands, rangelands, fallowland, turf, tree and vine orchards, aquatics, industrial vegetation management or rights-of-way.

First claim

What is claimed is:

1. A herbicidal composition comprising a synergistic herbicidally effective amount of: (a) aminopyralid, a compound of the formula (I)

or an agriculturally acceptable salt or ester of thereof, and (b) bentazon, a compound of the formula (II)

or an agriculturally acceptable salt of thereof, wherein the ratio of the acid equivalent weight of the compound of formula (I) or agriculturally acceptable salt or ester thereof to the weight of the compound of formula II or agriculturally acceptable salt thereof is from about 1:55 to about 1:10.

2. The composition of claim 1 , wherein (a) is the triisopropanolammonium salt or choline salt of compound (I).

3. The composition of claim 1 , wherein (a) is the compound of formula (I), which is the carboxylic acid.

4. The composition of claim 1 , wherein the (b) is the sodium salt of compound (II).

5. The composition of claim 1 , wherein the ratio is from about 1:45 to about 1:12.

6. The composition of claim 1 , further comprising an agriculturally acceptable adjuvant or carrier.

7. A method of controlling undesirable vegetation which comprises contacting the vegetation or the locus thereof with or applying to soil or water the composition of claim 1 .

8. A method of controlling undesirable vegetation which comprises contacting the vegetation or the locus thereof with or applying to the soil or water a herbicidally effective amount of: (a) aminopyralid, a compound of the formula (I)

or an agriculturally acceptable salt or ester thereof, and (b) bentazon, a compound of the formula (II)

or an agriculturally acceptable salt thereof, wherein the ratio of the acid equivalent weight of the compound of formula (I) or agriculturally acceptable salt or ester thereof to the weight of the compound of formula II or agriculturally acceptable salt thereof is from about 1:55 to about 1:10.

9. The method of claim 8 , wherein the undesirable vegetation is controlled in rice, wheat, barley, oats, rye, sorghum, corn, maize, pastures, grasslands, rangelands, fallowland, turf, tree and vine orchards, industrial vegetation management or rights-of-way.

10. The method of claim 8 , wherein the undesirable vegetation is mature or immature.

11. The method of claim 10 , wherein the (a) and (b) are applied to water.

12. The method of claim 11 , wherein the water is part of a flooded rice paddy.

13. The method of claim 8 , wherein the (a) and (b) are applied pre-emergence.

14. The method of claim 8 , wherein the (a) and (b) are applied post-emergence.

15. The method of claim 8 , wherein the undesirable vegetation is controlled in glyphosate-, glufosinate-, dicamba-, phenoxy auxins-, pyridyloxy auxins-, aryloxyphenoxypropionates-, acetyl CoA carboxylase inhibitors-, imidazolinones-, acetolactate synthase inhibitors-, 4-hydroxyphenyl-pyruvate dioxygenase inhibitors-, protoporphyrinogen oxidase inhibitors-, triazines-, or bromoxynil-tolerant crop.

16. The method of claim 15 , wherein the tolerant crop possesses multiple or stacked traits conferring tolerance to multiple herbicides or inhibitors of multiple modes of action.

17. The method of claim 8 , wherein the undesirable vegetation comprises a herbicide resistant or tolerant weed.

18. The method of claim 17 , wherein the resistant or tolerant weed is a biotype with resistance or tolerance to multiple herbicides, multiple chemical classes, or inhibitors of multiple herbicide modes-of-action.

19. The method of claim 17 , wherein the resistant or tolerant weed is a biotype resistant or tolerant to acetolactate synthase inhibitors, photosystem II inhibitors, acetyl CoA carboxylase inhibitors, synthetic auxins, photosystem I inhibitors, 5-enolpyruvylshikimate-3-phosphate synthase inhibitors, microtubule assembly inhibitors, lipid synthesis inhibitors, protoporphyrinogen oxidase inhibitors, carotenoid biosynthesis inhibitors, very long chain fatty acid inhibitors, phytoene desaturase inhibitors, glutamine synthetase inhibitors, 4-hydroxyphenyl-pyruvate-dioxygenase inhibitors, mitosis inhibitors, cellulose biosynthesis inhibitors, herbicides with multiple modes-of-action, quinclorac, arylaminopropionic acids, difenzoquat, endothall, or organoarsenicals.
