ACCase cross-resistance in Italian ryegrass (Lolium multiflorum) sub-populations from Oregon, US

open access: yesJulius-Kühn-Archiv, 2012
ACCase-resistant Italian ryegrass (Lolium multiflorum) is one of the most troublesome weeds in US wheat production systems. This study had the objective of determining the resistance pattern of three subpopulations selected from a winter wheat field with

Comparative analysis of miRNAs of two rapeseed genotypes in response to acetohydroxyacid synthase-inhibiting herbicides by high-throughput sequencing. [PDF]

open access: yesPLoS ONE, 2017
Acetohydroxyacid synthase (AHAS), also called acetolactate synthase, is a key enzyme involved in the first step of the biosynthesis of the branched-chain amino acids valine, isoleucine and leucine.

A unified model for wild resistance dynamics and weed control using herbicide [PDF]

open access: yesarXiv, 2015
A major issue in the modelling of weed resistance to herbicide lies in effectively handling the wild dynamics, that is, the allele frequency prior to the herbicide application, and in particular when starting to use the herbicide. The wild allele frequency is a key variable as the resistance evolution is highly sensitive to it, moreover it is extremely

Highly sensitive silver decorated-graphene oxide-silicon nanowires hybrid SERS sensors for trace level detection of environmental pollutants [PDF]

open access: yesarXiv, 2021
In this study, we evaluated the sensing performance of silver nanoprism/graphene oxide/silicon nanowires (AgNPr/GO/SiNWs) nanohybrid system for effective detection of organic dye and herbicide residues in freshwater via surface-enhanced Raman scattering (SERS).

Sorption-Desorption Behavior of Imazethapyr and Imazapic on Six Brazilian Soils [PDF]

open access: yesPlanta Daninha, 2018
: The characterization of sorption-desorption for imazethapyr and imazapic in six agricultural soils was performed to assess the availability of these herbicides in pollution processes.

Supervised learning for crop/weed classification based on color and texture features [PDF]

open access: yesarXiv, 2021
Computer vision techniques have attracted a great interest in precision agriculture, recently. The common goal of all computer vision-based precision agriculture tasks is to detect the objects of interest (e.g., crop, weed) and discriminating them from the background. The Weeds are unwanted plants growing among crops competing for nutrients, water, and

Weed Resistance to Herbicides [PDF]

open access: yes, 2017
Weed resistance is more and more becoming a problem under intense agricultural conditions. Recognizing this problem has high practical importance not only for detection of resistant weeds but also for application of measures for prevention of development of resistance or control of already resistant weed populations.

4Weed Dataset: Annotated Imagery Weeds Dataset [PDF]

open access: yesarXiv, 2022
Weeds are a major threat to crops and are responsible for reducing crop yield worldwide. To mitigate their negative effect, it is advantageous to accurately identify them early in the season to prevent their spread throughout the field. Traditionally, farmers rely on manually scouting fields and applying herbicides for different weeds.

Herbicide Phytotoxicity and Resistance to Herbicides in Legume Plants [PDF]

open access: yes, 2012
Active substances in herbicides, just like in other pesticides, are chemical compounds synthesized in order to kill organisms which are harmful for cultivated plants. Therefore, they are toxins introduced on purpose by man into the environment. From the perspective of environmental protection, it is very significant that herbicides are most often ...

Herbicide Resistance in Plants [PDF]

open access: yesPlants, 2020
Herbicide resistance in weeds is perhaps the most prominent research area within the discipline of weed science today. Incidence, management challenges, and the cost of multiple-resistant weed populations are continually increasing worldwide. Crop cultivars with multiple herbicide-resistance traits are being rapidly adopted by growers and land managers
