Use of sarmentine and its analogues with an herbicide, and compositions thereof
View Patent ↗Disclosed herein are methods for modulating (e.g., inhibiting) emergence and growth of monocotyledonous or dicotyledonous plants (e.g., weeds and grasses) using sarmentine and/or a sarmentine analog and a second herbicide. The application of sarmentine and/or a sarmentine analog with a second herbicide to a plant and/or its growth substrate results in a synergistic pre- and/or post-emergence herbicidal activity against the plant. The present method also provides compositions comprising sarmentine and/or a sarmentine analog, in combination with a second herbicide.
1. A method for modulating emergence of annual bluegrass ( Poa annua ), Kentucky bluegrass ( Poa pratensis ), perennial ryegrass ( Lolium perenne ), tall fescue ( Festuca arundinacea ) or creeping bentgrass ( Agrostis stolonifera ), comprising contacting the plant or its growth substrate with:
(a) sarmentine and
(b) amicarbazone;
wherein said sarmentine and amicarbazone have a synergistic herbicidal effect on the plant, and
wherein the concentration of said sarmentine is between 10 and 34 mg/ml and the concentration of said amicarbazone is between 0.04 and 2.8 mg/ml.
2. A synergistic herbicidal composition comprising sarmentine and amicarbazone, wherein the concentration of sarmentine is between 10 and 34 mg/ml, and the concentration of said amicarbazone is between 0.04 and 2.8 mg/ml, and wherein the herbicidal composition modulates the emergence of annual bluegrass ( Poa annua ), Kentucky bluegrass ( Poa pratensis ), perennial ryegrass ( Lolium perenne ), tall fescue ( Festuca arundinacea ) or creeping bentgrass ( Agrostis stolonifera ).
3. The composition of claim 1 , further comprising one or more of a carrier, a surfactant or a diluent.
