Abstract
A planting system involving a non-damaging stimulus (3) which is placed in the vicinity of a propagule (2) causes a naturally defensive substance (5) to be produced by the propagule. This substance may exist within an encapsulant (1) for a period of time so that the propagule may have enhanced disease control until it develops sufficiently to fend for itself. In one embodiment a large encapsulant surrounds a potato tuber. This encapsulant may include chitin to cause the release of chitinase through intermediate stimulants such as mRNA and activated carbon to absorb or release particular substances. The encapsulant is bound through the use of pentosan which acts with flaked chitin to achieve an outer casing and further protect the propagule both mechanically and chemically.
