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 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.
