If you have any questions regarding the specific tests listed below, visit our services tab for the type of sample needed and other details. Packaging and submission information can be found on our forms (D1178, D827, TPDDL1004). Please email plantclinic@tamu.edu or call us at 979-321-5390, if you have any other questions!

Since September 2021, we have utilized the current billing system that requires all new clients to fill out form AG-257 (link to form here).  This should only occur once to set up a customer no. with Texas A&M AgriLife Extension Service. If you have used other AgriLife Extension services, you may have completed this prior – please include your customer no. on the TPDDL form when submitting samples.  Completion of this form AG-257 is required for us to extend our ability to process your sample with necessary procedures for confirmatory diagnosis. The department contact is ‘COURTNEY OVERBY’ and department contact email is ‘courtney.overby@ag.tamu.edu’. For any other inquiries, please email plantclinic@tamu.edu.

We can no longer bill customers without completion of the AG-257 form. IF a check is sent with your sample, then you will not need to fill out the AG-247 form and will not be billed after your report has been sent. We CANNOT begin any work on your submitted sample until we have a customer number in our system. 

If you are a homeowner and/or do not want to provide your identity information (SSN) on the AG-257, you can send a check (pre-pay) made out to Texas AgriLife Extension Service (in blue or black ink only) with your sample. Please note that we are only able to conduct analysis on the specific paid service that is requested and will not be able to pursue further analysis if needed for confirmatory diagnosis.
