The purpose of the present study was to provide information about the effect exerted by fonofos pesticide on dehydrogenase activity of Mollic Gleysol, Eutric Fluvisol and Eutric Histosol soil samples. The effect of fonofos on dehydrogenase activity was evaluated taking into consideration the pesticide dose and soil incubation time. It was found that soil dehydrogenase activity showed an inhibitory effect with increase of the pesticide doses. Dose on the level of 1 mikrogram g-1 of pesticide caused 5-21% inhibition of enzymatic activity, whilst ten times higher doses resulted in 17-44% drop of activity in comparison to the control. Increase of dehydrogenase activity was also connected with fall of redox potential (Eh). The results suggest a negative effect of fonofos on soil dehydrogenase activity in the first stage after application. |
