Fig. 3. Antioxidant enzymes; APX (A), GPX (B), POD (C) SOD (D) and CAT (E) extracted from roots of Solanum lycoperscium plants exposed to varying doses (0, 25, 50, 75, 100, 150 and 200 μg mL⁻¹) each of diazinon, imidacloprid and mancozeb. In this figure, bar diagrams represents the mean values of five replicates (n = 5). Corresponding error bars represents standard deviation (SD) of five replicates (SD, n = 5).
