About Widely Prevalent Viruses of the United States
The database is periodically updated by regional coordinators around the country. In addition to providing information for plant pathologists and diagnosticians, the list will be used by APHIS-PPQ to develop a list of viral plant pathogens that are common in each state to help expedite the permitting process for obtaining research isolates. The APHIS-PPQ list will be available on the APHIS website, when it is completed.
A "Widely Prevalent" organism is an organism that:
- might identified by an experienced farmer
- would be able to identified by most experienced county extension agents
- would be able to identified by all experienced diagnosticians at the State level
- would raise no new regulatory concerns at the State or Federal level if it was identified
- is widely distributed in any given five year period in the State where the host plant(s) is grown. It does not have to be widely prevalent every year at every location
