The UK Plant Disease Diagnostic Laboratory (PDDL) is an educational resource for Kentucky county Extension agents as they assist their clients in diagnosis and management of plant diseases.  There are two branches of the PDDL, one on the main campus in Lexington and the other at the UK Research and Education Center in Princeton, KY.
