Abstract

A stabilized herbicidal composition, comprising a fenoxaprop ester herbicide, a salt of 2,4-D, a salt of MCPP-P and a salt of Dicamba, which may also optionally contain additional stabilizers such as triethylamine. Also disclosed is a stabilized herbicidal composition comprising a fenoxaprop ester herbicide in combination with a bromoxynil mixed ester herbicide. The stabilized herbicidal compositions of the present invention may also contain one or more surfactants and/or safeners.

Claims (23)

1. A stabilized herbicidal composition, comprising:

0.5 to about 10 wt % fenoxaprop ester herbicide;

5 to about 40 wt % bromoxynil mixed esters; and

a stabilizer selected from the group consisting of triethanolamine, triethylamine, triisopropanolamine, and combinations thereof.

2. The herbicidal composition of claim 1 , wherein the fenoxaprop ester herbicide is fenoxaprop-p ethyl.

3. The herbicidal composition of claim 1 , wherein the bromoxynil mixed ester includes bromoxynil octanoate, bromoxynil heptanoate or combinations thereof.

4. The herbicidal composition of claim 2 , wherein the herbicidal compounds are present in the ranges of about:

0.5 to about 10 wt fenoxaprop-p ethyl,

5 to about 40 wt % bromoxynil mixed esters, and

0.01 to about 5 wt % triethanolamine.

5. The herbicidal composition of claim 2 , wherein the herbicidal compounds are present in the ranges of about:

4.34 wt % fenoxaprop-p ethyl,

13.44 wt % bromoxynil mixed esters, and

0.1 wt % triethanolamine.

6. The herbicidal composition of claim 1 , wherein the stabilizer is triethanolamine.

7. The herbicidal composition of claim 1 , wherein the stabilizer is triethylamine.

8. The herbicidal composition of claim 1 , wherein the stabilizer is triisopropanolamine.

9. The herbicidal composition of claim 1 , wherein the herbicidal composition is formulated as one selected from the group consisting of a liquid composition, emulsifiable concentrate, suspoemulsion, suspension concentrate, and an aqueous solution.

10. The herbicidal composition of claim 1 , further comprising at least one safener.

11. The herbicidal composition of claim 1 , further comprising at least one surfactant.

12. A method of controlling weeds, comprising: applying the herbicidal composition of claim 1 to turf.

13. A method of controlling crabgrass on turf, comprising: applying the herbicidal composition of claim 1 to turf and/or crabgrass growing in turf.

14. A method of controlling broad leaf weeds on turf, comprising: applying the herbicidal composition of claim 1 to turf and/or broad leaf weeds growing in turf.
