Abstract

Herbicidal compositions and methods using a combination of (a) a compound of formula (I):

or an agriculturally acceptable salt or ester thereof and (b) picloram or an agriculturally acceptable salt or ester thereof provide control of undesirable vegetation in,
e.g., rice, wheat, barley, triticale, oats, rye, sorghum, corn or maize, oilseed rape, vegetables, pastures, grasslands, rangelands, fallowland, turf, tree and vine orchards, aquatics, industrial vegetation management or rights-of-way.

Claims

1. A herbicidal composition comprising a synergistic, herbicidally effective amount of (a) a compound of formula (I)

2. The composition of claim 1, wherein no additional herbicidal active ingredients are present.

3. The composition of claim 1, wherein (a) is the methyl ester, triethylammonium (TEA) salt, or potassium salt of the compound of formula (I).

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

5. A method of controlling undesirable vegetation which comprises applying the composition of claim 1.

6. A method of controlling undesirable vegetation which comprises applying a synergistic, herbicidally effective amount of:

(a) a compound of the formula (I)

7. The method of claim 6, wherein the undesirable vegetation is controlled in oilseed rape, wheat, barley, oats, rye, sorghum, corn, maize, rice, pastures, grasslands, rangelands, fallowland, turf, tree and vine orchards, aquatics, industrial vegetation management or rights-of-way.

8. The method of claim 6, wherein the undesirable vegetation is immature.

9. The method of claim 6, wherein (a) and (b) are applied pre-emergently.

10. The method of claim 6, wherein (a) and (b) are applied post-emergently.

11. The method of claim 6, wherein the undesirable vegetation is Setaria faberi Herm. (SETFA), Stellaria media (L.) Vill. (STEME), or Viola tricolor L. (VIOTR).
