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.

Evolved polygenic herbicide resistance in Lolium rigidum by low-dose herbicide selection within standing genetic variation [PDF]

, 2012
The interaction between environment and genetic traits under selection is the basis of evolution. In this study, we have investigated the genetic basis of herbicide resistance in a highly characterized initially herbicide-susceptible Lolium rigidum ...

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

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.

Target-site mutations Ile1781Leu and Ile2041Asn in the ACCase2 gene confer resistance to fluazifop-p-butyl and pinoxaden herbicides in a johnsongrass accession from Arkansas, USA. [PDF]

Plant Direct
Abstract Johnsongrass [Sorghum halepense (L.) Pers.] is a troublesome weed species in different agricultural and non‐agricultural areas. Because of its biology, reproductive system, and seed production, effective management is challenging. An accession with low susceptibility to the acetyl‐CoA carboxylase (ACCase)‐inhibiting herbicides fluazifop‐p ...

The identification of QTL controlling ergot sclerotia size in hexaploid wheat implicates a role for the Rht dwarfing alleles [PDF]

, 2015
The fungal pathogen Claviceps purpurea infects ovaries of a broad range of temperate grasses and cereals, including hexaploid wheat, causing a disease commonly known as ergot.

Molecular Basis of Blackgrass (Alopecurus Myosuroides HUDS.) Resistance to Sulfonylurea Herbicides

Journal of Plant Protection Research, 2011
Molecular Basis of Blackgrass (Alopecurus MyosuroidesHUDS.) Resistance to Sulfonylurea HerbicidesBlackgrass biotype resistant to the mesosulfuron + iodosulfuron mixture has been found in Poland and was investigated in this study. Seedlings that survived double-dosed herbicide treatment were submitted to molecular analysis in order to explain the ...

Evolutionary-thinking in agricultural weed management [PDF]

, 2009
Agricultural weeds evolve in response to crop cultivation. Nevertheless, the central importance of evolutionary ecology for understanding weed invasion, persistence and management in agroecosystems is not widely acknowledged.

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-inversion tillage in organic arable cropping [PDF]

, 2008
The opportunities for using an non-inversion tillage (NI) approach in organic systems has not been well investigated by research and what research has been done has not perhaps been sufficiently long-term.
