Fee Increase Coming September 1, 2026
Beginning September 1, 2026, we will implement a new fee schedule for golf course sample submissions—our first adjustment in 11 years. The fee for in-state golf course samples will increase from $60 to $75 per submission, and the fee for out-of-state golf course samples will increase from $120 to $150 per submission.
About Our Lab
We diagnose and provide management recommendations for turfgrass diseases.
For known pathogens, most samples are diagnosed within 24 hours of receipt (after one night of incubation).
- For home lawn/general turf questions, contact your local NC Cooperative Extension Center first.
- We do not process nematode samples. Submit those to the NCDA&CS Nematode Lab.
- For turfgrass weed identification/control, contact Dr. Navdeep Godara (Extension Turfgrass Weed Specialist).
