Eight commercial pea fields on Prince Edward Island were sampled in June and July over a 2-year period (1986-87) to determine soil population densities and the incidence of nematodes and fungi associated with root rot of peas. Root lesion nematodes (Pratylenchus spp.) were the dominant endoparasitic nematodes recovered from roots and soil. Low populations of the northern root-knot nematode (Mel...

Historically, root diseases have been a production-limiting problem for the strawberry industry worldwide. Even though this disease is of great economic importance, etiology remains unresolved. However, soilborne fungal pathogens, particularly Pythium and Rhizoctonia spp. implicated as major role players. Presence nematodes in soil favourable environmental conditions also play significant devel...
