Available in PDF, EPUB and Kindle. Book excerpt: Herbicides are the dominant technology and the most effective weed control tools ever developed that are used for the control of weeds that infest crops. Over the last several decades, in situations of intense herbicide usage, there have been many examples of the evolution of weed populations resistant to herbicides. Weed adaptations to management tactics, including biochemical mimicry in the form of evolved resistance to the herbicides used for weed control, have increased rapidly throughout agriculture and now threaten global food security. Nowadays, expended space of research activities remains to focus on the herbicide resistance to weeds and crops. The authors of Herbicide Resistance in Weeds and Crops cover various issues regarding the present relevant research.

Download or read book Evolution of Herbicide Resistance in Lolium Perenne Ssp Multiflorum Populations written by Elizabeth Karn and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Herbicide-resistant weeds provide a unique system in which to study the evolution of adaptive traits. The selection pressures, adaptive traits, and often the underlying basis for herbicide resistance are typically known, allowing for studies of adaptive variation across large agricultural landscapes that vary in selection pressures and intensities over space and time. In the last several years, populations of Lolium perenne ssp. multiflorum (Lam.) in orchards and vineyards of northwest California were suspected of evolving resistance to the herbicides glyphosate and glufosinate. Earlier work identified that a non-synonymous mutation in 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS) gene is responsible for glyphosate resistance in the Central Valley of California. The research presented in this dissertation characterizes phenotypes resistant to glyphosate and glufosinate and examines the evolution of glyphosate resistance in northwest California populations of L. perenne ssp. multiflorum using neutral genetic diversity and adaptive genetic variation, to gain a greater understanding of contemporary adaptive evolution across landscapes. In Chapter 1, I measure the frequency of glyphosate-resistant and glufosinate-resistant individuals in 14 populations of L. perenne across three screening times and measure the population-average level of resistance in selected populations. The analysis demonstrates that while both glyphosate- and glufosinate-resistant individuals are present in northwest California with distinct mechanisms conferring resistance to each herbicide, these resistance phenotypes are variable over time, especially for glufosinate. In Chapter 2, using microsatellite genetic variation at 12 loci in the sampled individuals, I show that California L. perenne contains high genetic diversity and admixture across populations, with a potential for spread of glyphosate resistance through gene flow. In Chapter 3, I genotype adaptive genetic variation in the sampled individuals and identified four distinct glyphosate-resistant EPSPS alleles at codon site 106, indicating multiple evolutionary origins of glyphosate resistance in the region, although resistance in some populations cannot be explained by EPSPS mutations at site 106. Together, these results demonstrate that the evolution of adaptive traits across a landscape can be quite complex, with variable phenotypes conferred by multiple independent evolutionary origins of the same adaptive trait with subsequent spread through gene flow.

Download or read book Herbicides and Their Mechanisms of Action written by Andrew H Cobb and published by Blackwell. This book was released on 2000-12-18 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: Herbicides and their Mechanisms of Action highlights issues in herbicide selectivity. Developed with the input of authors from both academia and industry, this volume delivers a comprehensive and up-to-date treatment of the operation of the selectivity mechanisms of herbicides. Even more, the book discusses real-world effects of herbicides, and the results herbicides bring to bear on the environment. The authors emphasize applied aspects of the subject and concentrate on the developments of the last decade, making the book both practical and timely. With the wide variety of herbicides now available for the selective control of weed growth, it is imperative that scientists acquire a detailed understanding of the scientific bases of these herbicides. Indeed, the most recently developed herbicides work by inhibiting the enzyme systems of specific herbs, thereby retarding the growth of those herbs. For maximum effectiveness it becomes crucial that the active ingredients of these herbicides be efficiently delivered on the desired targets. Providing a state-of-the-art appraisal of this important subject, Herbicides and their Mechanisms of Action is the ideal resource for virtually all researchers and professionals involved in the development, administration, and regulation of herbicides.
Download or read book Characterization of Herbicide Resistance in Lolium Multiflorum Populations from California and Oregon written by Caio Augusto De Castro Grossi Brunharo and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Italian ryegrass (Lolium multiflorum) is a troublesome weedy species spread throughout the United States, competing for light, water and nutrients with crops. Its control has been chiefly dependent on herbicides due to their effectiveness and practicality. As result of heavy selection pressure, herbicide-resistant populations of Italian ryegrass have been selected in California and Oregon trees and vines. Recently, poor control of Italian ryegrass with paraquat was reported by orchard managers in California, whereas glufosinate-resistant populations were reported in Oregon. We hypothesize that the low paraquat efficacy observed in a California population is due to the selection of a paraquat-resistant biotype. We also hypothesized that non-target-site mechanisms of resistance were selected in glufosinate-resistant Italian ryegrass populations from Oregon. Greenhouse, field and laboratory experiments were carried out to characterize herbicide-resistant Italian ryegrass populations from California. Laboratory experiments were conducted to characterize the resistance to glufosinate in Oregon Italian ryegrass populations. Greenhouse dose-response experiments confirmed the presence of paraquat resistance in an Italian ryegrass population from California, with multiple resistance to clethodim and glyphosate. Glyphosate resistance is due to amino acid substitutions in the EPSPS at position 106. Field experiments with PRE herbicides indicated that tankmixes containing indaziflam and flumioxazin can provide adequate L. multiflorum control up to 150 days after treatment. Resistance to paraquat likely involves vacuolar sequestration of the herbicide. Laboratory experiments with Oregon Italian ryegrass populations indicate that metabolism of glufosinate is involved in the resistance mechanism. These results add generally to the body of knowledge of herbicide resistance in ryegrass and should influence how multiple herbicide-resistant populations are managed in trees and vines of the western US.
Download or read book Weed Biology and Management written by Inderjit and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 550 pages. Available in PDF, EPUB and Kindle. Book excerpt: Weeds hold an enigmatic and sometimes-controversial place in agriculture, where they are generally reviled, grudgingly tolerated, and occasionally admired. In most cases, growers make considerable effort to reduce the negative economic impact of weeds because they compete with crops for resources and hinder field operations, thereby affecting crop productivity and quality, and ultimately the sustainability of agriculture. Weed control in production agriculture is commonly achieved through the integration of chemical, biological, and mechanical management methods. Chemicals (herbicides) usually inhibit the growth and establishment of weed plants by interfering with various physiological and biochemical pathways. Biological methods include crop competition, smother crops, rotation crops, and allelopathy, as well as specific insect predators and plant pathogens. Mechanical methods encompass an array of tools from short handled hoes to sophisticated video-guided robotic machines. Integrating these technologies, in order to relieve the negative impacts of weeds on crop production in a way that allows growers to optimize profits and preserve human health and the environment, is the science of weed management.
