Dissipation of S-metolachlor in plant and soil and effect on enzymatic activities. [PDF]

Environ Monit Assess, 2017
The present study aimed at evaluating the dissipation of S-metolachlor (S-MET) at three doses in maize growing on diverse physico-chemical properties of soil. The effect of herbicide on dehydrogenase (DHA) and acid phosphatase (ACP) activity was estimated. A modified QuEChERS method using LC-MS/MS has been developed.
