Turf diagnostic labs
If you are in any doubt about the identity or cause of a turf problem, we highly recommend the use of a qualified turf diagnostician. Fortunately, there are several good labs around the U.S. who provide this service. Check with your local land grant university and/or county extension agent for information on regional diagnostic laboratories. If none are available, the following labs provide nationwide services for reasonable fees. Labs should be contacted prior to sample shipment for specific preparation and shipping instructions.
