An oilseed coating composition in the form of particles that comprises (i) at least one organic material selected from waxes having a melting point of at least 50°Centigrade and (ii) one or more additives for enhancing seedling vigour and/or seedling growth from oilseeds, wherein the additive(s) is/are selected from inorganic additives and live biological agents. The wax may be carnauba wax, beeswax, chinese wax, shellac wax, spermaceti wax etc., and the particles may have a volume mean diameter of at least 5 micron. Preferably, the organic material is applied to oilseeds in a dry powder form. A method of coating oilseeds with the coating composition comprises obtaining a population of particles of wax, wherein the particles of wax have a pre-determined volume mean diameter, and applying the population of particles to oilseeds. The method may comprise heating the organic material to produce a liquid or gas, cooling the liquid or gas to below its melting point to form a solid, adding the additive(s), and machining the solid organic material into particles for subsequent application. Alternatively, the additives may be added to the heated organic material before cooling.
