The disclosure relates to a composition comprising an oil-in- water emulsion, wherein the emulsion comprises oily globules which are each provided with a lamellar liquid crystal coating and are dispersed in an aqueous phase, wherein each oily globule comprises at least one agriculturally active compound selected from the group consisting of fungicides, insecticides, nematocides, miticides, biocides, termiticides, rodenticides, arthropodicides, and herbicides; and is individually coated with a monolamellar or oligolamellar layer comprising: (1) at least one non-ionic lipophilic surface-active agent that has Hydrophilic Lipophilic Balance (HLB) of between 2 and 5 and is selected from the group consisting of optionally ethoxylated mono- or polyalkyl ethers or esters of glycerol or polyglycerol, optionally ethoxylated mono- or polyalkyl ethers or esters of sorbitan, mono- or polyalkyl ethers or esters of pentaerythritol, mono- or polyalkyl ethers or esters of polyoxyethylene, and mono- or polyalkyl ethers or esters of sugars, (2) at least one non-ionic hydrophilic surface-active agent that has HLB of between 8 and 12 and is selected from the group consisting of mono- or polyalkyl ethers or esters of polyethoxylated sorbitan, mono- or polyalkyl ethers or esters of polyoxyethylene, mono- or polyalkyl ethers or esters of polyglycerol, block copolymers of polyoxyethylene with polyoxypropylene or polyoxybutylene, and mono- or polyalkyl ethers or esters of optionally ethoxylated sugars; and (3) at least one ionic surface-active agent that IS selected from the group consisting of (i) alkali metal salts of dicetyl phosphate and dimyristyl phosphate; (ii) alkali metal salts of cholesteryl sulphate and cholesteryl phosphate; (iii) lipoamino acids and their salts; (iv) phospholipids; (v) the mono- and disodium salts of acyl glutamic acids; and (vi) alkyl ether citrates, wherein the oily globules have a mean particle diameter of less than 800 nanometers. |
