The Texas Plant Disease Diagnostic Laboratory, located in College Station, Texas, is a Texas A&M AgriLife Extension Service lab managed by the Department of Plant Pathology and Microbiology at Texas A&M University.
Another resource is the Texas High Plains Plant Disease Diagnostic Laboratory, located in Amarillo, Texas. The THPDDL can be helpful in disease diagnostics of upper plains row crops.
To provide accurate and timely plant disease diagnostic support to AgriLife Extension & Research personnel, Texas Department of Agriculture, the agriculture/green industry and the people of Texas to protect and secure our plant resources and to promote economic competitiveness.
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. In 2002, the TPDDL was called upon to be one of many universities and state labs around the country to participate in the National Plant Diagnostic Network (NPDN) and perspective region, the Southern Plant Diagnostic Network (SPDN). This network seeks 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. Currently, the clinic processes, on average, 2660 samples annually and supports/manages different projects under the direction of Dr. Kevin Ong and Lead Diagnostician, Sheila McBride.
