Abstract

fetched live from OpenAlex

Cirsium arvense is perennial broadleaf weed species, reproducing by seeds and creeping roots. It is one of the most feared weeds in all Serbia and as well as in many countries in Europe and in the world. The noxiousness of the C. arvense is due to its creeping root system, every piece of which can give rise to a new plant, and to the numerous seeds which are easily scattered by the wind and which have a great longevity. The leaves of C. arvense vary greatly in the amount of hairiness, degree of lobing and spininess. Canada thistle species has four varieties based on these variations. It is a common weed of small grain crops, row crops, vegetables, orchards, legumes, roadsides, neglected areas, meadows and pastures. It species high adopted on different environmental conditions (type of soil, nutritions, temperature, moisture) and high competitiveness in relation to many crops. Small patches of Canada thistle should be destroyed promptly by digging out the roots, or by covering with heavy mulch paper. In alfalfa and pastures persistant cutting with a scythe or hoe will gradually reduce the thistle. In many crops except cultivation control is possible with application of many herbicides (clopyralid, metsulfuron- methyl, tribenuron-methyl, etc.).

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.
