Submitting a Digital Sample

Digital Diagnostics: Clients may submit information and high-quality photos via the Plant Pest Diagnostic eNetwork (PPDeN). Digital sample submission typically allows a more timely response. Digital samples also guide the diagnostician when instructing the client how to submit a physical sample of the plant problem. Those wishing to use PPDeN must have a user account, which may be applied for on the PPDeN website. A webinar on using PPDeN is available here, or may be accessed through the PPDeN website by account holders.
