| Abstract | ||||
| The residual levels of abamectin, spinosad, and acetamipride were determined by HPLC-DAD moreover, penconazole, diniconazole and fipronil determined by using GC-ECD in tomato fruit under field conditions using QuEChERS methodology (Quick, Easy, Cheap, Effective, Rugged and Safe). The dissipation half-life time of abamectin, spinosad, acetamipride, diniconazole, penconazole and fipronil residues in tomato fruits were 3.91, 0.36, 1.19, 0.71, 4.19 and 1.78 days, respectively. Depending on the maximum residue limits (MRL), the pre-harvest interval (PHI) of abamectin, spinosad, acetamipride, diniconazole, penconazole, and fipronil were 10, 1, 1, 10,5 and 21daysafter the application, respectively. This recommended that the use of tomato fruits treated with these pesticides were safe for consumption after these intervals. | ||||
