Abstract

fetched live from OpenAlex

Branch and stem cankers caused by Geosmithia morbida associated with mass attack by its primary insect vector (Pityophthorus juglandis) result in thousand cankers disease (TCD) on Juglans and Pterocarya species. Because other fungi and insects can cause visible damage to Juglans nigra, a baseline assessment was performed to document damage types present and to characterize fungi associated with each type. Two branches were collected from trees with visually healthy crowns in TCD-free locations (Indiana and Missouri) and two branches from trees with and without crown symptoms characteristic of TCD within the disease range in Tennessee. In most cases, one of the two branches was girdled at the base 3 to 4 months prior to harvest. Outer bark was peeled from branch subsamples, observed damage characterized, and isolation of fungi from each damage type attempted. Three known pathogens of J. nigra were obtained from different damage types: G. morbida, in Tennessee only; Botryosphaeria dothidea, in Indiana and Tennessee; and Fusarium solani (= members of F. solani species complex), in all three states. The latter two fungi may exacerbate branch dieback and mortality of TCD-affected trees. These results will be of value to plant health specialists monitoring J. nigra in the field and laboratory diagnosticians processing survey samples.

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.
