Phytosanitation

The national and international regulations that control the movement of plant propagating material around the world. The purpose of these regulations is to prevent the spread of dangerous crop parasites to those parts of the world that are still free of them. Phytosanitation can be international, regional, or local. International phytosanitation is usually effective because of border controls. Regional phytosanitation within a country is usually ineffectual because of the lack of border controls. Local phytosanitation involves a single farm, and it can be very effective against soil-borne and seed-borne parasites.
