Bioefficacy of Marigold (Tagetes spp.) Oil as Biopesticide Against Eggplant Fruit and Shoot Borer

Cyrus C. Bautista · Jolina A. Enardecido, RAgr · Karlo C. Balabat

A laboratory study assessed marigold oil-emulsion for phytotoxicity on young eggplant leaves and activity against eggplant fruit and shoot borer larvae. The paper reports a concentration- and exposure-time relationship and calls for field validation before regular-use recommendations.

Published in the International Journal of Research and Scientific Innovation; field validation is identified as future work.

  • Completely randomized design with a leaf phytotoxicity experiment and a laboratory larval bioassay.
  • The bioassay compared three study concentrations and recorded observations at one, two, and three hours after treatment.
  • The paper reports 88.89% larval mortality at the highest study concentration after three hours; it says further field work is needed.

The article reports no observed phytotoxicity on the treated young leaves and describes higher larval mortality at higher concentrations. These are the paper’s laboratory findings, not product directions or a claim of regulatory approval.

Research themes

An evolving agenda.

These themes are areas of interest, not a claim that every topic has a completed study.

Botanical crop protection

Research into plant-derived approaches to crop protection, documented through the marigold and chrysanthemum studies.

Agricultural biotechnology

Practical research and enterprise ideas that connect biological science with agricultural needs.

Biological crop protection

Exploring research pathways that can be assessed through laboratory and field validation.

Sustainable agricultural inputs

A portfolio interest focused on useful inputs, responsible evidence, and farmer-centered application.
