A plant supporting formulation which is also suitable for use as a delivery vehicle, or a component of a delivery vehicle, for the delivery of one or more phytologically beneficial substances to a plant, and for enhancing the translocation of such delivered substance(s) in or on the plant, the formulation comprising a micro-emulsion constituted by a dispersion of vesicles or microsponges of a fatty acid based component in an aqueous carrier, the fatty acid based component comprising at least one long chain fatty acid based substance selected from the group consisting of free fatty acids and derivatives of free fatty acids. The dispersion is preferably characterized in that at least 50% of the vesicles or microsponges are of a diametrical size of between 50 nm and 5 micrometer. The dispersion is further also characterized in that the micro-emulsion has a zeta potential of between −25 mV and −60 mV.
A plant supporting formulation which is physiologically beneficial comprising a micro-emulsion constituted by a dispersion of vesicles or microsponges of a fatty acid based component in an aqueous carrier, the fatty acid based component comprising at least one long chain fatty acid based substance selected from the group consisting of oleic acid, linoleic acid, alpha-linolenic acid, gamma-linolenic acid, arachidonic acid, eicosapentaenoic acid [C20:5ω3], decosahexaenoic acid [C22:6ω3], and ricinoleic acid, and derivatives thereof selected from the group consisting of C1 to C5 alkyl esters thereof, glyceropolyethylene glycol esters thereof, and reaction products of hydrogenated and unhydrogenated natural oils composed largely of ricinoleic acid based oils with ethylene oxide and which incorporates a gas dissolved in the fatty acid mixture.
A method for producing a plant supporting formulation comprising the steps of mixing a fatty acid based component with water to obtain a micro-emulsion, and introducing a gas selected from the group consisting of nitrous oxide, carbon oxysulfide and carbon dioxide into the mixture, to impart a size distribution of vesicles or microsponges so that at least 95% of the vesicles or microsponges are of a diametrical size of between 50 nm and 5 micrometer or a zeta potential of between −35 mV and −60 mV to the micro-emulsion, and wherein the fatty acid based component comprises at least one long chain fatty acid based substance selected from the group consisting of oleic acid, linoleic acid, alpha-linolenic acid, gammalinolenic acid, arachidonic acid, eicosapentaenolc acid [C20:5ω3], decosahexaenoic acid [C22:6ω3] ricinoleic acid, and derivatives thereof selected from the group consisting of C1 to C5 alkyl esters thereof, glycerol-polyethylene glycol esters thereof, and reaction products of hydrogenated and unhydrogenated natural oils composed largely of ricinoleic acid based oils with ethylene oxide.
A method for producing a plant supporting formulation comprising the steps of introducing a gas into water, and subsequently mixing a fatty acid based component with said water to obtain a micro-emulsion, wherein said gas is selected from the group consisting of nitrous oxide, carbon oxysulfide and carbon dioxide, to impart a size distribution of vesicles or microsponges so that at least 95% of the vesicles or microsponges are of a diametrical size of between 50 nm and 5 micrometer or a zeta potential of between −35 mV and −60 mV to the micro-emulsion, and wherein the fatty acid based component comprises at least one long chain fatty acid based substance selected from the group consisting of oleic acid, linoleic acid, alpha-linolenic acid, gammalinolenic acid, arachidonic acid, eicosapentaenolc acid [C20:5ω3], decosahexaenoic acid [C22:6ω3] ricinoleic acid, and derivatives thereof selected from the group consisting of C1 to C5 alkyl esters thereof, glycerol-polyethylene glycol esters thereof, and reaction products of hydrogenated and unhydrogenated natural oils composed largely of ricinoleic acid based oils with ethylene oxide.
