Degradation of S-metolachlor in soil as affected by environmental factors [PDF]

Journal of soil science and plant nutrition, 2014
S-Metolachlor is a promising alternative to metolachlor; however, there are concerns about its environmental fate following soil application. The present study was conducted to investigate the effects of several environmental factors on the degradation rate of S-metolachlor in soil.

Evaluating percolation of the herbicide S-metolachlor with bioindicator plants

Revista de Ciências Agrarias - Amazon Journal of Agricultural and Environmental Sciences, 2015
Leaching can be infl uenced by the physical characteristics of soil and precipitation when the herbicide S-metolachlor is used intensively in sugarcane areas. The objective of this study was to use bioindicator plants to evaluate the percolation potential of S-metolachlor when submitted to natural pluviometric precipitation in two soils of contrasting ...

The agrochemical S-metolachlor disrupts molecular mediators and morphology of the swim bladder: Implications for locomotor activity in zebrafish (Danio rerio)

Ecotoxicology and Environmental Safety, 2021
Metolachlor herbicides are derived from the chloroacetamide chemical family of which there are the S- and R-metolachlor isomers. S-metolachlor is a selective herbicide that inhibits cell division and mitosis via enzyme interference. The herbicide is used
