How to Submit a Suspected Soybean Rust Sample

Currently, the University of Illinois Plant Clinic cannot receive samples from states other than Illinois. Do not send us samples from other states. All packages received from other states will be destroyed on receipt. Specific Federal Permit instructions must be followed for interstate movement of samples containing plant pests (insects and pathogens) and soil potentially containing plant pests. Please call the Plant Clinic for further details.

If you have a soybean rust suspect sample you may:

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 at no fee other than your mailing costs.

OR
Submit a sample directly to the University of Illinois Plant Clinic with the General Diagnosis fee per sample and a specimen data form.

All soybean rust suspect samples must meet the following requirements:

20 leaflets with suspect symptoms
leaflets flat, dry, and placed between dry paper toweling
sample packaged in two layers of zip lock plastic bags
bags clearly labeled with a permanent marker providing: date, host plant, collector's name, phone number, appropriate supervisor/DSM contact information, collection location within the field, location of the field, county, township & section, and nearest intersection. GPS information is helpful if available.
