Efficacy of Different Bio-Pesticides against Major Sucking Pests on Brinjal under Field Conditions
Bibliographic record
Abstract
A field study was carried out during 2015 at the experimental area of Entomology Section, Agriculture Research Institute, (ARI) Tando Jam to examine the efficacy of different bio-pesticides against major sucking pests on brinjal under field conditions. Four treatments with three replications were applied. The treatments were: T1=Neem (Azadirachta indica), T2= Tobacco (Nicotiana tabacum), T3= Datura (Datura stramonium) and T4=Control (untreated). Three insect pests were found infesting brinjal including white flies, jassid and mites. Pre-treatment and post-treatment observations were recorded.The results revealed that against white fly, the first spray of Neem extract showed highest reduction percent (82.60%) followed by Tobacco extract (75.95%), Datura extract (73.93%), and lowest for untreated control (11.07%); while in the second spray also Neem extract showed highest effect against white fly (67.53%); followed by Tobacco extract (56.43%), Datura extract (42.25%), and least by untreated plot (5.49%). Against jassid, Neem extract showed highest effect (55.95%) as observed during 1st spray, followed by Tobacco extract (53.38%), Datura o extract (63.11%)and untreated control (8.00%), while after second spray also Neem extract showed highest reduction percent (68.73%) followed by Tobacco extract (55.72%), Datura extract (50.66%) and the lowest was resulted by untreated control (13.90%). Against mites population on brinjal the first spray results showed that Neem extract showed highest effect (96.19%) followed by Tobacco extract (95.75%), Datura extract (86.86%) and least population was recorded in untreated control (9.96%). After second spray, Neem extract showed highest reduction percent (98.33%), followed by Tobacco extract (92.85%), Datura extract (88.93%) and the lowest reduction percent was resulted by untreated control (9.14%)respectively. Neem extract showed its superiority in effect to combat sucking insect pests studied in brinjal, followed by, Tobacco extract, Datura extract and untreated control remained the least.

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.
