Dissipation and Residue of S-metolachlor in Maize and Soil
Bulletin of Environmental Contamination and Toxicology, 2008The purpose of this article was to establish a simple residue analysis method for S-metolachlor in maize and to study its dissipation and residue in maize field eco-system. The results showed that S-metolachlor declined rapidly in maize seedling and soil after application. The half-lives of S-metolachlor in maize seedlings in Beijing and Changchun were

Effect of s-metolachlor application timing on cabbage tolerance
Crop Protection, 2007There is limited information on the effect of s-metolachlor application timing on cabbage tolerance in Ontario. A total of five field trials (1999–2004) were established near Ridgetown Ontario, Canada to evaluate tolerance of cabbage to s-metolachlor applied pretransplant incorporated, pre-transplant and post-transplant at 800, 1600 and 2400 g a.i./ha.

Effects of s-metolachlor on early life stages of marbled crayfish
Pesticide Biochemistry and Physiology, 2019The effects of s-metolachlor chronic exposure at concentrations of 1.1 μg/L (maximal real environmental concentration in the Czech Republic), 11 μg/L (environmental relevant concentration) and 110 μg/L on early life stages of marbled crayfish (Procambarus virginalis) was evaluated under laboratory conditions.

Comparative toxicity of racemic metolachlor and S-metolachlor to Chlorella pyrenoidosa
Aquatic Toxicology, 2009The toxicity of the chiral herbicides rac-metolachlor and S-metolachlor to Chlorella pyrenoidosa was determined and compared in this study, based on four different test endpoints: the growth inhibition rate, the chlorophyll a and chlorophyll b concentration, the catalase activity, and the ultrastructural morphology of cells.

Carrier effect of S-metolachlor by microplastics and environmental risk assessment
Journal of Water Process Engineering, 2021Abstract Organic pesticide pollutants have obvious negative effects on organisms in the environment. As an emerging organic contaminant, the ubiquitous microplastics (MPs) are undoubtedly regarded as the focus of global attention. MPs originate from the fragmentation of large plastic waste or direct environmental emissions. This research explored the

Adsorption of the herbicide S-Metolachlor on periodic mesoporous organosilicas
Chemical Engineering Journal, 2013Abstract Due to their hydrophobic pore systems and high surface areas, periodic mesoporous organosilicas (PMOs) offer unique properties for use as adsorbents of organic compounds. Two organosilicas (ethane-PMO and benzene-PMO) and a silica (PMS) were synthesized following a similar procedure.

Metolachlor, S-metolachlor and their role within sustainable weed-management
Crop Protection, 1998Abstract The herbicide metolachlor has been widely used for over 20 years for selective weed control in more than 70 crops worldwide. Its favourable soil behaviour and low risk for developing weed resistance means that metolachlor integrates well into sustainable weed-management practices, such as conservation tillage.
