Abstract

A safened herbicidal composition for use in rice comprising a herbicidally effective amount of (a) a compound of formula (I):

or an agriculturally acceptable salt or ester thereof and (b) a safener or a compatible herbicide capable of safening such as a chemical from the quinolinyloxyacetate family of chemicals, dicyclonon, daimuron, dimepiperate, fenclorim, furilazole, halosulfuron, isoxadifen-ethyl, mefenpyr-diethyl, naphthalic anhydride (NA), or agriculturally acceptable salts, esters, or mixtures thereof, for use in direct-seeded, water-seeded or transplanted rice.

Claims

1. A safened herbicidal composition for use in rice comprising a herbicidally effective amount of (a) benzyl ester of a compound of the formula (I)

2. The composition of claim 1, wherein (b) is a chemical from the quinolinyloxyacetate family of chemicals, dicyclonon, dichlormid, fenclorim, furilazole, isoxadifen-ethyl, mefenpyr-diethyl, naphthalic anhydride (NA), or agriculturally acceptable salts, esters, or mixtures thereof.

3. The composition of claim 2, wherein the chemical from the quinolinyloxyacetate family of chemicals is cloquintocet acid, cloquintocet mexyl, cloquintocet triisopropylamine, or cloquintocet dimethylamine.

4. The composition of claim 2, wherein the chemical from the quinolinyloxyacetate family of chemicals is cloquintocet mexyl.

5. The composition of claim 1, wherein the weight ratio of (a) to (b) is from 2:

1 to 1;

32.

6. The composition of claim 1, wherein the weight ratio of (a) to (b) is from 1:

1 to 1;

4.

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

8. The composition of claim 1, wherein the rice is direct-seeded, water-seeded, or transplanted paddy.

9. The composition of claim 1, wherein the rice is a glyphosate, glufosinate, dicamba, phenoxy auxin, pyridyloxy auxin, aryloxyphenoxypropionate, acetyl CoA carboxylase (ACCase) inhibitor, imidazolinone, acetolactate synthase (ALS) inhibitor, 4-hydroxyphenyl-pyruvate dioxygenase (HPPD) inhibitor, protoporphyrinogen oxidase (PPO) inhibitor, triazine, or bromoxynil tolerant rice possessing multiple or stacked traits conferring tolerance to multiple chemistries and/or multiple modes of action.

10. A method of controlling undesirable vegetation in rice comprising contacting the vegetation or applying to the soil or water adjacent thereto with a safened herbicidal composition comprising a herbicidally effective amount of (a) benzyl ester of a compound of the formula (I)

11. The method of claim 10, wherein (b) is a chemical from the quinolinyloxyacetate family of chemicals, dicyclonon, dichlormid, fenclorim, furilazole, isoxadifen-ethyl, mefenpyr-diethyl, naphthalic anhydride (NA), or agriculturally acceptable salts, esters, or mixtures thereof.

12. The method of claim 11, wherein the chemical from the quinolinyloxyacetate family of chemicals is cloquintocet acid, cloquintocet mexyl, cloquintocet triisopropylamine, or cloquintocet dimethylamine.

13. The method of claim 11, wherein the chemical from the quinolinyloxyacetate family of chemicals is cloquintocet mexyl.

14. The method of claim 10, wherein the weight ratio of (a) to (b) is from 2:

1 to 1;

32.

15. The method of claim 10, wherein the weight ratio of (a) to (b) is from 1:

1 to 1;

4.

16. The method of claim 10, further comprising an agriculturally acceptable adjuvant or carrier.

17. The method of claim 10, wherein the rice is direct-seeded, water-seeded, or transplanted rice.

18. The method of claim 10, wherein the undesirable vegetation is immature.

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

20. The method of claim 19, wherein the water is part of a flooded rice paddy.

21. The method of claim 10, wherein the (a) and (b) are applied pre-emergently to the weed or the crop.

22. The method of claim 10, wherein the (a) and (b) are applied post-emergently to the weed or the crop.

23. The method of claim 10, wherein the rice is glyphosate, glufosinate, dicamba, phenoxy auxin, pyridyloxy auxin, aryloxyphenoxypropionate, acetyl CoA carboxylase (ACCase) inhibitor, imidazolinone, acetolactate synthase (ALS) inhibitor, 4-hydroxyphenyl-pyruvate dioxygenase (HPPD) inhibitor, protoporphyrinogen oxidase (PPO) inhibitor, triazine, or bromoxynil tolerant.

24. The method of claim 23, wherein the rice possesses multiple or stacked traits conferring tolerance to multiple chemistries and/or multiple modes of action.
