Abstract

Effects of metolachlor on the activities of cellulase, phosphatase, urease and protease in silty clay soil, were evaluated for up to 28 days. Metolachlor at 10 ppm and above caused a significant reduction in phosphatase and urease activities for the entire period of incubation. Cellulase activity decreased, especially in the presence of 20 or 50 ppm, during day 1 but recovered at day 21 of incubation when compared with the first day at all concentrations. At day 1, a marked reduction in protease activity to only 30% of the control was observed at 50 ppm. At the 28-day sampling, protease activity in metolachlor-treated soil doubled that of the first day of incubation.
