Both fresh and processed tomato cultivars are preferable and considered as an economic crop. It grows throughout the year as an economic crop by vegetable growers, both in a small and commercial scale. Tomato plant ( Solanum lycopersicum L.) is among the most crucial edible and nutritious vegetable crops in Egypt. The results proved that the examined insecticides, Challenger, Radiant, Vapcomic, especially, Emperor and Coragen can be successfully used in the IPM tactic against T. Moreover, Challenger, Radiant, and Vapcomic revealed minor differences with Emperor and Coragen of the efficiency and marketable yield. These two insecticides proved again the maximum total and marketable yields. ![]() The most potent biochemical effects were ascribed to Emperor and Coragen insecticides. In addition, they significantly minimized the activity of the enzymatic and non-enzymatic antioxidants. Concerning the biochemical effects of the most potent insecticides on tomato plants, all treatments induced promising effect on the photosynthetic pigments. The levels of insect infestation reduced by 98.74 and 95.51% after 7 days of spraying for the most effective insecticides, Emperor and Coragen, respectively, while the other examined insecticides were at par with one another. ![]() Accordingly, these most potent insecticides were evaluated under field circumstances. The laboratory assessment of the examined insecticides demonstrated that Emperor (Emamectin benzoate) and Coragen (Chlorantraniliprole) were the most superior (LC 50 = 0.26 and 0.46 mg L −1, respectively), followed by Radiant (Spinetoram), Vapcomic (Abamectin), and Challenger (Chlorfenapyr) (LC 50 = 0.59, 0.60, and 24.07 mg L −1, respectively). Moreover, all conventional insecticide failed these characteristics. ResultsĪll non-conventional insecticides passed the physico-chemical properties except Actra (thiamethoxam) which failed in pH test. The physico-chemical properties along with the insecticidal potency of seven non-traditional insecticides from different classes compared with three conventional insecticides were assessed versus Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) below laboratory and field conditions.
