Population Dynamics and Management of Plant-Parasitic Nematodes in Commercial Strawberry (Fragaria x ananassa) Fields of Southern and Eastern Ontario
Bibliographic record
Abstract
Plant 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.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
