Abstract

The present invention provides a method for the synergistic control of undesirable plants such as Poa, Polygonum and Setaria which comprises applying to the plants or their locus a synergistically effective amount of a combination of a dinitroaniline compound and an imidazolinone compound. Further provided are synergistic herbicidal compositions comprising dinitroaniline and imidazolinone compounds.

Claims

1. (original) A method for the synergistic control of undesirable Poa, Polygonum or Setaria plants which comprises applying to the locus of said plants, to the foliage or stems of said plants or to the soil or water containing seeds of said plants a synergistically effective amount of a combination of a dinitroaniline compound selected from the group consisting of pendimethalin, trifluralin, benfluralin, butralin, dinitramine, ethalfluralin, fluazinam, fluchloralin, flumetralin, oryzalin and prodiamine;

and an imidazolinone compound selected from the group consisting of imazamox, imazethapyr, imazaquin, imazapic, imazapyr, and mixtures thereof.

2. (original) The method according to claim 1 wherein said plants are Poa annua, Polygonum persicaria or Setaria verticilliata.

3. (currently amended) The method according to claim 2 wherein said plants are Poa annua or Polygonum persicaria.

5. (currently amended) The method according to claim 41 wherein the pendimethalin dinitroaniline compound and imazamox imidazolinone compound are present at a wt/wt ratio of about 20:

3 to 100;

1.

6. (original) The method according to claim 1 wherein the dinitroaniline compound and imidazolinone compound are present at a wt/wt ratio of about 10:

3 to 900;

1.

7. (original) The method according to claim 1 wherein the synergistically effective amount is about 500 g/ha to 4,500 g/ha of a dinitroaniline compound and about 5 g/ha to 150 g/ha of an imidazolinone compound.

11. (new) The method according to claim 5, wherein said plants are Poa annua or Polygonum persicaria.

12. (new) The method according to claim 11, wherein the synergistically effective amount is about 500 g/ha to 4,500 g/ha of the dinitroaniline compound and about 15 g/ha to 100 g/ha of the imidazolinone compound.

4. (canceled)

8. (original) A herbicidal composition for the synergistic control of undesirable Poa, Polygonum or Setaria plants which composition comprises an agriculturally acceptable carrier and a synergistically effective amount of a combination of a dinitroaniline compound selected from the group consisting of pendimethalin, trifluralin, benfluralin, butralin, dinitramine, ethalfluralin, fluazinam, fluchloralin, flumetralin, oryzalin and prodiamine;

and an imidazolinone compound selected from the group consisting of imazamox, imazethapyr, imazaquin, imazapic, imazapyr, and mixtures thereof.

10. (original) The composition according to claim 8 wherein the dinitroaniline compound and imidazolinone compound are present at a wt/wt ratio of about 10:

3 to 900;

1.

9. (canceled)
