Available in PDF, EPUB and Kindle. Book excerpt: Edited by a recognized leader in the field, Herbicide-Resistant Crops is the first book to cover all of the issues related to the controversial topic of herbicide-resistant crops. It provides extensive discussions of the modern biotechnological methods that have been used to develop such crops, and reviews the implications - both positive and negative - of developing crops that are resistant to herbicides. The creation and anticipated applications of specific herbicide-resistant crops are also discussed. In addition, the book covers the potential impact of herbicide-resistant crops on weed management practices and the environment, and presents issues related to the regulation and economics of these crops. The editor has brought together a diverse group of professionals, representing the several distinct areas impacted by the new technology of herbicide-resistant crops. The wide range of viewpoints presented in this book creates a balanced and complete survey, providing a notable contribution to the literature.

Download or read book Effects of Glyphosate on Weed Management and Reproductive Biology of Glyphosate-Resistant Corn written by and published by . This book was released on 2002 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Field studies were conducted from 2000 to 2002 to evaluate crop tolerance, weed control, grain yield, and net returns in glyphosate-resistant corn with various herbicide systems. Weed management systems evaluated various preemergence (PRE) and postemergence (POST) herbicide options. Glyphosate formulations did not influence crop injury, weed control, or grain yield in either study. Effective annual grass control was not achieved with any PRE herbicide system. However, PRE herbicide treatment plus any glyphosate treatment controlled goosegrass, large crabgrass, and Texas panicum> 86%. Regardless of PRE herbicide options, any POST glyphosate treatment controlled common ragweed and common lambsquarters at least 88 and 89%, respectively. Ipomoea spp. were controlled at least 88% with a PRE herbicide fb glyphosate EPOST alone, glyphosate sequentially, or in EPOST mixture with either halosulfuron or mesotrione. The highest yielding herbicide systems used glyphosate applied once or twice. Net returns were highest for glyphosate weed management systems. Experiments conducted in the North Carolina State University Phytotron greenhouse and three field locations in 2002 determined the effect of 1.12 kg ai/ha of glyphosate at various application timings on pollen viability and seed set in two types (GA21 and NK603) of glyphosate-resistant corn. Regardless of hybrid, pollen viability was reduced in phytotron and field studies with glyphosate treatments applied POST at the V6 stage or later. Scanning and transmission electron microscopy indicated distinct morphological alterations and large vacuoles and lower starch accumulation associated with later glyphosate treatments that caused pollen viability reductions. Although glyphosate negatively influenced pollen viability, pollination and seed set were not influenced. Enzyme-linked immunoabsorbent assay examined CP4-EPSPS expression in DKC 64-10 (NK603) at anthesis and showed the greatest amount in pollen with progressively less i.

Available in PDF, EPUB and Kindle. Book excerpt: Cover crops slow erosion, improve soil, smother weeds, enhance nutrient and moisture availability, help control many pests and bring a host of other benefits to your farm. At the same time, they can reduce costs, increase profits and even create new sources of income. You¿ll reap dividends on your cover crop investments for years, since their benefits accumulate over the long term. This book will help you find which ones are right for you. Captures farmer and other research results from the past ten years. The authors verified the info. from the 2nd ed., added new results and updated farmer profiles and research data, and added 2 chap. Includes maps and charts, detailed narratives about individual cover crop species, and chap. about aspects of cover cropping.

This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of herbicide weed control has been an integral part of farm management for several decades due to being an efficient and cost-effective alternative to mechanical weed control management. However, repeated use of broad spectrum herbicides has resulted in herbicide resistance in several weed species (Norsworthy et al., 2012). Although the indiscriminate use of herbicides has been linked to the quick and widespread adoption of herbicide resistant crop species (Fernandez-Cornejo et al., 2014), research indicates that herbicide resistance predated the introduction of bio-tech crops by several decades (WSSA, 2016). By the time that USDA began tracking the adoption of biotech soybean production in 2000, over half of US acreage were planted to herbicide-tolerant varieties and reached over 90% within 7 years (USDA NASS) (Figure 1). By 2013, 90% of corn and soybean acreage were planted to bio-tech cultivars including herbicide-tolerate only and stacked genes (Figure 1). Currently, 470 unique cases of herbicide resistance have been documented (Heap, 2016). Multiple herbicide-resistant weed species causes additional concern due to reduced herbicide options and increased weed control costs. Multiple herbicide resistance has been confirmed in economically important weeds including Palmer amaranth (Amaranthus palmeri) (Nandula et al. 2012), waterhemp (Amaranthus tuberculatus Sauer) (Bell et al., 2013), horseweed (Conyza canadensis L. Cronq.) (Davis et al. 2009), rigid ryegrass (Lolium rigidum Gaudim) (Owen et al. 2014), and kochia (Kochia scoparia (L.) Schrad.) (Foes et al. 1999) (see Heap, 2016, for more details on herbicide resistance weeds).

Download or read book Biology and Management of Problematic Crop Weed Species written by Bhagirath Chauhan and published by Elsevier. This book was released on 2021-09-04 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: Weeds are the main biological constraint to crop production throughout the year. Uncontrolled weeds could cause 100% yield loss. In Australia, the overall cost of weeds to Australian grain growers was estimated at AU$ 3.3 billion annually. In terms of yield losses, weeds amounted to 2.7 million tonnes of grains at a national level. In the USA, weeds cost US$ 33 billion in lost crop production annually. In India, these costs were estimated to be much higher (US$ 11 billion). These studies from different economies suggest that weeds cause substantial yield and economic loss. Biology and Management of Problematic Weed Species details the biology of key weed species, providing vital information on seed germination and production, as well as factors affecting weed growth. These species include Chenopodium album, Chloris truncata and C. virgate, Conyza bonariensis and C. canadensis, Cyperus rotundus, and many more. This information is crucial for researchers and growers to develop integrated weed management (IWM) strategies. Written by leading experts across the globe, this book is an essential read to plant biologists and ecologists, crop scientists, and students and researchers interested in weed science. Provides detailed information on the biology of different key weed species Covers weed seed germination and emergence Presents the factors affecting weed growth and seed production

This book was released on 1997-05-31 with total page 366 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent decades, repeated use of herbicides in the same field has imposed selection for resistance in species that were formerly susceptible. On the other hand, considerable research in the private and public sectors has been directed towards introducing herbicide tolerance into susceptible crop species. The evolution of herbicide resistance, understanding its mechanisms, characterisation of resistant weed biotypes, development of herbicide-tolerant crops and management of resistant weeds are described throughout the 36 chapters of this book. It has been written by leading researchers based on the contributions made at the International Symposium on Weed and Crop Resistance to Herbicides held at Córdoba, Spain. This book will be a good reference source for research scientists and advanced students.
