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, bicyclonon, 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) 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 a chemical from the quinolinyloxyacetate family of chemicals, bicyclonon, daimuron, dichlormid, dimepiperate, fenclorim, furilazole, isoxadifen-ethyl, mefenpyr-diethyl, naphthalic anhydride (NA), or agriculturally acceptable salts, esters, or mixtures thereof.

6. The composition of claim 5, wherein the chemical from the quinolinyloxyacetate family of chemicals is cloquintocet acid, cloquintocet mexyl, cloquintocet triisopropylamine, or cloquintocet dimethylamine.

7. The composition of claim 5, wherein the chemical from the quinolinyloxyacetate family of chemicals is cloquintocet mexyl.

8. The composition of claim 1, wherein (a) is an agriculturally acceptable benzyl ester of the compound of formula (I) and (b) is cloquintocet mexyl.

9. The composition of claim 1, wherein (a) is an agriculturally acceptable benzyl ester of the compound of formula (I) and (b) is isoxadifen-ethyl.

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

1 to 1;

32.

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

1 to 1;

4.

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

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

14. 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.

15. 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) a compound of the formula (I)

16. The method of claim 15, wherein (a) is a C_i-4 alkyl or benzyl ester of compound (I).

17. The method of claim 16, wherein (a) is a benzyl ester of compound (I).
