Aim of the study to test tolerance of Hydrilla verticillata plant to different concentrations of pesticides (glyophosate and lambda cyhalothrin) and to determine the extent of the physiological changes that occur in the plant. Collect the plant from Euphrates River and acclimation in laboratory during 15-day culture in glass aquarium three frequency exposing to different concentrations of glyophosate (2000, 6000, 12000, 24000 ppm) and lambda-cyhalothrin (33,66,166,332 ppm). Measuring total chlorophyll, chlorophylla, chlorophyll b, total protein, catalase enzyme and super oxide dismutase during (1, 3, 7 and 10 days). The current study showed a decrease in total chlorophyll and total protein content during the experiment period, while a gradual increase in the superoxide dismutase (SOD) values during the experimental period compared to the control. The values of the activity of catalase enzyme of pesticides observed a gradual decreased during experimental period. The stem of plant not affect to glyphosate while the leaf had clear affect during (3, 7 and 10 days), while affected steam and leaf of Hydrilla verticillata to lambda cyhalothrin pesticide. Our results indicate that glyphosate concentrations from 2000 to 24000 ppm can induce oxidative stress in Hydrilla verticillata and may impede metabolism processes for protein and pigments for plant. Our results suggest that the sensitivity of Hydrilla verticillata to higher concentrations of glyphosate and lambda cyhalothrin exposure.
