Texas Plant Disease Diagnostic Laboratory (TPDDL)

Diagnostic Lab

The Texas Plant Disease Diagnostic Laboratory (TPDDL) was developed to assist clients in the identification of plant disease problems. The lab routinely works with county Extension agents and specialists, 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 recommendations.
