Abstract Weeds are attractive models for basic and applied research due to their impacts on agricultural systems capacity swiftly adapt in response anthropogenic selection pressures. Currently, a lack of genomic information precludes elucidate the genetic basis rapid adaptation important traits like herbicide resistance stress tolerance effect evolutionary mechanisms wild populations. The International Weed Genomics Consortium is collaborative group scientists focused developing resources...
Abstract Downy brome, feral rye, and jointed goatgrass are problematic winter annual grasses in central Great Plains wheat production. Integrated control strategies needed to manage reduce selection pressure exerted on these weed populations by the limited herbicide options currently available. Harvest weed-seed (HWSC) methods aim remove or destroy seeds, thereby reducing seed-bank enrichment at crop harvest. An added advantage is potential herbicide-resistant seeds that more likely be...
Abstract The International Weed Genomics Consortium is a collaborative group of researchers focused on developing genomic resources for the study weedy plants. Weeds are attractive systems basic and applied research due to their impacts agricultural capacity swiftly adapt in response anthropogenic selection pressures. Our goal use information develop sustainable effective weed control methods provide insights about biotic abiotic stress tolerance assist crop breeding. Here, we outline under...
Biochar and vinasse are by-products of biofuel production that can be used as soil amendments. However, their addition to the might affect PRE herbicide activity. Although studies have shown biochar has a high adsorption capacity, there is little information available about effect on weed control especially under field conditions. Therefore, objective this study was determine influence application atrazine pendimethalin availability activity in vitro In herbicidal activities were not...
Abstract A dicamba-resistant population of kochia ( Bassia scoparia ) identified in Colorado, USA 2012 was used to generate a synthetic mapping that segregated for dicamba resistance. Linkage associating injury with genotype derived from restriction-site-associated DNA sequencing single locus the genome associated resistance on chromosome 4. mutant version Auxin/Indole-3-Acetic Acid 16 AUX/IAA16 ; gene previously implicated kochia) found near middle this resistant plants. Long read plants...
Vinasse and biochar are by-products of biofuel production that can be used as sources nutrients to crops or soil amendments improve quality. Despite the recent interest in vinasse effects on properties, little is known about their effect weed communities. We hypothesized addition could affect seed germination growth, different species would show responses these amendments. Therefore, objectives this study were determine growth Palmer amaranth, sicklepod, southern crabgrass. The was conducted...
Abstract Background Early detection of herbicide resistance in weeds is crucial for successful implementation integrated weed management. We conducted a survey the winter annual grasses feral rye ( Secale cereale ), downy brome Bromus tectorum and jointed goatgrass Aegilops cylindrica ) from Colorado wheat production areas to imazamox quizalofop. Results All samples were susceptible imazamox. Out 314 field collected samples, we identified three populations (named A, B, C) that resistant....
Biochar can potentially provide better conditions in the soil to increase plant growth. However, research has shown that weed species show minimal changes germination and emergence patterns with addition of biochar. Regardless, if biochar is used field it important monitor for populations. This especially because decrease herbicide efficacy. 3-page fact sheet was written by Neeta Soni, Ramon G. Leon, John E.
