Abstract

In this paper, we studied the influence of different concentrations of chlorothalonil which was commonly used in North China, on the activities of soil invertase, catalase and urease. The results showed that the influence trend of chlorothalonil at different doses on soil enzyme activity was almost the same. For soil catalase, it showed significant activation. For soil urease, it showed stimulation firstly and inhibition later. For soil invertase, it showed strong inhibition. The influence degree was described as follows: catalase>; invertase>; urease. Furthermore, we established predictive model for the influence of chlorothalonil on soil enzyme activity with increasing cultivation time. This will provide scientific bases for rational application of pesticides.
