Overview
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.
Research status
Published in the International Journal of Research and Scientific Innovation; field validation is identified as future work.
Method at a glance
- 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.
What the record supports
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.
