Welcome to the North American Plant Protection Organization's (NAPPO) Phytosanitary Alert System!

The Phytosanitary Alert System (PAS) provides up-to-date information on plant pest situations of significance to North America. This system is intended to facilitate awareness, detection, prevention and management of exotic pest species in North America. The PAS provides this information in two ways:
1) Official Pest Reports
2) Emerging Pest Alerts

"Official Pest Reports" are provided by National Plant Protection Organizations of Canada, the United States, and Mexico. They serve as official communication from the country of origin and are intended to comply with the International Plant Protection Convention’s Standard on Pest Reporting (ISPM 17: 2002).

"Emerging Pest Alerts" are news items obtained from public sources. They do not serve as official communication from NAPPO. The "Emerging Pest Alerts" is an early warning tool for emerging plant pests that are not present in the North American region. In most cases, information within alerts is not confirmed with the corresponding National Plant Protection Organization. They are provided solely as an early warning to NAPPO countries and should be used with this disclaimer in mind.

Free subscriptions are available for periodic email notifications of new postings to the website.
