The present invention provides a process for coating a plant propagation material, including a seed, comprising: a.) providing a propagation material, such as seed, to be coated b.) applying to the propagation material a composition comprising at least one reactant having reactive functionality and, optionally, at least one active ingredient and c.) polymerising, crosslinking, curing or otherwise reacting the reactant having reactive functionality on the surface of the plant propagation material to form a coating thereon which may encompass an a.i., when present. The present invention further provides a method for enhancing the safety, quality and/or viability of a plant propagation material, including a seed, comprising providing a coated material having less dust-off.
