Abstract
ABSTRACT Irrigation can influence both turf vigor and playability of putting greens. Anthracnose ( Colletotrichum cereale Manns sensu lato Crouch, Clarke, and Hillman) has become an increasingly destructive disease of annual bluegrass (ABG) [ Poa annua L. f. reptans (Hausskn.) T. Koyama] putting greens, particularly when turf is under stress. This 3‐yr field study evaluated the effects of irrigation quantity (100, 80, 60, and 40% of reference evapotranspiration [ET o ]) on anthracnose severity of ABG mowed daily to 3.2 mm. Severe drought stress (40% ET o ) increased anthracnose severity in 2006, 2007, and 2008. Anthracnose was less severe under 60% ET o irrigation, and irrigating at 80% ET o reduced severity compared to 60% ET o Irrigating at 100% ET o initially reduced anthracnose severity compared to 40% ET o ; however, 100% ET o resulted in similar disease severity later in the 2006 and 2008 seasons. While this response was not observed late in the 2007 season, plots maintained at 100% ET o had turf quality similar to plots irrigated at 40% ET o later in each year due in part to increased algal development. Irrigation to replace 80% ET o typically resulted in the least amount of disease and the best turf quality throughout the trial. Thus, irrigation to minimize drought stress while also avoiding continuous high soil water content is beneficial in reducing anthracnose and maintaining acceptable turf performance.

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 it
