Abstract

A safened herbicidal composition for use in corn (maize) including 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 AD67, benzenesulfonamide, benoxacor, N-(aminocarbonyl)-2-chlorobenzenesulfonamide (2-CBSU), daimuron, dichlormid, dichloroacetamide, dicyclonon, fenchlorazole-ethyl, fenclorim, fluxofenim, furilazole, isoxadifen-ethyl, mefenpyr-diethyl, naphthopyranone, naphthalic anhydride (NA), oxabetrinil, oxime, phenylpyrimidine, phenylurea, a chemical from the quinolinyloxyacetate family of chemicals, or agriculturally acceptable salts, esters, or mixtures thereof. Methods for using the safened herbicidal composition for controlling undesirable vegetation in corn (maize) also are described.

Claims

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

2. The composition of claim 1, wherein (b) is selected from the group consisting of isoxadifen-ethyl, cloquintocet-mexyl, benoxacor, 2-CBSU, daimurom, dichlormid, dicyclonon, fluxofenim, flurilazole, mefenpyr-diethyl, naphthalic anhydride, and oxabetrinil.

3. The composition of claim 1, wherein said (b) comprises isoxadifen-ethyl, and a ratio of the (a) to (b) is from 8:

1 to 1;

8.

4. The composition of claim 1, wherein said (b) comprises cloquintocet-mexyl, and a ratio of the (a) to (b) is from 1:

1 to 1;

4.

5. The composition of claim 1, wherein said (b) comprises benoxacor, 2-CB SU, daimurom, dichlormid, dicyclonon, fluxofenim, flurilazole, mefenpyr-diethyl, naphthalic anhydride, or oxabetrinil, and a ratio of the (a) to (b) is from 1:

1 to 8;

1.

6. A method for controlling the undesirable vegetation in the corn comprising applying to the corn, contacting the vegetation, or area adjacent thereto the composition of claim 1.

7. A method for controlling undesirable vegetation in corn comprising applying to the corn, contacting the undesirable vegetation, or area adjacent thereto a safened herbicidal composition comprising a herbicidally effective amount of (a) the benzyl ester of the compound of the formula (I)

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

9. The method of claim 7, wherein the (a) and (b) are applied pre-emergently to the corn or the undesirable vegetation.

10. The method of claim 7, wherein the (a) and (b) are applied post-emergently to the corn or the undesirable vegetation.

11. The method of claim 7, wherein the (a) is applied pre-emergently or post-emergently to the corn or the undesirable vegetation and the b) is applied as a seed treatment to the corn.

12. The method of claim 7, wherein said (b) is selected from the group consisting of isoxadifen-ethyl, cloquintocet-mexyl, benoxacor, 2-CBSU, daimurom, dichlormid, dicyclonon, fluxofenim, flurilazole, mefenpyr-diethyl, naphthalic anhydride, and oxabetrinil.

13. The method of claim 7, wherein said (b) comprises isoxadifen-ethyl, and a ratio of the (a) to (b) is from 8:

1 to 1;

8.

14. The method of claim 7, wherein said (b) comprises cloquintocet-mexyl, and a ratio of the (a) to (b) is from 1:

1 to 1;

4.

15. The method of claim 7, wherein said (b) comprises benoxacor, 2-CB SU, daimurom, dichlormid, dicyclonon, fluxofenim, flurilazole, mefenpyr-diethyl, naphthalic anhydride, or oxabetrinil, and a ratio of the (a) to (b) is from 1:

1 to 8;

1.

16. The method of claim 7, wherein the safened herbicidal composition further comprises an agriculturally acceptable adjuvant or carrier.

17. The method of claim 7, wherein the corn is glyphosate tolerant, glufosinate tolerant, dicamba tolerant, phenoxy auxin tolerant, pyridyloxy auxin tolerant, aryloxyphenoxypropionate tolerant, acetyl CoA carboxylase (ACCase) inhibitor tolerant, imidazolinone tolerant, acetolactate synthase (ALS) inhibitor tolerant, 4-hydroxyphenyl-pyruvate dioxygenase (HPPD) inhibitor tolerant, protoporphyrinogen oxidase (PPO) inhibitor tolerant, triazine tolerant, or bromoxynil tolerant.
