Book excerpt: Excerpt from Tests of Chemical Means for the Control of Weeds: Report of Progress These conditions constitute a very serious menace to the agriculture of the state and were fully discussed at a meeting of the county horti cultural commissioners of California held at I Stanford University, July 26, 1915. The use of chemicals was frequently mentioned as a possible solution of the weed problem, butthe fact was brought out that very little information is available concerning their usefulness under California conditions. Following this meeting, Mr. William Wood, Los Angeles County Horticultural Commissioner, took up with the director of the agricultural experiment station at Berkeley the mat ter of an investigation of -methods of weed control by means of chemicals. It was suggested that a judicious use of chemicals might solve the problem of the control of those weeds which too often survive and increase in spite of expensive mechanical control measures. The suggested investigation was undertaken by the station in the fall of 1915, and the writer was assigned-to the Work. A review of the literature discloses the fact that the use of chemicals has simplified to some extent the solution of the problem of weed control on both agricultural and non-agricultural land in localities other than In one case at least, the use of chemicals for the destruction of weeds has become a common practice.9 Some of the experiments have demonstrated the usefulness of chemicals for the destruction of weeds on a large scale. Methods which have proved efficient elsewhere may also prove to be efficient here. The soil and climatic conditions of California, however, are so different from those of regions where the chemical method has proved satisfactory, that it is by no means certain that this will be the case. A study of the literature gave encouragement that weed pests might be controlled under local conditions if the conditions were carefully studied and the treatment made accordingly.

Book excerpt: This book presents the most up-to-date and comprehensive guide to the current and potential future state of weed science and research. Weeds have a huge effect on the world by reducing crop yield and quality, delaying or interfering with harvesting, interfering with animal feeding (including poisoning), reducing animal health and preventing water flow. They are common across the world and cost billions of dollars’ worth of crop losses year on year, as well as billions of dollars in the annual expense of controlling them. An understanding of weeds is vital to their proper management and control, without which the reduction in crop yields that they would cause could lead to mass starvation across the globe. Topics covered include weed biology and ecology, control of weeds and particular issues faced in their control. Authored and edited by internationally renowned scientists in the field all of whom are actively involved in European Weed Research Society working groups, this succinct overview covers all the relevant aspects of the science of weeds. Weed Research: Expanding Horizons is the perfect resource for botanists, horticultural scientists, agronomists, weed scientists, plant protection specialists and agrochemical company personnel.

Available in PDF, EPUB and Kindle. Book excerpt: Satisfying consumer needs through the production of healthy and nutritious agricultural products is a substantial challenge facing modern agriculture. However, agricultural production should be carried out with care for plant health, biological safety of products, and environmental safety while minimizing the risks to human health. Therefore, the implementation of agricultural practices while respecting these principles is very important for improving the quantity and quality of crops. Additionally, ecosystems have been altered as a result of human activities and climate change, resulting in the reduction of biodiversity and creation of new niches where pests can thrive. This is of particular importance in 2020, as the United Nations General Assembly declared this year as the International Year of Plant Health (IYPH), with “protecting plants, protecting life” as a leading subject. This Special Issue promotes the subject of plant health and emphasize the importance of preventing the spread of pests, including weeds, which cause substantial economic losses. Research articles cover topics related to the biology and harmfulness of weeds, particularly in connection with crop health, segetal weed communities and their biodiversity, and integrated methods of weed control. For this Special Issue, we welcome all types of articles, including original research, opinions, and reviews.

Available in PDF, EPUB and Kindle. Book excerpt: Aquatic plants continue to create problems associated with navigation, flood control, agriculture, irrigation and drainage, values of lands, conservation of wildlife and fisheries, and water resource supply. While much research is being done to find more effective and economic control measures, there is now a great need to apply known facts to achieve a measure of control by the means available. It is the purpose of this volume to provide a scientifically documented treatise of the known facts as they apply to the control of aquatic weeds in river basins and their allied waterways with particular emphasis on alligator weed and water hyacinth.
