Journal ArticleDOI
Interaction of Preventive, Cultural, and Direct Methods for Integrated Weed Management in Winter Wheat
Alexander Menegat,Anders Nilsson +1 more
TL;DR: A combination of stale seedbed preparation and herbicide treatment in autumn and spring was found to be synergistic, improving weed control efficacy significantly and moreover reducing the variability in control efficacy and hence the risk for weed control failure.

Nucleotide Diversity at Site 106 of EPSPS in Lolium perenne L. ssp. multiflorum from California Indicates Multiple Evolutionary Origins of Herbicide Resistance.
Elizabeth Karn,Marie Jasieniuk +1 more
TL;DR: It is likely that resistance to glyphosate in these 14 California populations of L. perenne derives from at least five evolutionary origins, indicating that adaptive traits can evolve repeatedly over agricultural landscapes.
Journal ArticleDOI
Trp574 substitution in the acetolactate synthase of Sinapis arvensis confers cross-resistance to tribenuron and imazamox.
TL;DR: Results strongly support that cross-resistance of 9 S. arvensis populations was due a point mutation of the als gene, which resulted in a less sensitive ALS enzyme, which meant all populations were susceptible to MCPA at the recommended rate.
Journal ArticleDOI
Inheritance of Glyphosate Resistance in Hairy Fleabane (Conyza bonariensis) from California
Miki Okada,Marie Jasieniuk +1 more
TL;DR: Variation in the pattern of inheritance and the level of resistance indicate that multiple resistance mechanisms may be present in hairy fleabane populations in California.

The complex genomic basis of rapid convergent adaptation to pesticides across continents in a fungal plant pathogen.
Fanny E. Hartmann,Fanny E. Hartmann,Tiziana Vonlanthen,Nikhil Kumar Singh,Megan C. McDonald,Megan C. McDonald,Andrew Milgate,Daniel Croll +7 more
TL;DR: A major fungal pathogen Zymoseptoria tritici causing serious losses on wheat and with fungicide resistance emergence across several continents is analysed and strong support for the “hotspot” model of resistance evolution with convergent changes in a small set of loci is found.

Crop losses to pests
TL;DR: Despite a clear increase in pesticide use, crop losses have not significantly decreased during the last 40 years, however, pesticide use has enabled farmers to modify production systems and to increase crop productivity without sustaining the higher losses likely to occur from an increased susceptibility to the damaging effect of pests.
Journal ArticleDOI
Environmental and Economic Costs of Nonindigenous Species in the United States
TL;DR: Aproximately 50,000 nonindigenous (non-native) species are estimated to have been introduced to the United States, many of which are beneficial but have caused major economic losses in agriculture, forestry, and several other segments of the US economy, in addition to harming the environment.

Evolution in Action: Plants Resistant to Herbicides
Stephen B. Powles,Qin Yu +1 more
TL;DR: Understanding resistance and building sustainable solutions to herbicide resistance evolution are necessary and worthy challenges to herbicides sustainability in world agriculture.
Journal ArticleDOI
The genetics of human adaptation: hard sweeps, soft sweeps, and polygenic adaptation.
TL;DR: This work argues for alternatives to the hard sweep model: in particular, polygenic adaptation could allow rapid adaptation while not producing classical signatures of selective sweeps, and discusses some of the likely opportunities for progress in the field.

Gene amplification confers glyphosate resistance in Amaranthus palmeri
Todd A. Gaines,Wenli Zhang,Dafu Wang,Bekir Bukun,Stephen T. Chisholm,Dale L. Shaner,Scott J. Nissen,William L. Patzoldt,Patrick J. Tranel,A. Stanley Culpepper,Timothy L. Grey,Theodore M. Webster,William K. Vencill,R. Douglas Sammons,Jiming Jiang,Christopher Preston,Jan E. Leach,Philip Westra +17 more
TL;DR: This work investigated recently discovered glyphosate-resistant Amaranthus palmeri populations from Georgia, in comparison with normally sensitive populations, and revealed that EPSPS genes were present on every chromosome and, therefore, gene amplification was likely not caused by unequal chromosome crossing over.
