  • Take either Hillsborough St. or Western Blvd. to Pullen Road. Follow it to the small traffic circle about a block south of the Belltower.
  • At the small traffic circle, go west on Stinson Dr. until you reach a closed gate.
  • Request a 30-min loading permit at the information booth. Tell the attendant you’re dropping off a sample at the Plant Disease and Insect Clinic.
  • Proceed west on Stinson Dr., which curves several times before dead-ending at Yarbrough Dr. Turn right on Yarbrough.
  • Continue 500 ft. on Yarbrough Dr. and then turn right onto Derieux Pl. which ends in a small parking lot between Gardner and Williams Halls. Look for a 30-min loading space there.
  • Enter the door to Gardner Hall at the north end of this parking lot and follow the signs to the PDIC.
  • If you have a particularly large sample, come and ask us to help you bring it in.
