Leaching of the S-metolachlor herbicide associated with paraquat or glyphosate in a no-tillage system [PDF]

open access: yesPesquisa Agropecuária Tropical, 2016
ABSTRACT The combined use of desiccant and residual herbicides is a common management practice under no-tillage systems. However, the effect of desiccant herbicides and mulch on the leaching of residual herbicide is unknown. This study aimed at assessing the leaching of the S-metolachlor herbicide applied to ryegrass sequentially or in association with

Integrated weed management in chickpea (Cicer arietinum L.)

open access: yesCogent Food & Agriculture, 2019
The poor competition ability of chickpea opens the door for weed to cause a serious yield loss. The experimental field is conducted to evaluate the integrated effects of pre-emergence herbicides and hand-weeding on weed control, yield components, yield ...

Decreased Glutathione Levels Enhance the Susceptibility of Maize Seedlings to Metolachlor [PDF]

open access: yes, 1993
The effect of decreased glutathione levels on the action of the herbicide metolachlor was studied in shoots of maize seedlings. Metolachlor inhibited growth by impairing the length, the dry weight, and the fresh weight of maize shoots.

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

open access: yesEcotoxicology 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

The application of mesotrione in combination with terbuthylazine, nicosulfuron and S-metolachlor in maize [PDF]

open access: yesZastita bilja, 2014
The paper examines the efficacy and selectivity of mesotrione in combination with terbuthylazine, nicosulfuron and S-metolachlor in maize crops. The studies were conducted during 2014, in two localities, and the following herbicides were applied: Mezotrion 100 g/L OD (mesotrione) in quantities of 1.0 and 1.2 L/ha; Egnit OD (mesotrione + nicosulfuron ...

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

open access: yesEcotoxicology, 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.

Transpiration Responses of Herbicide-Resistant and -Susceptible Palmer Amaranth (Amaranthus palmeri (S.) Wats.) to Progressively Drying Soil

open access: yesAgriculture, 2022
Drought events are predicted to increase in the future. Evaluating the response of herbicide-resistant and -susceptible weed ecotypes to progressive drought can provide insights into whether resistance traits affect the fitness of resistant weed ...

Novel tetronamides derived from mucobromic acid: synthesis, structural elucidation, DFT calculations and phytotoxic activity

open access: yesPest Management Science, EarlyView.
The acyclic mucobromic acid, activated by (1S)‐(+)‐10‐camphorsulfonic acid, afforded the chiral compound 1b, precursor for aza‐Michael addition/elimination on the butenolide yielding tetronamides 2b‐7b. Their relative SRSR configuration was confirmed by the spectrometric methods, DFT calculation and statistical methods.
