Please complete a Turf Grass Submission Form
and submit with the sample!
Commercial turf problems (golf courses, sod farms) are handled at the Puyallup clinic.
All other turf problems: Collect samples of turf cores that are at least 4 inches by 4 inches square and 3 inches deep. Include roots, thatch, and soil. Place each turf core into a plastic bag. Sample should be moderately moist but not saturated with water. Please include cores displaying the range of symptoms present at the site.
If insects may be involved, include specimens of the suspect insect according to instructions for submission of insect samples.
