Abstract

Provided herein are synergistic herbicidal compositions containing and methods utilizing (a) a compound of formula (I):

or an agriculturally acceptable salt or ester thereof and (b) an ACCase inhibitors, including. e.g., clethodim, clodinafop-propargyl, cyhalofop-R-butyl, diclofop-methyl, fenoxaprop-P-ethyl, fluazifop-P-butyl, haloxyfop-R-methyl, metamifop, pinoxaden, profoxydim, quizalofop-P-ethyl, sethoxydim and tralkoxydim, provide synergistic weed control of undesirable vegetation in rice, cereals, wheat, barley, oats, rye, sorghum, corn/maize, sugarcane, sunflower, oilseed rape, canola, sugar beet, soybean, cotton, pineapple, pastures, grasslands, rangelands, fallowland, turf, tree and vine orchards, aquatics, plantation crops, vegetables, industrial vegetation management (IVM) or rights of way (ROW).

Claims

1. A herbicidal composition, comprising:

a herbicidally effective amount of (a) a compound of the formula (I);

2. The composition of claim 1, wherein (a) is a C_1-4 alkyl or benzyl ester of compound (I).

3. The composition of claim 2, wherein (a) is a benzyl ester of compound (I).

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

5. The composition of claim 1, wherein (b) is cyhalofop-R-butyl, or a carboxylic acid, carboxylate salt, or ester thereof, wherein the composition further comprises penoxsulam, bentazon-sodium, triclopyr, bispyribac-sodium, imazamox, benzobicyclon, quinclorac, glyphosate, glufosinate, benfuresate, fentrazamide, indanofan, ipfencarbazone, mefenacet, oxazichlomefone, pretilachlor, propyrisulfuron, pyraclonil, pyriftalid, or pyrimisulfan, or an agriculturally acceptable salt, carboxylic acid, carboxylate salt, or ester thereof, in the composition.

6. A method of controlling undesirable vegetation, comprising the steps of contacting the vegetation or the locus thereof with or applying to the soil or water to prevent the emergence or growth of the vegetation, a herbicidally effective amount of a combination comprising (a) a compound of the formula (I):

7. The method of claim 6, wherein the undesirable vegetation is immature.

8. The method of claim 6, wherein the (a) and (b) are applied to the water.

9. The method of claim 8, wherein the water is part of a flooded rice paddy.

10. The method of claim 6, wherein the (a) and (b) are applied post-emergently and/or post emergently to the undesirable vegetation or crop.

11. The method of claim 6, wherein the undesirable vegetation is controlled in glyphosate-, 5-enolpyruvylshikimate-3-phosphate synthase inhibitor-, glufosinate-, glutamine synthetase inhibitor-, dicamba-, phenoxy auxin-, pyridyloxy auxin-, synthetic auxin-, auxin transport inhibitor-, aryloxyphenoxypropionate-, cyclohexanedione-, phenylpyrazoline-, acetyl CoA carboxylase inhibitor-, imidazolinone-, sulfonylurea-, pyrimidinylthiobenzoate-, triazolopyrimidine-, sulfonylaminocarbonyltriazolinone-, acetolactate synthase or acetohydroxy acid synthase inhibitor-, 4-hydroxyphenyl-pyruvate dioxygenase inhibitor-, phytoene desaturase inhibitor-, carotenoid biosynthesis inhibitor-, protoporphyrinogen oxidase inhibitor-, cellulose biosynthesis inhibitor-, mitosis inhibitor-, microtubule inhibitor-, long chain fatty acid inhibitor-, fatty acid and lipid biosynthesis inhibitor-, photosystem I inhibitor-, photosystem II inhibitor-, triazine-, or bromoxynil-tolerant crops.

12. The method of claim 11, wherein the tolerant crop possesses multiple or stacked traits conferring tolerance to multiple herbicides.

13. The method of claim 6, wherein the undesirable vegetation comprises a herbicide resistant or tolerant plant.

14. The method of claim 13, wherein the resistant or tolerant plant is resistant or tolerant to multiple herbicides.

15. The method of claim 13, wherein the resistant or tolerant plant is resistant or tolerant to acetolactate synthase or acetohydroxy acid synthase inhibitors, photosystem II inhibitors, acetyl CoA carboxylase inhibitors, synthetic auxins, auxin transport inhibitors, photosystem I inhibitors, 5-enolpyruvylshikimate-3-phosphate synthase inhibitors, microtubule assembly inhibitors, fatty acid and lipid synthesis inhibitors, protoporphyrinogen oxidase inhibitors, carotenoid biosynthesis inhibitors, 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.
