DOWNLOAD EBOOKHere, at last, is a lavishly illustrated manual for ready identification of 299 common and economically important weeds in the region south to Virginia, north to Maine and southern Canada, and west to Wisconsin. Based on vegetative rather than floral characteristics, this practical guide gives anyone who works with plants the ability to identify weeds before they flower. - A dichotomous key to all the species described in the book is designed to narrow the choices to a few possible species. Identification can then be confirmed by reading the descriptions of the species and comparing a specimen with the drawings and photographs.- A fold-out grass identification table provides diagnostic information for weedy grasses in an easy-to-use tabular key.- Specimens with unusual vegetative characteristics, such as thorns, square stems, whorled leaves, or milky sap, can be rapidly identified using the shortcut identification table. The first comprehensive weed identification manual available for the Northeast, this book will facilitate appropriate weed management strategy in any horticultural or agronomic cropping system and will also serve home gardeners and landscape managers, as well as pest management specialists and allergists.

DOWNLOAD EBOOKManage Weeds on Your Farm: A Guide to Ecological Strategies provides you with in-depth information about dozens of agricultural weeds found throughout the country and the best ways of managing them. In Part One, the book begins with a general discussion of weeds: their biology, behavior and the characteristics that influence how to best control their populations. It then describes the strengths and limitations of the most common cultural management practices, physical practices and cultivation tools. Part Two is a reference section that describes the identification, ecology and management of 63 of the most common and difficult-to-control weed species found in the United States.

DOWNLOAD EBOOKWeeds 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.

DOWNLOAD EBOOKCommon Grasses, Legumes and Forbs of the Eastern United States: Identification and Adaptation presents photographic identification of the most important grassland, turf, and noncrop plants, and their seeds to facilitate quick identification in the field. Unlike many publications that focus solely on floral identification, this book emphasizes vegetative identification as well to allow for accurate plant identification year-round. The book includes 23 forage legumes, 61 grasses, and more than 100 nonleguminous forbs found in pastures and grasslands of Eastern United States. In addition to identification of important species, the book describes other key characteristics such as adaptation, favorable and unfavorable soil types, seasonal growth patterns, and toxicity. For plants harvested for hay or silage or by grazing, the book also discusses cutting and grazing management, quality factors, and potential yields. Through its practical approach and comprehensive structure, Common Grasses, Legumes and Forbs of the Eastern United States is a valuable reference for farm advisors, teachers and students of agronomy, and for anyone interested in the dynamic relationship between plants and agriculture. - Features full-color illustrations of both seed and plant, allowing for rapid identification at multiple stages of development - Presents various identification methods and use cases for over 180 plants - Details seasonal growth patterns and toxicity, as well as favorable and unfavorable soil types - Discusses cutting and grazing management

DOWNLOAD EBOOKCrop loss due to weeds has challenged agricultural managers since man began to develop the first farming systems. In the past century, however, much progress has been made to reduce weed interference in crop settings through effective yet mostly non-sustainable weed control strategies. With the commercial introduction of herbicides during the mid-1900's, advancements in chemical weed control tactics have provided efficient suppression of a broad range of weed species for most agricultural practices. Currently, with the necessity to design effective sustainable weed management systems, research has been pushing new frontiers on investigating integrated weed management options including chemical, mechanical as well as cultural practices. Author contributions to Weed Science present significant topics of research that examine a number of options that can be utilized to develop successful and sustainable weed management systems for many areas of crop production
