Select Agents  

Select agents are biological agents (viruses, bacteria and fungi) known to exist outside the U.S. and thought to pose a severe threat to American agriculture if introduced here. The Plant Protection and Quarantine program has placed nine of these agents on a watch list because of their potential threat to a number of nationally important agronomic crops, including potatoes, rice, soybeans, corn, citrus, and stone fruit.
