Isocycloseram seed treatment for reducing wireworm populations (<i>Agriotes obscurus</i>) (Coleoptera: Elateridae) and protecting wheat crops in British Columbia
Bibliographic record
Abstract
Wireworms (Coleoptera: Elateridae), the larval stage of several economic click beetle species, have become major cereal crop pests in key agricultural regions of Canada and the United States. In recent trials following minimum tillage practices (Alberta), we determined that isocycloseram, the initial isoxazoline agricultural seed treatment developed, provided exceptional control of cereal crop damage, and significantly reduced neonate and resident wireworm populations of the sugarbeet wireworm, Limonius californicus (Mannerheim). Herein we evaluated isocycloseram in cultivated wheat plots (British Columbia) for control of the dusky wireworm, Agriotes obscurus L., and collectively these studies determined that isocycloseram applied at 5.0 to 7.5 g AI/100 kg seed protected crop stand and yield from these species equal to all currently registered wireworm seed-treatment insecticides (ie, neonicotinoids, diamides, and meta-diamides), and significantly reduced resident and neonate wireworms equal to levels expected from the former industry standard lindane. Abiotic and biotic conditions negatively influencing insecticide performance and ways to mitigate them were also identified. These conditions include soil fertility, moisture, and compaction, and planting after most wireworm feeding in the spring has occurred.

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.
