The Washington State University Puyallup Plant & Insect Diagnostic Laboratory is committed to helping the citizens of Washington State resolve their troubles with plants and insects through accurate problem diagnoses. We also provide applicable management options to a numerous state clientele like commercial growers, pest control operators, home gardeners, consultants, county agents, Master Gardeners, and research personnel.
The laboratory is currently equipped to handle samples from Washington State, particularly western Washington State, and not from other areas of the country.
To achieve an accurate diagnosis of the problems, samples should be accompanied by detailed information about the problem. Go to How to Submit a Sample for additional information. Services will not be provided without payment of diagnostic fees.
