Abstract

Provided herein are synergistic herbicidal compositions containing and methods for controlling undesirable vegetation utilizing

• • (a) a compound of formula (I):

or an agriculturally acceptable salt or ester thereof and (b) a cellulose biosynthesis inhibitor, e.g., indaziflam and isoxaben. The methods and compositions described herein provide control of undesirable vegetation, e.g., in direct-seeded, water-seeded and transplanted rice, cereals, wheat, barley, oats, rye, sorghum, corn or 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 synergistic herbicidal composition comprising a herbicidally effective amount of (a) a compound of the formula (I)

2. The composition of claim 1, wherein (b) is indaziflam or isoxaben or an agriculturally acceptable salt thereof.

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

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

5. The composition of claim 1, wherein (a) is a benzyl ester of compound (I).

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

7. The composition of claim 1, wherein the ratio of compound (a) and compound (b) are present in proportions that result in synergistic herbicidal activity.

8. The composition of claim 1, further comprising at least one compound selected from the group consisting of agriculturally acceptable, herbicide safeners, adjuvants, and carriers.

11. The method of claim 8, wherein the undesirable vegetation is controlled in direct-seeded, water-seeded and transplanted 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, industrial vegetation management (IVM) or rights of way (ROW).

9. A method of controlling undesirable vegetation which comprises contacting the vegetation or the locus thereof with or applying to the soil or water to prevent the emergence or growth of vegetation a herbicidally effective amount of (a) a compound of the formula (I)

10. The method of claim 9, wherein (b) is indaziflam or isoxaben or an agriculturally acceptable salt thereof.

12. The method of claim 9, wherein the (a) and (b) are applied to water.

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

14. The method of claim 9, wherein the (a) and (b) are applied pre-emergently to the weed or the crop.

15. The method of claim 9, wherein the (a) and (b) are applied post-emergently to the weed or the crop.

16. The method of claim 9, wherein the undesirable vegetation is controlled in glyphosate-, 5-enolpyruvylshikimate-3-phosphate (EPSP) synthase inhibitor-, glufosinate-, glutamine synthetase inhibitor-, dicamba-, phenoxy auxin-, pyridyloxy auxin-, synthetic auxin-, auxin transport inhibitor-, aryloxyphenoxypropionate-, cyclohexanedione-, phenylpyrazoline-, acetyl CoA carboxylase (ACCase) inhibitor-, imidazolinone-, sulfonylurea-, pyrimidinylthiobenzoate-, triazolopyrimidine-, sulfonylaminocarbonyltriazolinone-, acetolactate synthase (ALS) or acetohydroxy acid synthase (AHAS) inhibitors-, 4-hydroxyphenyl-pyruvate dioxygenase (HPPD) inhibitor-, phytoene desaturase inhibitor-, carotenoid biosynthesis inhibitor-, protoporphyrinogen oxidase (PPO) inhibitor-, cellulose biosynthesis inhibitor-, mitosis inhibitor-, microtubule inhibitor-, very long chain fatty acid inhibitor-, fatty acid and lipid biosynthesis inhibitor-, photosystem I inhibitor-, photosystem II inhibitor-, triazine-, or bromoxynil-tolerant crops.

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