Effect of Vinasse in the Suppressiveness to Pratylenchus brachyurus in Soybean
Bibliographic record
Abstract
Vinasse, a byproduct result of the process of distillation and fermentation of sugar cane in the ethanol production, stands out for high availability and nutritional alternative source in pest control. The objective of this study was to evaluate the vinasse potential applied to soil, aiming at the control of Pratylenchus brachyurus in soybean crop. The experimental design was a completely randomized factorial (2 × 11), consisting of two forms of application of vinasse (single and divided into two), in eleven concentrations (0%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90% and 100%), with five replications. The soybean plants were inoculated with a suspension of 4,000 eggs/juveniles of P. brachyurus. 60 days after the first application of vinasse, agronomic variables and parasitism were evaluated. The single vinasse application promoted greater growth and root development. Regarding the nematodes parasitism, the application divided was more efficient in the reduction of juveniles in the root and soil, where the concentrations of vinasse enough to reduce the population of 50% (CL50) of the nematodes were 10.22% and 16.64%, respectively. Whereas, for the other variables such as: nematodes per gram of roots (73.97%), eggs in the root (86%) and total nematodes in roots and soil (67.90%), the greatest reduction was observed in the 20% concentration of vinasse. Therefore, vinasse shows potential as a nematicide, as well as excellent organic fertilizer.

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.
