Home | UConn Plant Diagnostic Laboratory

The UConn Plant Diagnostic Laboratory diagnoses plant problems including diseases, insect pests and abiotic causes. Special services offered through the diagnostic lab include extraction and quantification of plant parasitic nematodes from soil or plant material and ELISA testing for plant viruses and other pathogens. Techniques used for diagnosis include visual inspection, digital images, microscopy, incubation, baiting, culture, nematode services, and serological tests. When needed, soil or tissue analysis is recommended through the UConn Soil Testing Laboratory to supplement these analyses. The lab is a member of the National Plant Diagnostic Network. This organization works to prevent the introduction and spread of non-native plant pests and pathogens that have the potential to cause significant damage to plants in agriculture, the green industry, landscapes and natural settings. Diagnosticians and others receive training and information on pest and pathogen identification and pest alerts.
