Distribution and dissipation of deltamethrin, dimethomorph, imidacloprid, mepanipyrim, and metalaxyl applied to chili peppers

Field trials were carried out to investigate the dissipation rates of pesticides as well as to measure the terminal residues in chili peppers. Deltamethrin, dimethomorph, imidacloprid, mepanipyrim, and metalaxyl were applied to chili peppers 15 days prior to harvest. Chili pepper samples were collec...

Description
Summary:Field trials were carried out to investigate the dissipation rates of pesticides as well as to measure the terminal residues in chili peppers. Deltamethrin, dimethomorph, imidacloprid, mepanipyrim, and metalaxyl were applied to chili peppers 15 days prior to harvest. Chili pepper samples were collected at specified intervals and were subjected to residue analysis and dislodgeable residue study. In most cases, initial residue levels were rapidly dissipated with time. The dissipation pattern of pesticide residues fits well to first-order kinetics. Biological half-lives, as calculated from regression curves, of most pesticides were estimated to be
