Abstract

fetched live from OpenAlex

Abstract The pathogenicity of the ectotrophic root-infecting fungus Gaeumannomyces incrustans on turfgrass Zoysia japonica 'Meyer 51' was examined in greenhouse, growth-chamber, and field assays. Symptoms of root infection (zoysia root rot) were observed in all three studies. In the greenhouse assay, the highest disease severity (percent root surface with lesions (mass necrosis), percent root surface with discoloration, and percent number of leaves with discoloration) was recorded after the longest incubation period (12 weeks). In growth-chamber assays, root-rot severity (percent root surface with lesions and percent root surface with discoloration) was the highest at 18 °C, while little or no injury was observed at 12 and 25 °C. In field assays, patch development was observed in only 3 of 20 inoculated field plots; however, 9 of the 20 plots had ectotrophic mycelium present, and G. incrustans was subsequently recovered from these plots. Gaeumannomyces incrustans is the causal agent of zoysia root rot, as Z. japonica enters and exits seasonal dormancy. Observations of radial expansion are also reported for naturally occurring patches, as well as disease severity ratings for selections of Zoysia spp. from entries in the National Turfgrass Evaluation Program inoculated with G. incrustans.

Teacher imitation

Not 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.
