Probleme bei der Unkrautbekämpfung in einem Gebiet mit hohen Abundanzen von Ambrosia artemisiifolia und Möglichkeiten der Reduzierung der Beifuß- Ambrosie in dieser Region

open access: yesJulius-Kühn-Archiv, 2014
A distribution area of common ragweed (Ambrosia artemisiifolia) is situated in the south of Brandenburg. The weed species appears in arable fields and at roadsides. In some fields herbicide application is required due to the high frequency of weed plants.

Inorganic and Organic Clays as Carriers for Controlled Release of the Herbicide Hexazinone

open access: yesJournal of Agricultural and Food Chemistry, 2002
The risk of ground water contamination resulting from rapid leaching of highly soluble pesticides can be minimized through the application of the pesticide adsorbed on a matrix or carrier, which limits the amount of pesticide immediately available for undesirable losses.

Polyethyleneimine‐Modified Biosorbent Based on Banana Pseudostem Biomass for Environmental Remediation and Food Analysis

open access: yesAdvanced Sustainable Systems, EarlyView.
Biosorbents derived from banana pseudostem are functionalized with polyethyleneimine, with or without glutaraldehyde, and evaluated for dye removal and solid‐phase extraction. The materials exhibit high adsorption capacities and broad pH applicability in dye removal, while computational studies reveal amino groups as key interaction sites.

An aerated axenic hydroponic system for the application of root treatments: exogenous pyruvate as a practical case

open access: yesPlant Methods, 2018
Background Hydroponic systems are a convenient platform for plant cultivation when treatments are applied to the roots because they provide precise control of the composition of the growth medium, ensuring the availability of different compounds.

Weeds and crop yields under conservation tillage in organic farming. [PDF]

open access: yes, 2010
Conservation tillage in conventional agriculture tends to make the cropping systems more dependent on herbicides. Organic farming principles could solve this problem. However, direct drilling under a cover crop in organic farming remains difficult.

Adsorption of the Herbicide Simazine by Montmorillonite Modified with Natural Organic Cations

open access: yesEnvironmental Science & Technology, 2003
Three organic cations with a natural origin (L-carnitine, L-cystine dimethyl ester, and thiamine) were introduced at different loadings in the interlayer of a low-charge montmorillonite, and the performance of the modified clays as adsorbents of the herbicide simazine was investigated using batch adsorption-desorption experiments.

A Reaction‐Diffusion Frame for Accessing Metabolic O2 Fluxes in Single Microalgal Cells with Low‐Cost Wide‐Field Imaging of Nanosensor Luminescence Lifetime

open access: yesAdvanced Science, EarlyView.
Individual Chlamydomonas reinhardtii (C. reinhardtii) living cells on an agarose pad containing luminescent O2 nanosensors are imaged with a simple wide‐field protocol of lifetime imaging. The resulting maps of phosphorescence lifetime are analyzed within a reaction‐diffusion frame to access the distribution of metabolic O2 fluxes generated by single ...

Fate of the organophosphate herbicide glyphosate in arable soils and its relationship to soil phosphorus status [PDF]

open access: yes, 2009
Glyphosate is one of the world's most widely used herbicides. This study was undertaken to unravel the factors affecting its movement, sorption, persistence and leachability in different Finnish soils to create a sound basis for risk assessment. Field
