Bewertung von Metazachlor-haltigen Herbiziden zur Bekämpfung von Acker-Fuchsschwanz in Winterraps

Julius-Kühn-Archiv, 2020
Die Auswertung von Kleinparzellen-Versuchen der letzten 20 Jahre zeigt eine Abhängigkeit der Wirksamkeit Metazachlor-haltiger Herbizide gegen Acker-Fuchsschwanz von Anwendungstermin und Aufwandmenge. Die höchsten Wirkungsgrade mit der geringsten Streuung

Field studies on the germination behaviour of black-grass (Alopecurus myosuroides Huds.) depending on sowing date und winter wheat variety in Northern Germany

Julius-Kühn-Archiv, 2014
Black-grass (Alopecurus myosuroides, Huds.) is the most important herbicide-resistant weed in Europe. In Germany it is not only a problem in the maritime influenced areas like Schleswig-Holstein and Lower Saxony anymore, as well in other regions black ...

Sequence characterization of eccDNA content in multiple blackgrass (Alopecurus myosuroides) populations

, 2023
Alopecurus myosuroides (blackgrass) is a problematic weed of Western European winter wheat and its success is largely due to widespread multiple-herbicide resistance. Previous analysis of F2 seed families derived from two distinct blackgrass populations exhibiting equivalent non-target site resistance (NTSR) phenotypes shows resistance is polygenic and

Validation of the chlorophyll fluorescence imaging method (CFI) for early detection of herbicide resistance in weeds

Julius-Kühn-Archiv, 2014
The increasing number of herbicide tolerant weed populations is illustrating the increasing demand for reliable methods for an accelerated detection of herbicide tolerance compared to greenhouse studies.

In planta analysis of the mode of action of cinmethylin and confirmation of fatty acyl‐ACP thioesterases (FATs) as primary site of action

Pest Management Science, EarlyView.
In planta analysis of the mode of action of cinmethylin and confirmation of fatty acyl‐ACP thioesterases (FATs) as primary site of action. Cinmethylin inhibits FATs, disrupting eukaryotic de novo lipid biosynthesis and causing defects in cell division, elongation and integrity. We confirm FATs as the primary site of action in planta.

Linkage of the current ALS-resistance status with field history information of multiple fields infested with blackgrass (Alopecurus myosuroides Huds.) in southern Germany

Julius-Kühn-Archiv, 2016
The repetitive use of herbicides as major tool to control troublesome weeds in agriculture caused an increase in resistant weeds lately, especially when Integrated Weed Management principles were ignored.

Spatial and temporal development of ACCase and ALS resistant Black-grass (Alopecurus myosuroides Huds.) populations in neighboring fields in Germany

Julius-Kühn-Archiv, 2014
The repetitive use of herbicides of a given mode of action as primary tools to control weeds in simplified cropping systems has led to the development of resistant populations.

Non-target Site Herbicide Resistance Is Conferred by Two Distinct Mechanisms in Black-Grass (Alopecurus myosuroides)

Frontiers in Plant Science, 2021
Non-target site resistance (NTSR) to herbicides in black-grass (Alopecurus myosuroides) results in enhanced tolerance to multiple chemistries and is widespread in Northern Europe.

Herbicide spring treatments for the control of brome grasses (Bromus spp.) in winter cereals

Julius-Kühn-Archiv, 2014
The efficacy of different ALS-inhibiting herbicides for the control of brome species (Bromus spp.) was tested in three field trials in the year 2010 – 2012 in the region of North-West-Bavaria Franken.

Graminicide resistance in a blackgrass (Alopecurus myosuroides) population correlates with insensitivity of acetyl‐CoA carboxylase [PDF]

Plant, Cell & Environment, 2003
ABSTRACTThe appearance of biotypes of the annual grass weed black‐grass (Alopecurus myosuroides L. Huds), which are resistant to certain graminicides, is the most significant example of acquired resistance to herbicides seen so far in European agriculture. An investigation was perfomed into the basis of the specific cross‐resistance to cyclohexanedione
