Diseases diagnosed and insects identified at the Pest Diagnostic Clinic, University of Guelph in 2014.

The Pest Diagnostic Clinic, University of Guelph provides plant pest diagnostic services to growers, agri-businesses, provincial and federal governments and homeowners. The clinic receives samples from across Canada but the majority of samples are from Ontario. Services include plant disease diagnosis, plant parasitic nematode identification and enumeration from soil, pathogen detection from soil and water, and insect identification. In 2014, the Pest Diagnostic Clinic received 729 samples representing plants in over 100 genera for disease diagnosis. Samples included greenhouse vegetables, annual and perennial ornamental plants, field crops, berry crops, tree fruits, turfgrass and trees. Over 1,100 soil samples were received for nematode identification and enumeration and 49 samples were received for insect identification. Fifty-five genera of pathogenic fungi and five genera of oomycetes were identified from plant samples submitted. Bacterial plant pathogens, representing 13 species, were identified from 86 plant samples. Nineteen viruses/viroids were identified from 324 plant samples. Ten genera of plant parasitic nematodes were identified from soil samples.
