HERBICIDE COMPOSITIONS COMPRISING ETHOXYLATED LECITHIN
The invention provides herbicidal compositions and methods for weed control with the herbicidal compositions comprising auxin or auxin-like herbicide and ethoxylated lecithin. The undesired vegetation may be controlled using the herbicidal compositions and methods within and without damage to agricultural crops, turf grasses, or ornamental plants. The herbicidal compositions and methods of use disclosed provide for the improvement in post-emergence undesired vegetation control.
1 . A composition comprising quinclorac and its esters or salts and ethoxylated lecithin.
2 . The composition of 2, wherein the composition comprises a weight percent ratio of quinclorac and its esters or salts to the ethoxylated lecithin of 0.8:1.0 to 8.0:1.0.
3 . The composition of claim 3 , wherein the composition comprises a weight percent ratio of quinclorac and its esters or salts to the ethoxylated lecithin of 1.8:1.
4 . The composition of claim 4 , wherein the composition comprises about between about 1% and about 50% of quinclorac and its esters or salts.
5 . The composition of claim 5 , wherein the composition comprises 20% quinclorac and its esters or salts.
6 . The composition of claim 6 , further comprising a crop oil concentrate, a methylated seed oil, or a combination thereof.
7 . The composition of claim 7 , wherein the composition comprises methylated seed oil, wherein the composition has a volume percent between 0.25% and 5.0% of methylated seed oil.
8 . The composition of claim 8 , wherein the composition comprises methylated seed oil, wherein the composition has a volume percent of 1.0% of methylated seed oil.
9 . A method for controlling for controlling undesired vegetation comprising:
preparing a herbicidal composition comprising quinclorac and its esters or salts and ethoxylated lecithin; and
applying a herbicidally effective amount of the herbicidal composition to undesired vegetation.
10 . The method of claim 9 , wherein the herbicidal composition prepared comprises a weight percent ratio of quinclorac and its esters or salts to the ethoxylated lecithin of 0.8:1.0 to 8.0:1.0.
11 . The method of claim 10 , wherein the herbicidal composition prepared comprises a weight percent ratio of quinclorac and its esters or salts to the ethoxylated lecithin of 1.8:1.
12 . The method of claim 11 wherein the herbicidal composition prepared comprises about between about 1% and about 50% of the quinclorac and its esters or salts.
13 . The method of claim 12 , wherein 20% of the herbicidal composition prepared comprises quinclorac and its esters or salts.
14 . The method of claim 13 , wherein the herbicidal composition prepared comprises a crop oil concentrate, a methylated seed oil, or a combination thereof.
15 . The method of claim 14 , wherein the herbicidal composition prepared comprises methylated seed oil, wherein the composition has a volume percent between 0.25% and 5.0% of methylated seed oil.
16 . The method of claim 15 , wherein the herbicidal composition prepared comprises methylated seed oil, wherein the composition has a volume percent of 1.0% of methylated seed oil.
17 . The method of claim 16 , wherein the herbicidal composition is applied in sufficient amounts to supply quinclorac and its esters or salts at about 20 to 100 fl oz per acre.
18 . The method of claim 17 , wherein the herbicidal composition is applied at a rate sufficient to supply 0.1 to 2.0 lb of quinclorac and its esters or salts per acre.
19 . The method of claim 18 , wherein the herbicidal composition is applied after emergence of undesired vegetation.
20 . The method of claim 19 , wherein the undesired vegetation is crabgrass.
