Abstract

fetched live from OpenAlex

Reports of herbicide-resistant weeds continue to rise at an increasing rate, despite current efforts to mitigate this issue. The repeated use of glyphosate resulted in glyphosate-resistant Canada fleabane [Conyza canadensis (L.) Cronq.] populations in Delaware, USA, in 2001, and Ontario, Canada, in 2010. Research has reported rye (Secale cereale L.) cover crops consistently reduced the density and height of Canada fleabane. This research examined if fall-seeded rye can suppress Canada fleabane seedling density and growth, then the interaction(s) of multiple selection pressures should enhance Canada fleabane control which aids farmers in developing integrated weed management strategies. In 2018 and 2019, field studies were conducted to evaluate the interactions between fall-seeded rye cover crops, shallow fall tillage, and spring-applied herbicides. Interactions between selection pressures were observed to have an additive effect on improving weed control; environmental variables, however, had a direct influence on these interactions.

Full frame distilled prediction

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.
