Phyto Diagnostics Company Limited was established in 1996 to provide diagnostic testing services for seed potato growers in Western Canada. Our staff members, former employees of Agriculture and Agri-Food Canada, have research experience in virology, immunology, plant pathology and practical diagnostics.

We are approved by the Canadian Food Inspection Agency (CFIA) to test for: potato viruses, including potato mop top (PMTV); potato spindle tuber viroid (PSTVd); and bacterial ring rot (BRR). The company has expanded to provide diagnostic services for small fruit, tree fruit, greenhouse vegetables, ornamentals and field crops. 

Phyto Diagnostics has a full service monoclonal antibody facility and we produce reagent sets for potato virus diseases and other crops. We produce diagnostic reagents for government laboratories, private laboratories, universities, and other diagnostic test kit producers. Our reagents provide rapid and reliable detection of their targeted plant pathogens.
