Abstract

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

First claim

The invention claimed is:

1. A method for controlling undesirable vegetation comprising 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 a herbicidal composition comprising a synergistically herbicidal 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) saflufenacil (herbicide B), wherein the weight ratio of herbicide A to herbicide B is from 1:0.005 to 1:0.8, and wherein herbicide A and herbicide B are each applied pre-emergence of the undesirable vegetation.

2. The method of claim 1 wherein the undesirable vegetation is controlled in a crop plant selected from the group consisting of 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.

3. The method of claim 1 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, Capsella, Centaurea, Chenopodium, Conyza, Descurainia, Galium, Geranium, Kochia, Matricaria, Papaver, Polygonum, Raphanus, Sinapis, Sisymbrium, Stellaria and Thlaspi.

4. The method of claim 1 wherein the undesirable vegetation is selected from the genera Alopecurus, Avena, Digitaria, Lolium, Setaria, Sorghum, Abutilon, Chenopodium, Galium, Geranium, Papaver, Polygonum and Stellaria.

5. The method of claim 1 wherein the undesirable vegetation is selected from Alopecurus myosuroides, Avena fatua, Digitaria sanguinalis, Lolium multiflorum, Setaria viridis, Sorghum halepense, Abutilon theophrasti, Chenopodium album, Galium aparine, Geranium dissectum, Papaver rhoeas, Polygonum convolvulus and Stellaria media.

6. The method according to claim 1 wherein the undesirable vegetation is a herbicide resistant or tolerant weed species.

7. The method according to claim 1 wherein the herbicide A is applied in an amount of from 10 to 1000 g/ha and the herbicide B is applied in an amount of from 0.5 to 400 g/ha.

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

9. The method of claim 1 , wherein the weight ratio of herbicide A to herbicide B is from 1:0.02 to 1:0.8.

10. The method of claim 1 , 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.

11. The method of claim 1 , further comprising one or more auxiliaries customary in crop protection.
