The current study was conducted in the greenhouses and laboratories of the Department of Biology/College of Education for Pure Science/University of Mosul during the academic year 2023-2024 to demonstrate the effect of the pesticide glyphosate (a herbicide) at four concentrations on the concentration of three types of amino acids and the concentration of the pesticide in the vegetative parts of pea and oat plants, in addition to the control treatment.
The results showed that treatment with the pesticide glyphosate, at the fourth concentration (2.10) ml/5 liters, led to a decrease in the concentration of the three amino acids: aspartic acid, glutamic acid, and serine, as they reached (17.39), (219.61), and (245.83) ppm , respectively, compared to the control treatment for each amino acid. As for the concentration of the pesticide in the vegetative parts of the two plants, it was found that there was an increase in the concentration of the pesticide in the two plants whenever the concentration of the pesticide used in the research increased compared to the control treatment, as the concentration of the pesticide glyphosate in the vegetative parts of the pea reached (64.71) ppm, while the concentration of the pesticide in the oat reached (59.77) ppm when treating the plant with the pesticide at a concentration of (2.10) ml/5 liters compared to the control treatment, which amounted to (5.91) and (1.91) ppm in the vegetative parts of pea and oat plants, respectively.
