Mechanism of Resistance to S-metolachlor in Palmer amaranth [PDF]

Frontiers in Plant Science, 2021
Herbicides are major tools for effective weed management. The evolution of resistance to herbicides in weedy species, especially contributed by non-target-site-based resistance (NTSR) is a worrisome issue in crop production globally. Glyphosate-resistant

Enantioselective Oxidative Stress and DNA Damage Induced by Rac- and S-metolachlor on the Earthworm Eisenia fetida [PDF]

Toxics, 2023
Metolachlor is a widely used chiral herbicide. However, information on its enantioselective toxicity to earthworms, an important soil organism, remains limited.

Multiomics Analysis of the Mechanism by Which Gibberellin Alleviates S-Metolachlor Toxicity in Rice Seedlings [PDF]

Plants
S-metolachlor is a selective pre-emergence herbicide used in dryland. However, it is challenging to employ in paddy fields due to its phytotoxic effects on rice.

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.

Evaluation of confirmatory data following the Article 12 MRL review for S-metolachlor. [PDF]

EFSA J, 2023
The applicant Syngenta Crop Protection AG submitted a request to the competent national authority in Germany to evaluate the confirmatory data that were identified for S-metolachlor in the framework of the maximum residue level (MRL) review under Article 12 of Regulation (EC) No 396/2005 as not available. To address the data gaps, a new freezer storage

A comparative study of rac- and S-metolachlor toxicity to Daphnia magna

Ecotoxicology and Environmental Safety, 2006
Racemic product of metolachlor contains two R enantiomers and two S enantiomers. S-metolachlor is now widely used instead of rac-metolachlor because the former is more effective in herbicidal activity than the latter. The acute and chronic toxicities of rac- and S-metolachlor to Daphnia magna were determined and compared in this study.

Combined effects of S-metolachlor and benoxacor on embryo development in zebrafish (Danio rerio)

Ecotoxicology and Environmental Safety, 2022
It is necessary to study the combined toxicity of an herbicide and its safener because the two are often used in combination. S-metolachlor and its safener benoxacor have been detected in aquatic environments and can individually damage the oxidative ...

Performance of an S‐metolachlor capsule suspension for barnyardgrass control and crop tolerance in fenclorim‐treated rice

Agrosystems, Geosciences & Environment
Barnyardgrass [Echinochloa crus‐galli (L.) P. Beauv.] is the most problematic weed of delayed‐flooded rice (Oryza sativa L.) systems in the mid‐southern United States. Recent findings suggest that acetochlor can achieve effective barnyardgrass control in
