Plant-parasitic nematode populations were analyzed in a total of 152 soil samples from horticultural crops in Alberta in 2014 and 2015. Major genus-level groups of plant-parasitic nematodes found in the survey were, in order of frequency of occurrence: pin, stunt, spiral, lesion, dagger, stubby root, ring, and stem and bulb nematodes. Lesion nematodes, which have significant potential to affect horticultural crops grown in temperate regions, were present in a relatively low percentage of fields, usually at relatively low population densities. Stubby root nematodes were similarly present at relatively low population densities in a low percentage of fields. No root-knot nematodes were found in this survey.
