Mailing plant samples from the county extension office or from a regional center is free when using the supplied mailing envelopes and labels.
The Plant Diagnostic Clinic will supply the county extension offices and the state regional centers with FedEx mailers that include a Polyethylene pack and prepaid shipping label. Just call the SDSU Plant Diagnostic Clinic at 688-5545. You can also email at Email for more packs and labels.
When using the prepaid shipping label, you will need to fill in the “From” information section on the shipping label.
Sender’s Name: Please put the Extension office the sample is being mailed from.
This is the only information needed. The rest is already filled in for you.
Call FedEx to schedule a pickup or drop it off at a FedEx store or drop box. The sample will then arrive at the Plant Diagnostic Clinic in 2 days.
NOTE: Consider refrigerating samples that come in on Thurs. and Fri. and then send them in on Mon. to avoid them setting in a warm room over the weekend as they may degrade beyond the point that identification can be made.
