Target‐site and non‐target‐site mechanisms confer multiple herbicide resistance in waterhemp (Amaranthus tuberculatus) accessions from Wisconsin

Pest Management Science, EarlyView.
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 ...

Weed Control in Corn (Zea mays L.) as Influenced by Preemergence Herbicides

International Journal of Agronomy, 2016
Field studies were conducted in central and south-central Texas from 2013 through 2015 to evaluate crop tolerance and efficacy of various preemergence herbicides alone and in combination for weed control in field corn. Acetochlor and pendimethalin alone,

Mechanisms of tolerance and high degradation capacity of the herbicide mesotrione by Escherichia coli strain DH5-α. [PDF]

PLoS ONE, 2014
The intensive use of agrochemicals has played an important role in increasing agricultural production. One of the impacts of agrochemical use has been changes in population structure of soil microbiota.

Barnyardgrass shows sensitivity to reduced doses of topramezone at different growth stages [PDF]

, 2019
Using less than the labelled dose of herbicides depends mostly on weed spectrum and growth stage of target weeds. The aim of the greenhouse experiment was to determine the efficacy of recommended (67.2 g a.i. ha-1) and reduced doses (44.8, 33.6, 22.4, 16.

Integrated genomic and transcriptomic approaches reveal oxidative stress adaptation mechanisms in a mesotrione‐resistant Amaranthus tuberculatus biotype

Pest Management Science, EarlyView.
Integrated GWAS and transcriptomics in a Canadian waterhemp biotype reveal mesotrione resistance is polygenic and metabolically driven. Significant SNPs and 187 herbicide‐responsive genes point to enhanced redox homeostasis, glutathione‐linked detoxification, lipid/secondary metabolism, and oxidative stress responses. Resistance arises from coordinated,

Eficácia de herbicidas aplicados em diferentes épocas sobre B. pilosa e I. quamoclit em área de cana-de-açúcar colhida mecanicamente Effectiveness of herbicides applied at different times on B. pilosa and I. quamoclit in mechanically harvested sugarcane area

Planta Daninha, 2009
O objetivo deste trabalho foi estudar a eficácia agronômica de herbicidas utilizados em áreas no sistema da colheita da cana crua, visando o controle de Ipomoea quamoclit e Bidens pilosa em lavoura comercial de cana-soca, com solo de textura argilosa, no

Effect of plant height on control of multiple herbicide-resistant Palmer amaranth (Amaranthus palmeri) in glufosinate/glyphosate-resistant corn

Frontiers in Agronomy, 2023
Multiple herbicide-resistant (MHR) Palmer amaranth is a troublesome weed in several crops across the USA, including corn. Due to unavoidable weather conditions, it is sometimes not possible for growers to apply pre-emergence herbicide; therefore, post ...

Differential sensitivity of locally naturalized Panicum species to HPPD- and ALS-inhibiting herbicides [PDF]

, 2014
Panicum schinzii (Transvaal millet), P. dichotomiflorum (Fall panicum) and P. capillare (Witchgrass) are alien panicoid grasses that have gradually spread and are now locally naturalized in corn fields in Belgium.

Thirty years of glyphosate‐resistant crops and weeds: Current situation and future prospects

Pest Management Science, EarlyView.
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.

Mesotrione carryover to soybeans [PDF]

, 2004
Mesotrione provides excellent residual control and breaks down readily in the soil provided there is sufficient moisture. Another important consideration is the rate of application, the timing of application, and soil characteristics likely influences ...
