How to Submit a Suspected Sudden Oak Death/P. Ramorum Blight Sample *

If you have a Sudden Oak Death/Ramorum blight suspect sample you may:

1. Take a sample to a University of Illinois Extension Unit Office and submit the sample for diagnosis via the DDDI system (Distance Diagnostics through Digital Imaging).

   You can obtain extension unit office addresses and maps at http://web.extension.uiuc.edu/cie2/offices/findoffice.cfm. If the sample is still suspect based on DDDI, that sample will be directed to the University of Illinois Plant Clinic for Phytophthora ELISA testing. The fee for SOD samples submitted in this manner is $12.50 payable at the time of sample submission.
   
   OR
   
2. Submit a sample directly to the University of Illinois Plant Clinic with the Elisa fee per sample and a specimen data form.

In all cases mailing costs are at the expense of the client, not the extension office.

All Sudden Oak Death/Ramorum blight samples must meet the following requirements:

1. 20 leaves with suspect symptoms
2. leaflets flat, dry, and placed between dry paper toweling
3. sample packaged in two layers of zip lock plastic bags
4. bags clearly labeled with a permanent marker providing: date, host plant, collector's name, phone number, and specific location of the host.
