Sulfentrazone tank mix partners for weed control in white bean (<i>Phaseolus vulgaris</i> L.)
Bibliographic record
Abstract
Soil-applied broadleaf herbicides for weed management in dry beans (Phaseolus vulgaris L.) in Ontario are limited. Sulfentrazone is an effective broadleaf herbicide with some grass activity and is currently registered for use in soybean and some pulse crops in Canada. If registered for use in dry beans in Ontario, sulfentrazone would provide growers with another mode of action for broadleaf weed control. Five field studies were conducted over a two year period (2014–2015) to determine the tolerance of white beans to sulfentrazone applied pre-emergence (PRE) and if the spectrum of weeds controlled can be expanded by tank-mixing sulfentrazone with a soil-applied grass herbicide. Sulfentrazone (140 and 210 g ai ha −1 ) was mixed with pendimethalin, dimethenamid-p, s-metolachlor or pyroxasulfone. All the tankmixes evaluated provided good control of green foxtail (Setaria viridis L.), pigweeds (Amaranthus powelli L. and A. retroflexus L.), and common lambsquarters (Chenopodium album L.), but only sulfentrazone + pendimethalin had an adequate margin of crop safety. Based on this study, sulfentrazone combined with a grass herbicide provides acceptable control of some grass and broadleaf weed species; however, further research is required to determine if there is an adequate margin of crop safety for weed management in Ontario dry beans.

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.
