The Texas Plant Disease Diagnostic Laboratory (TPDDL) started 28 years ago to provide plant disease diagnostic support to our AgriLife Extension personnel and to assist clients in the identification of plant disease problems. This laboratory provides a service to the people of Texas by Department of Plant Pathology and Microbiology at Texas A&M University in conjuction with Texas A&M AgriLife Extension Service. This laboratory provides plant disease diagnostic service to AgriLife Extension personnel, homeowners, farmers, greenhouse and nursery producers, landscape contractors, interiorscapers, arborists, consultants, and any other group or individual needing accurate identification of plant disease problems. The TPDDL strives to provide the most accurate and rapid plant disease diagnosis together with recommendations for effective plant disease management.

The Texas Plant Disease Diagnostic Laboratory is one of many university and state labs around the country that are participating in the National Plant Diagnostic Network. The goal of this network is to support a (i) secure regional network for the detection and diagnosis of plant health problems, (ii) extend and support sound public policies, implement rapid and accurate diagnoses, and response strategies, and (iii) provide leadership and training.  The TPDDL is a part of the Southern Plant Diagnostic Network.
