In this study we sought to determine the effects of spraying nano-iron oxide and vitamin C on certain physiological traits, yield components, and volatile oil content of black seed plant (Nigella sativa) during the 2023 season, November 5. Concentrations of nano-iron oxide (0, 40, 80, 120 mg L⁻¹) and vitamin C (0, 50, 100 mg L⁻¹) were applied as foliar sprays to plants cultivated in plastic pots using a completely randomized design (CRD) in experiment. Results indicate that the treatment of 120 mg L⁻¹ nano-iron oxide together with 100 mg L⁻¹ vitamin C produced a highly significant improvement on most of the selected traits. The treatment proved better in yield components of plant such as number of capsules per plant (34.50), number of seeds per capsule (48.17), 1000 seed weight (3.99 g) and volatile oil percent (2.09%).

Contemporary control tactics emphasize the biological management of immature mosquito stages. It was observed that a seedling weighing 10 g in 100 cm of water containing Origanum vulgare and 30 larvae of Culex pipiens molestus accelerated their life cycle duration from 14 days in the control group to 11 days in the experimental group, alongside an 80% apparent reduction in larvae of C. pipiens molestus. The efficacy diminished to 50% and 30% at 200 cm and 300 cm, respectively, with stable plant weight. At start, there was a distinct distortion of the complement; Mint of the species Mentha pulegium has a lethal impact of 50% on mosquito larvae with individual seedlings. The constant weight in 100 cm of water was reduced to 35%, while an increase of 20% in water amount was seen at 200 cm and 300 cm, respectively, with stable plant weight. Additionally, this resulted in deformities in the remaining buds (inability to fly) by 18% ± 5%. The mint plant had no impact on the life cycle of mosquitoes.
