Fuente: WIPO "tomato" The present invention relates to a method of applying a treated plant propagation material onto an underlying substrate, the method comprising steps of: - providing a container comprising a plant propagation material; - providing a separation device configured to separate the plant propagation material into one or more individual plant propagation material units; - releasing the plant propagation material from the container into the separation device to form the one or more individual plant propagation material units; - treating at least part of the one or more individual plant propagation material units during the free-falling inside the separation device with a treatment composition to form one or more treated individual plant propagation material units, wherein the treatment composition comprises at least one inoculant; and - dispensing the one or more individual plant propagation material units onto the underlying substrate, wherein the one or more treated individual plant propagation material units are dispensed by free-falling onto the substrate.
