Cyantraniliprole: Low risk for bees resulting from seed treatment use in oilseed rape
Bibliographic record
Abstract
Cyantraniliprole is the second active ingredient in the anthranilic diamide insecticide class (IRAC Group 28; next to chlorantraniliprole) and the first to control a cross-spectrum of chewing and sucking pests.Cyantraniliprole is a systemic insecticide and mobile via xylem.Oilseed rape seed treatment with cyantraniliprole 625 g/L FS (Lumiposa) at 50 µg a.s./seed provides excellent control of against pests like flea beetles in young emerging rape.The Lumiposa seed treatment product is registered for use in rape in USA and Canada.Cyantraniliprole is characterized by low water solubility (about 0.01 g/L).No increased honeybee mortality was determined in the oral acute toxicity test at maximum water solubility level of cyantraniliprole indicating a low risk potential for bees via systemic plant exposure routes.Also, cyantraniliprole shows rapid decline in soil with DT50 soil values ranging between 13-87 days with no potential for accumulation in soil from repeated uses according to cyantraniliprole labels.Cyantraniliprole residue can be found in guttation droplets of young emerging rape plants, but the cyantraniliprole concentrations in guttation droplets show a rapid decline.No residues of cyantraniliprole metabolites were detected in any rape guttation liquid samples.Worst-case oral risk assessments indicate low risk for bees resulting from the potential cyantraniliprole uptake via guttation liquid.Cyantraniliprole residues or residues of plant metabolites were not detected in pollen or nectar of flowering summer or winter rape or in bee matrices like honey or wax.Honeybee colonies exposed next to flowering winter oilseed rape seed-treated with Lumiposa and honeybee colonies exposed to control field in Germany and France confirmed the safe use of Lumiposa and lack of any effects on honeybee colonies.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
