Abstract:
Supervised field trials were carried out to investigate the effects of household processing to eliminate the imidacloprid, lambda cyhalothrin and spiromesifen residues in cabbage heads. Individual spray applications of imidacloprid, lambda cyhalothrin and spiromesifen were made at recommended dose. After spray, cabbage heads were collected at 1, 3 and 5 day interval and were subjected to various decontamination processes like tap water washing, saline water washing (2% NaCl), lukewarm water washing, open pan cooking, microwave cooking and outer leaf removal. Further, after processing the head samples were examined using QuEChERS technique and residues were estimated by GC-MS, ECD and HPLC. Among various decontamination processes, microwave cooking was found most effective which provided 92.95-100 percent relief from insecticide residues in cabbage heads followed by outer leaf removal (80.31-100%), open pan cooking (74.01-100%), saline water washing (42.45-100%), lukewarm water washing (29.24-100%) and tap water washing (23.27-100%).
