Hexaconazole and Triazophos are pesticides are commonly used for control of fungal diseases and insect pest respectively in vegetable crops. The effect of these two pesticides on enzymatic activities in germinating seeds of spinach and gaur is studied in present investigation. α-Amylase activity is found to increase in 0.10% and 0.15% Hexaconazole treated seeds of spinach (Spinacea oleracea L.) and gaur (Cyamopsis tetragonolobus L. Taub) as compared to control, whereas lower concentrations of Triazophos inhibit its activity in spinach. The Triazophos stimulate enzyme activity at 0.05%, 0.20% and 0.30% in germinating seeds of gaur. The minimum activity of protease observed in all concentrations of Hexaconazole and Triazophos than control of both vegetable crops. The activity of acid phosphatase found to be increased in germinating seeds of spinach and gaur treated with increasing concentrations of Hexaconazole while it is decreased with increasing concentration of Triazophos
