Abstract: The current study was conducted to study the physiological effect of pesticides on Faba bean plant (Vicia faba L.) growth using Chlorofete, (organophosphate insecticide ). The plants were irrigated with contaminated water at different concentrations (0.1, 1, 5, 10 and 25 ppm) with the control sample and studied its effects on germination and vegetative parameters of the plant, length and diameter of stem, leaf area, the time of flowering and number of number of flowering, results showed that the pesticide has a large and clear impact on these parameters as it reduced the percentage of germination, length and diameter of stem and decrease the leave area as well as speed up the flowering process and decrease number of flowers, leading to the end of the plant life cycle, 25 ppm concentration was is more effective than the other concentrations and the lowest effect at the concentration of 0.1 ppm which relatively led to the natural growth to the control sample, which confirms that phosphorus pesticides have a significant impact on plant productivity and reduced harvested.
