Abstract
Main, D. C., Sanderson, K. R., Fillmore, S. A. E. and Ivany, J. A. 2013. Comparison of synthetic and organic herbicides applied banded for weed control in carrots ( Daucus carota L.). Can. J. Plant Sci. 93: 857–861. The necessity to reduce environmental impact and control the increasing cost of production has many carrot growers seeking new methods of crop management. This research evaluated the potential of applying herbicides in 30-cm bands over the carrot row in combination with between-the-row cultivation to control weeds. Linuron applied in a 30-cm-wide band over the row and linuron applied broadcast provided effective weed control and comparable yield. Clove oil and citrus oil gave slightly better weed control and yield than acetic acid and flaming at the late seeding date. This study demonstrates that acceptable weed control with minimal impact on yield can be achieved with the use of synthetic and organic herbicides applied as a 30-cm-wide band over the row combined with between-row cultivation. This method of weed control provides a 66% reduction in herbicide applied per hectare compared with a broadcast application.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
