Study of dissipation dynamics and persistent toxicity of selected insecticides in chilli using LCMSMS.

ABSTRACT: Chilli, a globally cultivated and consumed crop is significantly impacted by Thrips parvispinus. The reliance on pesticides could result in residue contamination, adversely affecting quality, leading to export rejections and health risks to consumers. This study evaluated the bioefficacy and persistent toxicity of fipronil and tolfenpyrad against thrips in chilli, and persistence of their residues. Tolfenpyrad demonstrated higher field efficacy (60.94 to 78.53%) against thrips compared to fipronil (37.61 to 58.07%). Residue analysis was performed in leaves and green chilli fruits using LC-MS/MS. Fipronil's efficacy decreased after 5 to 7 days of application, but both fipronil and tolfenpyrad residues remained for 20 and 30 days, respectively. In contrast, the residues in leaves caused pers
