Or....(this is a stretch) since the Death Wave draws out the life of something that was meant to be live, maybe it legitimately draws out everything from the living material till it is permanently disabled. In this case, that would mean forcing the plant-life to absorb all the water and minerals in a mad attempt to survive.

This is doubly terrible and fitting for a curse because it effectively turns the affected land barren and thus unable to support life in the future, thus contradicting the flow of nature.
