Abstract:

Many studies have shown that pesticides use have some effect on soil biology. However little information is available concerning the effect of pesticides on soil enzyme activities in semi arid zone of Africa. The aim of this study was to investigate the effect of three pesticides usually used (endosulfan, deltamethrin and profenofos), on soil Fluorescein Diacetate (FDA) and dehydrogenase activities from cultivated and fallow plot. Enzyme activities were followed in 5 days incubated soil, containing 200 mg/kg of each pesticide. The results showed that endosulfan, deltamethrin and profenofos significantly decreased soil dehydrogenase activity (p<0.005). In incubated soils no effect of these pesticides on Fluorescein Diacetate (FDA) activity was found (p>0.005). These results clearly show the impacts of these pesticides on soils enzyme activites.
