Book excerpt: Provides a comprehensive overview of the role of cotton in the economy and cotton production around the world This book offers a complete look at the world’s largest fiber crop: cotton. It examines its effect on the global economy—its uses and products, harvesting and processing, as well as the major challenges and their solutions, recent trends, and modern technologies involved in worldwide production of cotton. Cotton Production presents recent developments achieved by major cotton producing regions around the world, including China, India, USA, Pakistan, Turkey and Europe, South America, Central Asia, and Australia. In addition to origin and history, it discusses the recent advances in management practices, as well as the agronomic challenges and the solutions in the major cotton producing areas of the world. Keeping a focus on global context, the book provides sufficient details regarding the management of cotton crops. These details are not limited to the choice of cultivar, soil management, fertilizer and water management, pest control, cotton harvesting, and processing. The first book to cover all aspects of cotton production in a global context Details the role of cotton in the economy, the uses and products of cotton, and its harvesting and processing Discusses the current state of cotton management practices and issues within and around the world’s cotton producing areas Provides insight into the ways to improve cotton productivity in order to keep pace with the growing needs of an increasing population Cotton Production is an essential book for students taking courses in agronomy and cropping systems as well as a reference for agricultural advisors, extension specialists, and professionals throughout the industry.

This book was released on 2014 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: The evolution of herbicide-resistant weed species in cotton production has created a need for new herbicide technology tools. Herbicide technologies not classified as genetically modified by recombinant DNA can provide tools with less associated registration and development costs and regulatory and market barriers. Research herein aims to advance herbicide crop tolerance through improvement and genetic analysis of mutation derived herbicide tolerance in cotton. Germplasm exhibiting elevated tolerance to the imidazolinone class of herbicides has been previously identified after mutagenesis with ethyl methanesulfonate (EMS). However, the physiological basis, genetic behavior, and potential for herbicide tolerance improvement are not fully understood and studies were designed to elucidate these factors. Three lines (EM4-3-1-1, EM4-3-1-2, and SCM3-4-3-1) show high levels of imazamox tolerance. Data indicate that yield for all EMS treated lines was equal to or greater than their respective non-EMS treated cultivar. EMS treatment had no adverse effects on other cotton fiber properties. In 2012, levels of imazamox herbicide injury were seen at 14 days after application (DAA) ranging from 25-34 per cent. A greater level of injury was observed in 2013 ranging from 30-37% 7 DAA, and from 60-68% 14 DAA. Injury was transient throughout both growing seasons. Acetolactate synthase (ALS) gene sequencing characterized a mutation at Ala122 that is classified as conferring tolerance to imidazolinone herbicides, but was inconsistent in lines evaluated. Sequencing also revealed lines that have a truncated form of the protein in this region that may inhibit imidazolinone binding to the ALS protein. Chi-square analysis indicated this trait behaves in a simple, dominant fashion. Data from parent-offspring regression analysis indicated moderate correlation between parents and F2 progeny (53%). Correlation is relatively high between F2 and F33 progeny (84%) and demonstrates a strong relationship between these generations. Gain from selection indicates a 13.6% improvement in herbicide tolerance, lending to low progress from selection. These studies have shown that non-transgenic breeding methods can confer and improve imidazolinone herbicide tolerance in cotton, though levels of imidazolinone herbicide injury remained commercially unacceptable.

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Field studies were conducted to evaluate control of Amaranthus species and other weeds in corn and cotton. In corn, Palmer amaranth control was at least 90% with preemergence applications of fluthiacet-methyl plus pyroxasulfone, atrazine plus either acetochlor, alachlor, dimethenamid-P, S-metolachlor, or S-metolachlor plus mesotrione, saflufenacil plus dimethenamid-P, and S-metolachlor plus mesotrione. When using postemergence herbicides applied to Palmer amaranth less than 5 cm tall, atrazine, prosulfuron, and topramezone alone or the combinations of atrazine plus S-metolachlor plus glyphosate, diflufenzopyr plus dicamba, dimethenamid plus glyphosate, halosulfuron-methyl plus dicamba, mesotrione plus S-metolachlor plus glyphosate, pyroxasulfone plus glyphosate, and thiencarbazone-methyl plus tembotrione provided at least 91% control. In cotton, pyrithiobac applied preemergence resulted in no greater than 63% of control of Palmer amaranth and common waterhemp at the early season rating. Pendimethalin applied preemergence provided varied levels of control of common waterhemp. Trifluralin, applied preplant incorporated, consistently provided at least 86% or greater control of both species. A decreased level of control of both Palmer amaranth and common waterhemp was observed with pendimethalin applied preemergence followed by pyrithiobac-applied early postemergence and followed by glufosinate applied mid-post. Systems which included an early postemergence and mid-postemergence application of glyphosate plus 2,4-d choline provided at least 94% season-long Palmer amaranth control.

This book was released on 2017-01-28 with total page 607 pages. Available in PDF, EPUB and Kindle. Book excerpt: Genetically engineered (GE) crops were first introduced commercially in the 1990s. After two decades of production, some groups and individuals remain critical of the technology based on their concerns about possible adverse effects on human health, the environment, and ethical considerations. At the same time, others are concerned that the technology is not reaching its potential to improve human health and the environment because of stringent regulations and reduced public funding to develop products offering more benefits to society. While the debate about these and other questions related to the genetic engineering techniques of the first 20 years goes on, emerging genetic-engineering technologies are adding new complexities to the conversation. Genetically Engineered Crops builds on previous related Academies reports published between 1987 and 2010 by undertaking a retrospective examination of the purported positive and adverse effects of GE crops and to anticipate what emerging genetic-engineering technologies hold for the future. This report indicates where there are uncertainties about the economic, agronomic, health, safety, or other impacts of GE crops and food, and makes recommendations to fill gaps in safety assessments, increase regulatory clarity, and improve innovations in and access to GE technology.

This book was released on 2000-08-23 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explores the risks and benefits of crops that are genetically modified for pest resistance, the urgency of establishing an appropriate regulatory framework for these products, and the importance of public understanding of the issues. The committee critically reviews federal policies toward transgenic products, the 1986 coordinated framework among the key federal agencies in the field, and rules proposed by the Environmental Protection Agency for regulation of plant pesticides. This book provides detailed analyses of: Mechanisms and results of genetic engineering compared to conventional breeding for pest resistance. Review of scientific issues associated with transgenic pest-protected plants, such as allergenicity, impact on nontarget plants, evolution of the pest species, and other concerns. Overview of regulatory framework and its use of scientific information with suggestions for improvements.
