The Turfgrass Pest Diagnostic Lab provides rapid diagnostics of turfgrass diseases, insects and weeds for commercial turfgrass managers throughout the United States. Our goal is to provide quick and accurate diagnoses and pest control recommendations where needed.

This service is designed for managers of high quality turfgrass such as athletic fields, golf courses and sod farms. The primary difference between our service and other similar services is a rapid turnaround time and the direct involvement of turfgrass diagnostic experts. For this reason, it is always important to call (814-863-0918) prior to sending samples to make sure that the lab is accepting samples.
