Weeds 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.

Creeping Bentgrass Management presents a difficult management problem throughout the summer season. This complex dilemma is related to numerous and often interrelated factors such as: extreme air and soil temperatures, drought or excessively wet soils, dense thatch or organic mats, mechanical and other physical stresses, improper management practices, the misuse of chemicals, and other physical stresses. The goal of this useful manual--complete with helpful color photographs--is to give golf course superintendents practical tools to better understand the many stress factors that contribute to the creeping bentgrass decline complex. It will help you pinpoint problems, and implement cultural and chemical solutions to maintain the integrity of your course.

A comprehensive reference-cum-textbook on fundamentals and principles of weed science. Includes updated information on newer approaches (ecophysiological and biological) in weed management, newer herbicides, bioherbicides, herbicide action mechanisms and transformations in plants, herbicide persistence and behaviour in soil and environment, and interaction of herbicide with other aerochemicals.

References, suppliers, and a comprehensive index make this book indispensable to growers, farm advisors, IPM scouts, pesticide applicators, pest control advisors, and students. A complete sourcebook for bulbs, cut flowers, potted flowering plants, foliage plants, bedding plants, ornamental trees, and shrubs as grown in the field, greenhouse, and nursery.--COVER.

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
