dc.description.abstractPlant parasitic nematodes (PPN) are significant pests that parasitize the roots of strawberry plants and cause both direct damage and indirect damage through reduced stress tolerance. Studies were conducted to compare nematode extraction protocols, assess population dynamics of PPN within southern and eastern Ontario, assess 12 strawberry cultivars for their resistance to parasitism by Meloidogyne hapla and Pratylenchus spp. and to assess the efficacy of potential PPN management products. The Baermann pan method extracted more Pratylenchus than the sugar centrifugation method but there was no difference between the two when extracting Meloidogyne from the soil. The nematode genera Meloidogyne and Pratylenchus were present in 42 and 86% of the fields surveyed, respectively. Two cultivars were found to be resistant to M. hapla. The chemical results of the nematicide trial showed some efficacy of fluensulfone but nematode populations were too low to make any other conclusions.en_US
