Effects of atrazine and S-metolachlor on stream periphyton taxonomic and fatty acid composition [PDF]

Ecotoxicology, 2023
Abstract Extensive pesticide use for agriculture diffusely pollutes aquatic ecosystems through leaching and runoff events and has the potential to negatively affect non-target organisms. Atrazine and S-metolachlor are two widely used herbicides often detected in high concentrations in rivers that drain nearby agricultural lands.

S-metolachlor persistence in soil as influenced by within-season and inter-annual herbicide use

Environmental Advances, 2022
The ability to predict fate of pesticides in the environment is crucial for sustainable management. This process starts with a proper characterization of the dissipation of a parent compound under different sets of conditions.

A Hydroponics Assay Distinguishes between S-metolachlor-tolerant and -sensitive Sweetpotato Cultivars

HortScience, 2020
Weed management is an important component of sweetpotato production. Currently, S-metolachlor is the only herbicide registered in sweetpotato that has some suppressive effect on nutsedge species (Cyperus spp.).

Enantioselective induction of a glutathione-S-transferase, a glutathione transporter and an ABC transporter in maize by Metolachlor and its (S)-isomer. [PDF]

PLoS ONE, 2012
The metabolism of chiral herbicides in plants remains poorly understood. Glutathione conjugation reactions are one of the principal mechanisms that plants utilize to detoxify xenobiotics. The induction by rac- and S-metolachlor of the expression of three

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 ...

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 ...

Effects of weed management and plant arrangements on yield index of sweet sorghum

Bioscience Journal, 2019
Sweet sorghum is currently an important alternative for ethanol production in sugar cane off-season. In this study was to evaluate the effects of plant arrangements and the application of atrazine and S-metolachlor on growth and productivity of sweet ...

Sensitivity of freshwater periphytic diatoms to agricultural herbicides [PDF]

, 2009
The biomonitoring of pesticide pollution in streams and rivers using algae such as diatoms remains difficult. The responses of diatomcommunities to toxic stress in streamwater are disturbed by the variations of environmental parameters.

Weed Management Programs in Grain Sorghum (Sorghum bicolor)

Agriculture, 2019
A field study was conducted in Arkansas over three years to evaluate various herbicide treatments, including sequential and tank-mix applications for weed control in grain sorghum (Sorghum bicolor). The herbicide treatments used were quinclorac, atrazine
