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.

Environmental fate of S-Metolachlor: a review [PDF]

Planta Daninha, 2014
S-metolachlor is a preemergent herbicide used for the control of annual grasses and small-seeded broadleaf weeds in more than 70 agricultural crops worldwide. Recently, Smetolachlor has been used to control imidazolinone-resistant red rice in rice-soybean rotation in lowland environments of the Southern Brazil.

Herbicide toxicity to Nitrospirillum amazonense: assessing bacterial survival and microbial functionality. [PDF]

Pest Manag Sci
Herbicides elicit a spectrum of responses in Nitrospirillum amazonense, ranging from the stimulation of metabolic functions (biological nitrogen fixation, IAA production) to significant growth inhibition and acute toxicity. Abstract BACKGROUND Herbicides can exert significant toxicity on nontarget organisms, including plant growth‐promoting bacteria ...
