Abstract
Chlorantraniliprole is a relatively promising insecticide for controlling insect pests in vegetables. It is commonly used to manage the brinjal fruit and shoot borer (BFSB); however, its residues may pose serious health hazards and have adverse effects on flora and fauna. To address these concerns, insecticide monitoring in eggplant was conducted alongside soil monitoring, as some insecticides can leach into the soil and groundwater. A two-year study was undertaken in India to analyze the risks to the soil ecosystem. Samples were extracted using a modified ethyl acetate-based extraction method, which achieved significant recovery rates of 80.0–84.0% in soil. The risk quotient (RQ) values suggested negligible to low risk to earthworms and arthropods (e.g., Aphidius rhopalosiphi). Therefore, chlorantraniliprole can be recommended for use on brinjal as a low-risk insecticide, with minimal health hazards and environmental impact.
