Texas Plant Disease Diagnostic Laboratory
The idea for a plant disease diagnostic service at Texas A&M University started in 1956 when Dr. Harlan Smith, the Extension plant pathologist, used it as a way to provide support to Extension personnel and growers/farmers. In 1982, the Texas Plant Disease Diagnostic Laboratory (TPDDL) was formally established, with the appointment of Dr. Larry Barnes as its first director, to provide plant disease diagnostic support to our AgriLife Extension personnel and provide support to clients in the identification of plant disease problems.
This laboratory is a service and effort of the 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.
Phone support/ Client care is available Monday to Friday at 09:00 am – 12:00noon and 1:00pm – 4:00pm. Operation hours for the TPDDL is 8:00 am – 5:00pm Monday-Friday (except on holidays – see Texas A&M AgriLife on-campus holiday schedule) and is located at the Centeq Building at the Texas A&M Research Park in College Station.
