Herbicidal composition
View Patent ↗A herbicidal composition comprising, in addition to customary inert formulation excipients, as a mixture of at least one acetamide herbicide and a lipophilic additive comprising at least one member selected from the group consisting of C13-C20 fatty acids, C13-C20 fatty alcohols and hydrocarbon fluids.
1. A herbicidal composition, comprising:
a) metolachlor or S-metolachlor;
b) a synergistically active amount of isoparaffinic hydrocarbon fluid, stearic acid or stearyl alcohol; and
c) benoxacor.
2. The herbicidal composition of claim 1 wherein the ratio (wt/wt) of a) to b) is 90:1 to 1.5:1.
3. The herbicidal composition of claim 1 wherein the composition comprises a mixture of the (S) and (R) isomers of metolachlor in the ratio of 50-100% (S) to 50-0% (R).
4. The herbicidal composition of claim 1 wherein the hydrocarbon fluid contains less than 2.0 wt. % aromatic component.
5. The herbicidal composition of claim 1 wherein at least 95 wt. % of the carbon structures of the hydrocarbon fluids fluid have a carbon number distribution of from C13 to C20.
6. The herbicidal composition of claim 1 wherein the hydrocarbon fluid comprises a synthetic iso-paraffin fluid.
7. The herbicidal composition of claim 1 further comprising a co-herbicide.
8. A method of controlling undesired plant growth in the presence of cultivated plants, which comprises treating the cultivated plants, plant parts, seed or the locus thereof with a herbicidally effective amount of the herbicidal composition according to claim 1 .
9. The method according to claim 8 , wherein the cultivated plants are selected from the group consisting of cereals, rape, sugar beet, sugar cane, rice, maize, plantation crops, soybeans and cotton.
10. The method of claim 8 wherein the cultivated plants comprise transgenic plants or herbicidally tolerant plants created by conventional breeding.
11. The method according to claim 8 wherein the herbicidally effective amount of the composition is applied to the soil as a preemergent herbicide.
12. The method of claim 8 , which further comprises treating the cultivated plants, plant parts, seed or the locus thereof with a co-herbicide.
13. The method of claim 12 , which comprises treating the cultivated plants, plant parts, seed or the locus thereof at separate times with the herbicidal composition and the co-herbicide.
