Resistance of flaxleaf fleabane (Conyza bonariensis (L.) Cronquist) to glyphosate

Bulletin of the National Research Centre, 2020
Background Resistance to glyphosate has been reported in flaxleaf fleabane populations within a number of grain growing areas in southern Queensland and northern New South Wales and other cropping regions across Australia.

Environmental Pesticide Exposure in the Etiology of Pediatric Brain Tumors and Leukemia: A Scoping Review of Epidemiological Studies

International Journal of Cancer, EarlyView.
ABSTRACT Pediatric cancer is a significant cause of morbidity and mortality in children. The etiologies of pediatric cancer are largely unknown, but environmental pesticide exposures are likely to contribute. Chronic low‐dose exposure to pesticide mixtures through drinking water is a growing concern in agricultural communities.

EPSPS Gene Copy Number and Whole-Plant Glyphosate Resistance Level in Kochia scoparia.

PLoS ONE, 2016
Glyphosate-resistant (GR) Kochia scoparia has evolved in dryland chemical fallow systems throughout North America and the mechanism of resistance involves 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS) gene duplication.

Shikimate accumulation, glyphosate absorption and translocation in horseweed biotypes [PDF]

Planta Daninha, 2015
In Brazil, few research works on mechanisms of weed resistance to glyphosate have been conducted so far. Therefore, this research aimed to study analytical procedures determining the relation between the concentration of plant shikimate after glyphosate ...

Bt agave: why it is time to explore a new biotechnological frontier

Pest Management Science, EarlyView.
Drylands cover 41% of Earth, requiring sustainable crops. Agave, drought‐ and heat‐adapted, offers high‐value products with low water needs. Pests limit yield, yet Bacillus thuringiensis (Bt) Cry proteins, successful in other plants, remain unexploited in Agave.

A Trp574–Leu substitution confers resistance to three classes of acetolactate synthase inhibitors in Australian brome grass (Bromus diandrus)

Pest Management Science, EarlyView.
Target‐site based imidazolinone resistance in brome grass was found to be conferred by a mutation at position 574 in the ALS gene and to severely impact the efficacy of the herbicide Intervix®, a co‐formulation of imazamox and imazapyr. Abstract BACKGROUND Brome grass (Bromus diandrus) is a prevalent weed in southern Australian cropping regions which ...

Essential oils as bioherbicides: effects of orange and citronella oils on weed germination and early growth

Pest Management Science, EarlyView.
Essential oils from orange and citronella showed dose‐dependent inhibition of weed germination and early growth, highlighting their potential as bioherbicides and sustainable tools for integrated weed management. Abstract BACKGROUND Increasing selection of herbicide‐resistant weed biotypes has intensified the search for alternatives to the intensive ...

Field performance of MON 94637 and laboratory evidence supporting a Bt pyramiding strategy against key lepidopteran pests in Brazil

Pest Management Science, EarlyView.
A genetically modified soybean expressing multiple Cry proteins protects against key lepidopteran pests, consistently reducing larval damage and offering an effective resistance management option for soybean production in Brazil. Abstract BACKGROUND Pyramided Bt genes in crops have been widely adopted to delay insect resistance evolution worldwide. The

Multiple Resistance of Horseweed to Glyphosate and Paraquat and Its Control with Paraquat and Metribuzin Combinations

Agronomy, 2012
Greenhouse and field studies were conducted in 2007 and 2008 to investigate possible multiple-resistance of horseweed to paraquat and glyphosate, and to evaluate the effect of the addition of metribuzin to paraquat on control of paraquat-resistant ...

Effects of elevated CO2 and temperature on cocklebur (Xanthium strumarium L.) and its herbicide response

Pest Management Science, EarlyView.
Elevated CO2 promotes the growth of Xanthium strumarium while increasing its susceptibility to the systemic herbicide trifloxysulfuron‐sodium. The efficacy of the soil‐active herbicide fluometuron remains unaffected by changes in CO2 concentration and temperature.
