: Soil enzymes play a key role in energy transfer through the breakdown of soil organic matter and nutrient cycling, and therefore play an important role in agriculture. Therefore, this study was conducted to determine the effect of different concentrations of four selected pesticides (2 insecticides and 2 fungicides) on groundnut soil in black and red groundnut cultivated fields in Anantapuramu district, Andhra Pradesh, India. In a laboratory experiment, the effect of selected pesticides - dimethoate and thiodicarb, fungicides - fosety-Al and copper oxychloride on urease activity with different concentrations of 1.0-10 kg ha-1 was determined. Enzyme activity was determined in two parallel air-dried soil samples and incubated for 10, 20, 30 and 40days for soil enzyme i.e., urease was tested. Urease activity was significantly higher in insecticides compared to fungicides levels at 10 and 20 days of 5.0 kg ha-1 in black and red soil. In general, pesticides reduced the activity of soil enzymes, which decreased with increasing pesticide applications. Urease activity decreased dramatically as the incubation time increased to 30 and 40 days. The results of this study clearly show that field application rates do not affect enzyme activity during a longer incubation period (40 days). However, a higher concentration of fungicide (10 kg ha-1) causes inhibition of enzymatic activity.
