Abstract

Pesticides are frequently employed in banana cultivation to manage insect pests and improve crop yield. However, their persistence in plant tissues and soil can have significant environmental and health implications. This study investigates the persistence of two commonly used insecticides—fipronil and carbosulfan—in banana plants grown on red soil. Residue analysis was performed on soil and plant samples collected at various intervals after pesticide application. The dissipation pattern was studied using gas chromatography and high-performance liquid chromatography. The results demonstrated that both insecticides exhibited a first-order decay pattern. Fipronil showed a longer half-life compared to carbosulfan in both soil and plant tissues, highlighting its higher persistence. The findings underscore the necessity of safe application practices and residue monitoring to ensure food safety and environmental sustainability.
