Plant and Pest Diagnostic Laboratory
The Purdue University Plant and Pest Diagnostic Laboratory is a central facility for receiving both physical samples and digital images submitted for identification of insects, plants and plant diseases or diagnosis of plant and pest problems. This service is provided for the specialists and county extension educators of the Purdue University Cooperative Extension Service and Purdue University's research faculty, staff, and students as well as for private businesses and citizens of Indiana.
NOTE: Due to construction S. Russell St. is currently closed south of the LSPS building and the Lilly Greenhouses. To reach the PPDL you must access S. Russell St. from State St., not from WIlliams St. from the south. There is a "Road Closed-Local Traffic Only" sign at the entrance to Russell. To get to the PPDL, go around it and turn into the parking area in front of LSPS as usual. Click here for an updated map.
