Landscapes of risk: A comparative analysis of landscape metrics for the ecotoxicological assessment of pesticide risk to bees

Journal of Applied Ecology, Volume 61, Issue 5, Page 975-986, May 2024.
Predicting pesticide risk based on landscape patterns could enable landscape‐scale ERA. However, simple metrics of landscape pattern, such as proportion of agricultural land, are not sufficient. We found that risk observed in bee‐collected pollen was best predicted when integrating spatialized pesticide use in the pesticide exposure model, underscoring

Vergleich zweier Zwischenfrucht-Anbauverfahren von Zuckerrüben im Praxisversuch, unter Berücksichtigung verschiedener Herbizidwirkstoffe

Julius-Kühn-Archiv, 2020
Zukünftig wird sich der Anbau von Zuckerrüben erschweren. Grund dafür ist unter anderem, dass in absehbarer Zeit immer mehr herbizide Wirkstoffe wegfallen, da sie ihre Zulassung verlieren.

A comparison of seven innovative robotic weeding systems and reference herbicide strategies in sugar beet (Beta vulgaris subsp. vulgaris L.) and rapeseed (Brassica napus L.)

Weed Research, Volume 64, Issue 1, Page 42-53, February 2024.
Abstract More than 40 weeding robots have become commercially available, with most restricted to use in crops or fallow applications. The machines differ in their sensor systems for navigation and weed/crop detection, weeding tools and degree of automation.

Rapid Screening of 300 Pesticide Residues in Commercially Available Vegetable‐, Fruit‐, and Cereal‐Based Baby Foods by Using Amino‐Functionalized Multiwalled Carbon Nanotubes with QuEChERS and Gas Chromatography‐Electrostatic Field Orbitrap High‐Resolution Mass Spectrometry

Journal of Food Quality, Volume 2024, Issue 1, 2024.
A new method for screening 300 pesticide residues in fruit‐, vegetable‐, and cereal‐based baby foods by an improved QuEChERS purification method based on amino‐functionalized multiwalled carbon nanotubes (NH2‐MWCNTs) combined with gas chromatography‐electrostatic field orbitrap high‐resolution mass spectrometry (Orbitrap GC‐MS) was developed.

Optimization of Metamitron Rate Applied PRE in Sugar Beet for Management of Palmer amaranth (Amaranthus palmeri S. Watson)

Weed Technology
The prevalence of glyphosate- and ALS-inhibitor-resistant Palmer amaranth has substantially impacted sugar beet yield across CO and NE since 2020. While metamitron applied PRE has been previously reported to effectively control glyphosate-resistant (GR ...

Tergitol as a possible thinning agent for peach cv. Redhaven

Horticultural Science, 2014
The effect of different blossom thinners ammonium thiosulfate (ATS) (1%, 2%), Armothin (1.5%), Tergitol-TMN-6 (0.5%, 1%), applied on peach cv. Redhaven at 50-60% full bloom was evaluated in thinning experiments in south-west Slovenia.
