Disclosed is a plant supporting formulation which is phytologically 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 mixture incorporates a dissolved gas. 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 [C20:5&omega；3], decosahexaenoic acid [C22:6&omega；3], and ricinoleic acid, and derivatives thereof selected from the group consisting of the C1 to C6 alkyl esters thereof, the glycerolpolyethylene glycol esters thereof, and the reaction product of hydrogenated and unhydrogenated natural oils composed largely of ricinoleic acid based oils, such as castor oil, with ethylene oxide. Preferably at least 95% of the vesicles or microsponges are of a diametrical size of between 50 nm and 5 micrometres. Also disclosed is a method for producing a plant supporting formulation. Further disclosed is a method of treating a plant by administering the plant the formulation.
