Non-Chemical Weed Control is the first book to present an overview of plant crop protection against non-food plants using non-chemical means. Plants growing wild—particularly unwanted plants found in cultivated ground to the exclusion of the desired crop—have been treated with herbicides and chemical treatments in the past. As concern over environmental, food and consumer safety increases, research has turned to alternatives, including the use of cover crops, thermal treatments and biotechnology to reduce and eliminate unwanted plants. This book provides insight into existing and emerging alternative crop protection methods and includes lessons learned from past methodologies. As crop production resources decline while consumer concerns over safety increase, the effective control of weeds is imperative to insure the maximum possible levels of soil, sunlight and nutrients reach the crop plants. - Allows reader to identify the most appropriate solution based on their individual use or case - Provides researchers, students and growers with current concepts regarding the use of modern, environment-friendly weed control techniques - Presents methods of weed management—an important part of integrated weed management in the future - Exploits the knowledge gained from past sustainable weed management efforts

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

Invasive, alien plants are "uninvited guests" in most of Hawai'i's ecosystems. Native forests are invaded, and their precious native plant species are choked out. Extensive areas of pasture land have been colonized by plants that cannot be grazed. Weeds can be a fire hazard, and they can be painful impediments to access to natural areas. This book describes over 150 plants that are considered weeds under certain--if not, in some cases, most--circumstances. The plant types represented include trees, shrubs, vines and sprawlers, herbs, and grasses and their relatives. Most of the weeds covered are illustrated in color, both on the page where the weed is treated and on spreads of "thumbnail" images, grouped by growth habit category for convenience in quick identification. The text accompanying the photograph of each weed provides a detailed description, outlines its distribution and environmental impact in Hawai'i, and relates what is known about methods for managing it. Reprinted May 2021 with new cover.

It is important that scientists think about and know their history - where they came from, what they have accomplished, and how these may affect the future. Weed scientists, similar to scientists in many technological disciplines, have not sought historical reflection. The technological world asks for results and for progress. Achievement is important not, in general, the road that leads to achievement. What was new yesterday is routine today, and what is described as revolutionary today may be considered antiquated tomorrow. Weed science has been strongly influenced by technology developed by supporting industries, subsequently employed in research and, ultimately, used by farmers and crop growers. The science has focused on results and progress. Scientists have been--and the majority remain--problem solvers whose solutions have evolved as rapidly as have the new weed problems needing solutions. In a more formal sense, weed scientists have been adherents of the instrumental ideology of modern science. That is an analysis of their work, and their orientation reveals the strong emphasis on practical, useful knowledge; on know how. The opposite, and frequently complementary orientation, that has been missing from weed science is an emphasis on contemplative knowledge; that is, knowing why. This book expands on and analyzes how these orientations have affected weed science's development. - The first analytical history of weed science to be written - Compares the development of weed science, entomology and plant pathology - Identifies the primary founders of weed science and describes their role
