ABSTRACT
Pathogens employed as antiplant biological weapons are generally used to produce lethal effects in the target plant species. Primarily, targeted species provide food or are of economic value to the area (e.g., grains, fruit). Pathogens can be bacteria, viruses, or fungi. Agents may be in the form of spores, liquid containing active agents, contaminated material (e.g., soil, plant debris), or freeze-dried powders. The agents may also be carried and transmitted by vectors (e.g., flies, aphids, plant lice). There is minimal risk of migration of these pathogens to either humans or animals.
