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. | lld:pubmed |
