Currently, the tomato fruit worm or cotton bollworm <em>Helicoverpa armigera</em>, with a wide host range, is one of the key pests of tomatoes, which has reduced the marketability of this product, and chemical control of this pest is one of the common methods of managing this pest. In this study, the evaluation of the pre-harvest interval (PHI) was carried out at the optimal doses of each of the studied pesticides. Alverd^@ 240 SC insecticide at a dose of 1000 ml/ha and Proclaim Fit^@ UV 500 WG insecticide at a dose of 100 g/ha showed the best efficiency. Therefore, the residue of these pesticides in tomato crops and the evaluation of the proposed Karnes period were carried out at these doses. Based on the results of the insecticide residues of metaflumizone, lufenuron, and emamectin benzoate in tomatoes treated with these pesticides, the 3-day pre-harvest interval of Alvord (metaflumizone) and the 7-day pre-harvest interval of Proclimfit (lufenuron and emamectin benzoate) were investigated and verified. The residue results, compared to the national MRL of these pesticides, showed that the 3-day PHI of metaflumizone and the 7-day PHI of lufenuron and emamectin benzoate in tomatoes were acceptable.<br />.
