Download or read book Field Guide for the Biological Control of Weeds in the Northwest written by Rachel Winston and published by Government Printing Office. This book was released on 2017-12-13 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: This guide focuses on the most problematic weeds in eastern North America for which there are at least some biocontrol agents established and/or available. Multiple photos and descriptions of each weed included in this guide emphasize key identification traits and plant ecology. For each weed included in this guide, all biocontrol agents released or currently found in North America are described individually. Photos highlighting key identification features and damage are included. The release history, current status, and recommended use of each biocontrol agent are described in detail. Recommendations and current impact often vary between the US and Canada, therefore, the information is presented separately. Includes international code of best practices for classical biological control of weeds.

Download or read book Biological Control of Weeds written by M. H. Julien and published by Oxford University Press, USA. This book was released on 1998 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: Each entry details the target weed, control agent, year of first release, country of origin of agent, status and degree of control, research organisation involved, and key references. The catalogue format has been modified slightly from earlier editions to improve ease of use. The book provides an invaluable means of keeping track of the world situation, and is a handy reference for professionals, research workers and students interested in the biological control of weeds.

Download or read book Where Do Camels Belong written by Ken Thompson and published by . This book was released on 2015-05-07 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: Where do camels belong? In the Arab world may seem the obvious answer, but they are relative newcomers there. They evolved in North America, retain their greatest diversity in South America, and the only remaining wild dromedaries are in Australia. This is a classic example of the contradictions of 'native' and 'invasive' species, a hot issue right now, as the flip-side of biodiversity. We have all heard the horror stories of invasives, from Japanese knotweed that puts fear into the heart of gardeners to brown tree snakes that have taken over the island of Guam. But do we need to fear invaders? And indeed, can we control them, and do we choose the right targets? Ken Thompson puts forward a fascinating array of narratives to explore what he sees as the crucial question - why only a minority of introduced species succeed, and why so few of them go on to cause trouble. He discusses, too, whether our fears could be getting in the way of conserving biodiversity, and responding to the threat of climate change.

Download or read book Enduring Seeds written by Gary Paul Nabhan and published by University of Arizona Press. This book was released on 2002-10 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: As biological diversity continues to shrink at an alarming rate, the loss of plant species poses a threat seemingly less visible than the loss of animals but in many ways more critical. In this book, one of America's leading ethnobotanists warns about our loss of natural vegetation and plant diversity while providing insights into traditional Native agricultural practices in the Americas. Gary Paul Nabhan here reveals the rich diversity of plants found in tropical forests and their contribution to modern crops, then tells how this diversity is being lost to agriculture and lumbering. He then relates "local parables" of Native American agriculture—from wild rice in the Great Lakes region to wild gourds in Florida—that convey the urgency of this situation and demonstrate the need for saving the seeds of endangered plants. Nabhan stresses the need for maintaining a wide gene pool, not only for the survival of these species but also for the preservation of genetic strains that can help scientists breed more resilient varieties of other plants. Enduring Seeds is a book that no one concerned with our environment can afford to ignore. It clearly shows us that, as agribusiness increasingly limits the food on our table, a richer harvest can be had by preserving ancient ways. This edition features a new foreword by Miguel Altieri, one of today's leading spokesmen for sustainable agriculture and the preservation of indigenous farming methods.

This book was released on 2010-09-23 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fourteen informative papers dealing with their DNA, species interactions, adventiveness, host specificity, potential as boi-contol agents of weeds, chemical control, behaviour, their role in fungal pathogen epidemiology, influence in forests and on ornamentals, collecting and mounting techniques and their interaction with crops are presented here. This is an extensive and valuable contribution to eriophyoid science and a must for present and future researchers in this field.

Download or read book Weed Physiology written by Stephen O. Duke and published by CRC Press. This book was released on 2018-01-18 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: Volume 2 deals with the mechanisms of herbicide action and of resistance and tolerance to herbicides. The first five chapters of this volume cover the effects of herbicides and adjuvants on the physiology of plants. Professor Black‘s chapter begins by covering the effects of herbicides on photosynthesis, including photosynthetic assimilation of nitrogen, sulfur, and phosphorus. This is followed by Dr. Morelands chapter on herbicide interactions with plant respiration. The third chapter by Professor Bartels deals with the effects of herbicides on chloroplast and cellular development with emphasis on correlating physiological information with ultrasound effects.
