Zhou Y, Liu W, Wang T: [Effects of pesticides metolachlor and S-metolachlor on soil microorganisms in aquisols of Southern China. Ying Yong Sheng Tai Xue Bao. 2005 May;16(5):895-8.
I. Catalase activity]. This paper studied the effects of different concentrations (0, 5, 20, and 100 mg.kg (-1)) metolachlor and its enantiomer S-metolachlor (Dual Gold) on soil catalase activity. The results showed that 20 mg.kg (-1) metolachlor had the most successive stimulating effect, 5 mg.kg (-1) metolachlor had an inhibitory effect in the early period, while 100 mg.kg (-1) metolachlor had a stimulating effect in the late period. Different concentrations Dual Gold displayed a tendency stimulation-inhibition-stimulation. 5 and 100 mg.kg (-1) metolachlor might have more damage on soil ecosystem than different concentrations Dual Gold. |
