Current Status of Herbicide Resistance in the Iberian Peninsula: Future Trends and Challenges

open access: yesAgronomy, 2022
The evolution of herbicide resistance in weeds has emerged as one of the most serious threats to sustainable food production systems, which necessitates the evaluation of herbicides to determine their efficacy.

Molecular Mechanisms of Herbicide Resistance [PDF]

open access: yesWeed Science, 2015
Resistance to herbicides occurs in weeds as the result of evolutionary adaptation (Jasieniuk et al. 1996). Basically, two types of mechanisms are involved in resistance (Beckie and Tardif 2012; Délye 2013). Target-site resistance (TSR) is caused by changes in the tridimensional structure of the herbicide target protein that decrease herbicide binding ...

A bibliometric analysis of herbicide resistance in Africa

open access: yesScientific African, 2023
Herbicides were introduced in the 1950s, and since then, there has been an increase in herbicide-resistant weeds. This is apparent from the multiple (503) literature reviews on herbicide resistance worldwide.

Herbicide Resistance: Toward an Understanding of Resistance Development and the Impact of Herbicide-Resistant Crops [PDF]

open access: yesWeed Science, 2012
Development of herbicide-resistant crops has resulted in significant changes to agronomic practices, one of which is the adoption of effective, simple, low-risk, crop-production systems with less dependency on tillage and lower energy requirements. Overall, the changes have had a positive environmental effect by reducing soil erosion, the fuel use for ...

Quinclorac Resistance in Echinochloa crus-galli from China

open access: yesRice Science, 2019
Echinochloa crus-galli is a major weed in rice fields in China, and quinclorac has been long used for its control. Over-reliance of quinclorac has resulted in quinclorac resistance in E. crus-galli. Two resistant (R) E. crus-galli populations from Hunan,

TOTAL PROTEIN ANALYSIS AND TRANSMISSION ELECTRON MICROSCOPY AS METHODS FOR DETECTION OF CLODINAFOP-PROPARGYL HERBICIDE RESISTANCE IN THE GREEN ALGA Scenedesmus quadricauda [PDF]

open access: yesJournal of Plant Protection and Pathology, 2012
Green alga cultures of Scenedesmus quadricauda were treated with different concentrations of clodinafop-propargyl herbicide (0, 10.5 21, 42 and 84 ppm). Transmission electron microscopy and total protein analysis were applied to clarify the resistance of

Evolved polygenic herbicide resistance in Lolium rigidum by low‐dose herbicide selection within standing genetic variation

open access: yesEvolutionary Applications, 2013
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 ...

Herbicide Resistance in Setaria

open access: yes, 2016
The four documented cases of field selection for herbicide resistance in weedy Setaria are described in this chapter. In each case, weed control failure was observed in practice in the field. In all cases, resistance was target-site-based resistance and was due to single nucleotide mutations causing amino-acid substitutions at codon 264 of psbA ...

Herbicide-Resistant Crops: Utilities and Limitations for Herbicide-Resistant Weed Management

open access: yesJournal of Agricultural and Food Chemistry, 2010
Since 1996, genetically modified herbicide-resistant (HR) crops, particularly glyphosate-resistant (GR) crops, have transformed the tactics that corn, soybean, and cotton growers use to manage weeds. The use of GR crops continues to grow, but weeds are adapting to the common practice of using only glyphosate to control weeds.

Adaptive and maladaptive expression plasticity underlying herbicide resistance in an agricultural weed

open access: yesEvolution Letters, 2021
Plastic phenotypic responses to environmental change are common, yet we lack a clear understanding of the fitness consequences of these plastic responses.
