Abstract

fetched live from OpenAlex

Leptosphaerulina leaf blight has been sporadically documented affecting turfgrasses. Recently, a Leptosphaerulina species has been seen on diseased turfgrass samples from New England and New York State. In all cases where Leptosphaerulina has been observed in New England, it has been accompanied by a number of other turf pathogens on highly stressed hosts, so its pathogenic potential has been unclear. The purpose of this study was to identify isolates to species, determine their pathogenicity in the greenhouse, and characterize their fungicide sensitivity in vitro in the event that significant pathogenicity was demonstrated. Microscopic observation of spores and culture characteristics indicated that all examined isolates were Leptosphaerulina australis. The optimum temperature for growth was assessed and the relationship between temperature and sporulation was examined. After repeated experiments utilizing several grass species under a variety of environmental conditions, all four isolates examined were determined to be nonpathogenic. Isolates produced pseudothecia on senescent tissue but infection of live tissue was never observed. The fungicide sensitivity assay demonstrated significant variation among isolates. Based on the results of this study and other observational evidence, it is likely that this species is saprobic on senescent turfgrass leaves but not pathogenic.

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.
