Persistence of Early-Season Treatments for Control of Colorado Potato Beetle,<i>Leptinotarsa decemlineata</i>(Say), Attacking Field Tomato
Bibliographic record
Abstract
ABSTRACT The relative persistence of early-season treatments for control of Colorado potato beetle, Leptinotarsa decemlineata (Say) attacking field tomato, Lycopersicon esculentum, in southwestern Ontario, Canada, was compared by laboratory bioassay of field-collected foliage. Both mortality and feeding damage by introduced adult Colorado potato beetle (CPB) were recorded after 72 hours. Four methods of insecticide application (pre-plant foliar [PRF]); post-plant foliar [POF]; pre-plant drench [PRD]; and, planting water [PW]) were compared with commercial control programs. At an arbitrary acceptable threshold for percent mortality/damage reduction of 70%, the order of effectiveness in 1996 was: imidacloprid-PW > imidacloprid-PRD > imidacloprid-POF = cypermethrin-POF, Imidacloprid-PRF did not provide acceptable control of adult CPB. No residues of imidacloprid were detected in ripe tomato fruit following any application or in soil after fall cultivation following PRD-application. Relevance of results to potential CPB-management programs for field tomato is discussed.

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.
