Abstract

The present invention relates to a herbicidal composition comprising pethoxamid. The invention also relates to methods and uses for controlling undesirable vegetation, in particular in crops.

First claim

The invention claimed is:

1. A herbicidal composition comprising a herbicidally effective amount of a) (±)-2-exo-(2-Methylbenzyloxy)-1-methyl-4-isopropyl-7-oxabicyclo[2.2.1]heptane, any of its individual enantiomers or any non-racemic mixture thereof (herbicide A) and (b) pethoxamid (herbicide B), wherein the weight ratio of herbicide A to herbicide B is in the range from 1:0.5 to 1:16.

2. The composition according to claim 1 wherein the herbicide A is (±)-2-exo-(2-Methylbenzyloxy)-1-methyl-4-isopropyl-7-oxabicyclo[2.2.1]heptane.

3. The composition according to claim 1 wherein the herbicide A and herbicide B are each present in an amount sufficient to provide a synergistic herbicidal effect.

4. The composition according to claim 1 wherein the herbicide A and the herbicide B are the only active ingredients.

5. The composition according to claim 1 , further comprising at least one safener D selected from the group consisting of benoxacor (D.1), cloquintocet (D.2), cyometrinil (D.3), cyprosulfamide (D.4), dichlormid (D.5), dicyclonon (D.6), dietholate (D.7), fenchlorazole (D.8), fenclorim (D.9), flurazole (D.10), fluxofenim (D.11), furilazole (D.12), isoxadifen (D.13), mefenpyr (D.14), mephenate (D.15), naphthaleneacetic acid (D.16), naphthalic anhydride (D.17), oxabetrinil (D.18), 4-(dichloroacetyl)-1-oxa-4-azaspiro[4.5]decane (MON4660, CAS Chenopodium, Conyza, Descurainia, Galium, Kochia, Matricaria, Papaver, Polygonum, Raphanus, Sinapis, Sisymbrium, Stellaria and Thlaspi.

6. The composition according to claim 1 , further comprising one or more auxiliaries customary in crop protection.

7. A method for controlling undesirable vegetation which comprises applying to the vegetation or the locus thereof or applying to the soil or water to control the emergence or growth of the undesirable vegetation the composition as claimed in claim 1 .

8. The method according to claim 7 wherein the undesirable vegetation is controlled in crop plants selected from wheat, barley, rye, triticale, oat, corn (maize), sunflower, rice, soybeans, peas, Vicia -beans, Phaseolus -beans, peanuts, oilseed rape, canola, cotton, potato, sugarbeet, sugarcane, turfgrasses and vegetables.

9. The method according to claim 7 wherein the undesirable vegetation is selected from the genera Agropyron, Alopecurus, Apera, Avena, Brachiaria, Bromus, Cynodon, Digitaria, Echinochloa, Eleusine, Ischaemum, Leptochloa, Lolium, Panicum, Phalaris, Poa, Rottboellia, Setaria, Sorghum, Abutilon, Anthemis, Amaranthus, Ambrosia, Brassica, Capsella, Centaurea, Chenopodium, Conyza, Descurainia, Galium, Kochia, Matricaria, Papaver, Polygonum, Raphanus, Sinapis, Sisymbrium, Stellaria and Thlaspi.

10. The method according to claim 7 wherein the undesirable vegetation is selected from the genera Alopecurus, Avena, Lolium, Setaria, Sorghum, Abutilon, Anthemis, Brassica, Chenopodium, Polygonum and Stellaria.

11. The method according to claim 7 wherein the undesirable vegetation is a herbicide resistant or tolerant weed species.

12. The method according to claim 7 wherein the herbicide A and herbicide B are applied before or during the germination of the undesirable vegetation.

13. The method of claim 7 , wherein the herbicide A is (±)-2-exo-(2-Methylbenzyloxy)-1-methyl-4-isopropyl-7-oxabicyclo[2.2.1]heptane.

14. The method of claim 7 , wherein the herbicide A and herbicide B are each present in an amount sufficient to provide a synergistic herbicidal effect.

15. The method of claim 7 , wherein the herbicide A and the herbicide B are the only active ingredients.

16. The method of claim 7 , wherein the composition further comprises at least one safener D selected from the group consisting of benoxacor (D.1), cloquintocet (D.2), cyometrinil (D.3), cyprosulfamide (D.4), dichlormid (D.5), dicyclonon (D.6), dietholate (D.7), fenchlorazole (D.8), fenclorim (D.9), flurazole (D.10), fluxofenim (D.11), furilazole (D.12), isoxadifen (D.13), mefenpyr (D.14), mephenate (D.15), naphthaleneacetic acid (D.16), naphthalic anhydride (D.17), oxabetrinil (D.18), 4-(dichloroacetyl)-1-oxa-4-azaspiro[4.5]decane (MON4660, CAS 71526-07-3) (D.19), 2,2,5-trimethyl-3-(dichloroacetyl)-1,3-oxazolidine (R-29148, CAS 52836-31-4) (D.20), N-(2-Methoxybenzoyl)-4-[(methylaminocarbonyl)amino]benzenesulfonamide (CAS 129531-12-0) (D.21), and agriculturally acceptable salts, esters or amides thereof.

17. The method according to claim 8 wherein the undesirable vegetation is selected from the genera Agropyron, Alopecurus, Apera, Avena, Brachiaria, Bromus, Cynodon, Digitaria, Echinochloa, Eleusine, Ischaemum, Leptochloa, Lolium, Panicum, Phalaris, Poa, Rottboellia, Setaria, Sorghum, Abutilon, Anthemis, Amaranthus, Ambrosia, Brassica, Capsella, Centaurea, Chenopodium, Conyza, Descurainia, Galium, Kochia, Matricaria, Papaver, Polygonum, Raphanus, Sinapis, Sisymbrium, Stellaria and Thlaspi.
