UConn’s Plant Diagnostic Lab services are available for  professional growers, home pest and plant problems, and the green industry.   

Free services: 

  • Image identification
    •   Send images with a description of the host plant, symptoms you’re seeing, and any relevant site history (date of your last soil test, number of affected plants, planting date, etc.) to PlantDiagnosticLab@uconn.edu.
    • Master Gardeners staff plant clinics at every UConn County Extension Office and the Bartlet Arboretum in Stamford. Contact your local UConn Extension Center for more information.

    Fee-based services:

    • The standard fee for all samples submitted to the diagnostic lab is $20.00 per sample. The standard response time is 3-7 business days after the sample has arrived in the lab. Some samples may take longer depending on the pathogen.
    • A few tests require additional fees (i.e. some virus tests).  You will be contacted for approval prior to any tests requiring extra fees.
