Length of residual activity of saflufenacil/dimethenamid-p in soybean (Glycine max)
Bibliographic record
Abstract
Soltani, N., Robinson, D. E, Miller, R. T. and Sikkema, P. H. 2015. Length of residual activity of saflufenacil/dimethenamid-p in soybean (Glycine max). Can. J. Plant Sci. 95: 727-733. A total of six field studies were conducted over a 2-yr period (2009, 2010) at three Ontario locations to determine the length of residual activity of saflufenacil/dimethenamid-p applied preemergence (PRE) for the control of annual weeds in soybean. As the rate of saflufenacil/dimethenamid-p increased from 0 to 980 g a.i. ha-1 the maximum cumulative emergence percentage for common lambsquarters, redroot pigweed and common ragweed decreased. Additionally, as the saflufenacil/dimethenamid-p rate increased from 0 to 980 g a.i. ha-1, the cumulative emergence of common lambsquarters, redroot pigweed and common ragweed slowed down over time. Times to 10% emergence were 1.0, 1.0, 2.1, 3.2, 3.9, 6.6 and >12 wk for common lambsquarters, 1.4, 1.6, 1.8, 2.6, 4.3, >12 and >12 wk for redroot pigweed and 0.8, 1.0, 2.2, 2.7, 3, >12 and >12 wk for common ragweed with saflufenacil/dimethenamid-p applied at 0, 30.625, 61.25, 122.5, 245, 490 and 980 g a.i. ha-1, respectively. Based on these results, saflufenacil/dimethenamid-p applied PRE at the labelled use rate of 245 g a.i. ha-1 can provide as much as 3.9, 4.3 and 3wk of effective control of common lambsquarters, redroot pigweed and common ragweed, respectively in soybean.

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.
