Compatibility of Zineb, Dimethoate and Beauveria bassiana (Balsamo) Vuillemin Against Tarnished Plant Bug (Hemiptera: Miridae)
Bibliographic record
Abstract
Experiments were conducted under laboratory and field conditions to assess the effect of the fungicide Zineb (zinc dimethyl-dithiocarbamate) and the insecticide Cygon (dimethoate) on the pathogenicity of the isolate MK 2001 of Beauveria bassiana (Balsamo) Vuillemin, a potential microbial agent for biological control of the tarnished plant bug, Lygus lineolaris (Palisot de Beauvois). The isolate was highly pathogenic to adults yielding an LC50 of 7.2 × 103 conidia/mL at 6 d post treatment and an LT50 of 3.07 d at a concentration of 1 × 108 conidia/mL. Zineb inhibited the in vitro growth of the fungus in Sabouraud's dextrose broth and on Sabouraud's dextrose agar. It had no insecticidal activity against adult L. lineolaris in laboratory bioassays. A field test with caged L. lineolaris adults on lettuce Lactuca sativa L. var. longifolia, at a phenological stage of 50 leaves further demonstrated that Zineb and Dimethoate had no effect on B. bassiana against L. lineolaris. Adult mortality 10 d after application did not differ significantly in treatments with B. bassiana alone from treatments with B. bassiana + Zineb, dimethoate alone, B. bassiana + dimethoate, B. bassiana + Zineb, and B. bassiana + Zineb + dimethoate. No larva was observed in cages treated with B. bassiana alone or in combination with Zineb or dimethoate. On the contrary, 11 larvae/plant were recorded in the untreated cages and 5 larvae/plant in the dimethoate-treated cages.

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.
