Non-triazine photosystem II inhibitors provide effective control of metabolic atrazine-resistant Amaranthus tuberculatus. [PDF]

Pest Manag Sci
Metabolism‐based atrazine‐resistant Amaranthus tuberculatus populations ACR and MCR exhibit little or no cross‐resistance to amicarbazone and metribuzin, suggesting that non‐halogenated Group 5 herbicides can be utilized to re‐establish effective control.

Thirty years of glyphosate-resistant crops and weeds: Current situation and future prospects. [PDF]

Pest Manag Sci
Since 1996, when the first glyphosate‐resistant crop was commercialized and the first resistant weed was reported, resistance has expanded globally. This review analyzes emergence patterns across weed species, crops, regions, resistance mechanisms, and herbicides.

Target-site and non-target-site mechanisms confer multiple herbicide resistance in waterhemp (Amaranthus tuberculatus) accessions from Wisconsin. [PDF]

Pest Manag Sci
The A101 accession is the first confirmed case of hydroxyphenyl pyruvate dioxygenase resistance in Amaranthus tuberculatus in Wisconsin, and the first report of P450s associated with atrazine resistance in A. tuberculatus globally. Abstract BACKGROUND A preliminary screening identified a multiple herbicide‐resistant waterhemp, Amaranthus tuberculatus ...

Multiple Resistance Mechanisms Involved in Glyphosate Resistance in Eleusine indica

Plants, 2022
Glyphosate is a non-selective herbicide and is widely used for weed control in non-cultivated land in China. One susceptible (S) and five putative glyphosate-resistant (R1, R2, R3, R4, and R5) Eleusine indica biotypes were selected to investigate their ...

Cytochrome P450 Herbicide Metabolism as the Main Mechanism of Cross-Resistance to ACCase- and ALS-Inhibitors in Lolium spp. Populations From Argentina: A Molecular Approach in Characterization and Detection

Frontiers in Plant Science, 2020
Knowledge about the mechanisms of herbicide resistance provide valuable insights into evolving weed populations in response to selection pressure and should be used as a basis for designing management strategies for herbicide-resistant weeds.

Repeated origins, widespread gene flow, and allelic interactions of target-site herbicide resistance mutations

eLife, 2022
Causal mutations and their frequency in agricultural fields are well-characterized for herbicide resistance. However, we still lack understanding of their evolutionary history: the extent of parallelism in the origins of target-site resistance (TSR), how

Target-Site and Non-target-Site Resistance Mechanisms Confer Multiple and Cross- Resistance to ALS and ACCase Inhibiting Herbicides in Lolium rigidum From Spain

Frontiers in Plant Science, 2021
Lolium rigidum is one the worst herbicide resistant (HR) weeds worldwide due to its proneness to evolve multiple and cross resistance to several sites of action (SoA).

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

Agronomy, 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.

The analysis of reference genes expression stability in susceptible and resistant Apera spica-venti populations under herbicide treatment

Scientific Reports, 2021
Weed resistance to herbicides constitutes a serious problem to world crop production. One of the weeds that are significantly threatening the crops’ yield and quality is Apera spica-venti. The target-site resistance (TSR) mechanism of A.

Transcriptome Profiling to Identify Genes Involved in Non-Target-Site-Based Resistance to Clodinafop-Propargyl in Asia Minor Bluegrass (Polypogon fugax)

Agronomy, 2022
Asia Minor bluegrass (Polypogon fugax Nees ex Steud.) is a problematic grass weed of winter crops in China, where some populations have become resistant to herbicides. Previously, we identified a P.
