Chemical Treatment of Monodominant Cattail Stands In Semipermanent Wetlands: Duck, Invertebrate, and Vegetation Response
<p>The feasibility and effectiveness of glyphosate herbicide to create openings in dense monodominant stands of cattail in semi-permanent wetlands and the response of breeding and overwater nesting ducks and aquatic invertebrates to the chemical treatments were studied in northeastern South Dakota. …

Long-Term (24-Year) Effects of Harvest Disturbances on Ecosystem Productivity and Carbon Sequestration in Tupelo-Cypress Swamps in the Mobile-Tensaw River Delta
… cm (SKID), and 3. Helicopter harvest followed by glyphosate herbicide removal of all sprouts and seedbank regeneration for two years following harvest (GLYPH). An adjacent mature stand (94 years old) within the same original composition represented mature forest or pre-harvest reference conditions …

Investigating the heritability of resistance fueling copy number variation in glyphosate resistant Amaranthus palmeri
… to selection pressure from the environment. Herbicide is one selective agent targeting and promoting the evolution of resistance in agricultural weed populations. In Amaranthus palmeri, CNV of the EPSPS gene, the target of glyphosate herbicide, ranges from 1 to over 160 copies, and is the …

Method Development Using Laser Ablation And Solution Icpms And Their Application In Environmental Science And Forensic Provenance Studies
… The third project studied the effect of glyphosate herbicide on the mineral levels in glyphosate-resistent (GR) soybeans. Results from both greenhouse and field studies shono statistical difference in mineral concentrations between glyphosate-treated soybean and the control. This work …

Reduced Chemical Weed Control Options in Virginia for Corn and Turfgrass and Characterization of Sorghum halepense Expressing Multiple Resistance to Nicosulfuron and Glyphosate
… of one of agriculture's most pressing problems- herbicide resistance. Research conducted in Virginia sought to explore the effects of integrating multiple weed management tactics in corn and cool-season turfgrass. Additionally, research was conducted to confirm nicosulfuron and glyphosate …

Epigenetic Responses of Arabidopsis to Abiotic Stress
Weed resistance to control measures, particularly herbicides, is a growing problem in agriculture. In the case of herbicides, resistance is sometimes connected to genetic changes that directly affect the target site of the herbicide. Other cases are less straightforward where resistance arises …

Enhancement of Floral Species Richness in Glaciated Prairie Temporary Wetlands
… were a combination of (1) application of glyphosate herbicide (spray); (2) cutting and removal of vegetation (mow); (3) disturbance of soil using a field disc (disc); (4) application of seed purchased from a seed vendor (purchased seed); and (5) application of seed collected locally …

EFFECTS OF ANTHROPOGENIC SELECTION PRESSURE ON THE EVOLUTION OF A COMMON AGRICULTURAL WEED: DOES ADAPTATION COME WITH A DETECTABLE COST? A STUDY OF GLYPHOSATE-RESISTANT (GR) AND -SUSCEPTIBLE (GS) BIOTYPES OF Conyza canadensis
As the acreage of glyphosate-resistant (GR) cropping systems increases, so does the occurrence of herbicide-resistant weeds in the landscape. Biotypes of GR <italic>Conyza canadensis</italic> were first observed in Delaware, USA, in 2000. Since the first documentation of GR <italic>C. …

Regional whole plant and molecular response of Kochia scoparia to glyphosate
Globally, glyphosate (Roundup®) resistant weeds pose a serious challenge to modern agricultural practices that utilize glyphosate for weed control, including Roundup Ready® cropping regimes. Locally, glyphosate resistant Kochia scoparia have been identified throughout the central Great Plains, and …

Bioavailability of metolachlor and glyphosate in aerobic and anaerobic soils
Metolachlor and glyphosate are two extensively used herbicides in the USA and throughout the globe. Despite the prevalence of anaerobic wet situations in the soil, the predictive capability for the environmental fate and bioavailability of these herbicides is based primarily on well-drained soil …

Differential Response of a Virginia Common Lambsquarters (Chenopodium album) Collection to Glyphosate
… which exhibited a differential response to glyphosate treatments as compared to most other common lambsquarters. Plants from this site that survived glyphosate applications were collected in both 2002 and 2004. Greenhouse studies were conducted on F1, F2, and F3 progeny from this collection …
