Book Description
Today, most growers use chemical weed management programs; however, a sole reliance on herbicides will place more resistance selection pressure on the weeds to which the herbicide is being applied. As herbicide resistance continues to grow and rob growers of yield, alternative weed control options are being sought to create complex integrated weed management programs to prolong the use of effective herbicides. Harvest weed seed control (HWSC) is a non-chemical practice that has been widely adopted in Australia due to herbicide resistance problems. In most cases, herbicide-resistant weeds that survive applications of herbicides produce viable seed that pass through the combine during crop harvest. HWSC focuses on lowering the soil seedbank by targeting weed seeds that pass through a combine at harvest. Experiments were conducted at the University of Arkansas in 2014 and 2015 to test the efficacy of HWSC on weeds in a soybean production system. Palmer amaranth, which has been deemed the most troublesome weed in the U.S., retains better than 97% of its seed at crop maturity, making it a viable option for seed capture and destruction during harvest. The efficacy of narrow-windrow burning was tested on two small- and large-seeded grass and broadleaf weeds (Palmer amaranth, barnyardgrass, johnsongrass, and pitted morningglory). All seed exposed to narrow-windrow burning treatments were killed. These data suggest that integration of HWSC into current weed management programs in soybean will be a valuable asset to lowering the soil seedbank and ultimately lowering the resistance selection pressure that is placed on herbicides due to lower weed densities.

Book Description
Herbicide resistance is of growing concern to wheat growers in the Pacific Northwest (PNW). Harvest weed seed control (HWSC) is an innovative, non-chemical approach developed in Australia that takes advantage of seed retention at maturity in many dominant annual weed species. Harvest weed seed control systems are focused on the management of chaff material in which most weed seed resides. Although HWSC has not been fully evaluated in the PNW, early work suggests that it can be an effective tool in an integrated weed management program. The choice of which particular HWSC system to use is dependent on the constraints of the cropping systems in which they are used and the specific needs of the grower. This publication discusses the various HWSC systems and their potential suitability for PNW wheat production systems across rainfall regions.

Book Description
Weed Management Handbook updates the 8th edition of Weed Control Handbook (1990). The change in the title and contents of the book from previous editions reflects both the current emphasis on producing crops in a sustainable and environmentally-friendly manner, and the new weed management challenges presenting themselves. This landmark publication contains cutting edge chapters, each written by acknowledged experts in their fields and carefully drawn together and edited by Professor Robert Naylor, known and respected world-wide for his knowledge of the area. The sequence of chapters included reflects a progression from the biology of weeds, through the underpinning science and technology relating to weed management techniques including herbicides and their application to crops, leading to principles of weed management techniques. Finally a set of relevant case studies describes the main management options available and addresses the challenges of reduced chemical options in many crops. Weed Management Handbook is a vital tool for all those involved in the crop protection / agrochemical industry, including business managers, horticultural and agricultural scientists, plant physiologists, botanists and those studying and teaching BASIS courses. As an important reference guide for undergraduate and postgraduate students studying horticultural and agricultural sciences, plant physiology, botany and crop protection, copies of the book should be available on the shelves of all research establishments and universities where these subjects are studied and taught. Weed Management Handbook is published for the British Crop Protection Council (BCPC) by Blackwell Publishing.

Book Description
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

Book Description
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
