    A survey of Helicotylenchus, Paratylenchus, Pratylenchus, and Tylenchorhynchus nematodes in potato fields in Alberta, 2018 and 2019
    (Taylor & Francis, 2021) Robertson, C. J.; Yevtushenko, Dmytro P.; Snowdon, E.; Harding, M. W.
    The prevalence of Helicotylenchus, Paratylenchus, Pratylenchus and Tylenchorhynchus genera of nematodes is not well understood across the prairie provinces of Canada. These nematodes can cause economic damage by feeding on the host crop directly or serve as vectors of plant diseases. While conducting a larger project, nematode populations were quantified in the soil of three commercial potato fields planted with cultivar ‘Russet Burbank’; one in 2018 and two in 2019. The nematodes were extracted from soil samples, identified morphologically, and then quantified as numbers per kg of fresh soil. All four genera were detected in all fields, but the population sizes varied between fields and across time within fields.

    Survey of potato early dying disease complex in Alberta's commercial potato fields, 2021-2022
    (Taylor & Francis, 2023) Rahman, A. U.; Munawar, M.; Konschuh, Michele; Tenuta, M.; Harding, M. W.; Yevtushenko, Dmytro P.
    Potato fields were evaluated for inci dence and severity of early dying disease complex in the growing seasons of 2021 and 2022. Disease sure varied among the fields in both years. Fields taining higher inoculum levels of Verticillium dahliae in the fall soil samples as determined by qPCR of soil samples typically showed more potato early dying (PED) symptom development in the subsequent ing season. The incidence of PED was higher in 2022 than in 2021. Results demonstrated the potential of qPCR evaluation of representative soil samples as an aid for risk prediction activities in potato production systems dealing with PED.
