Abstract

A herbicidal composition containing (a) a compound of formula (I):

or an agriculturally acceptable salt or ester thereof and (b) a sulfonylaminocarbonyltriazone herbicide, or an agriculturally acceptable salt or ester thereof.

Claims

1. A synergistic herbicidal composition comprising a herbicidally effective amount of (a) an agriculturally acceptable benzyl ester of a compound of the formula (I)

2. The composition of claim 1, wherein the sulfonylaminocarbonyltriazone herbicide is flucarbazone, propoxycarbazone, thiencarbazone, or a salt or ester thereof.

3. The composition of claim 1, wherein (b) is flucarbazone or a salt or ester thereof.

4. The composition of claim 1, wherein (b) is propoxycarbazone or a salt or ester thereof.

5. The composition of claim 1, further comprising a herbicide safener.

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

7. The composition of claim 1, which is synergistic as wherein synergy is determined by the Colby equation.

8. A method of controlling undesirable vegetation comprising contacting the undesirable vegetation or applying to the soil or water adjacent thereto with the composition of claim 1.

9. The method of claim 8, wherein the undesirable vegetation is controlled in cereal crops.

10. The method of claim 8, wherein the undesirable vegetation is controlled in direct-seeded rice, water-seeded rice, transplanted rice, wheat, barley, oats, rye, sorghum, corn or maize, soybean, cotton, canola, oilseed rape, pastures, grasslands, rangelands, fallowland, turf, tree and vine orchards, aquatics, or IVM.

11. The method of claim 8, wherein the undesirable vegetation is controlled in glyphosate, glufosinate, dicamba, imidazolinone, 2,4-D, ALS, or ACC'"'"'ase tolerant crops.

12. The method of claim 8, wherein the contacting is a post-emergence application, pre-emergence application, or in-water application to flooded paddy rice or water bodies.

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