Book Description
The book entitled “Identification of Weeds and their Control Measures” contains three chapters regarding Identification characteristics, management methods as well as medicinal values of weeds. The first chapter i.e. Identification of weeds contains coloured photographs of important weeds of crops, wasteland and aquatic situations. In this chapter detailed morphological characters of weeds, association with different crops, their dispersal mechanism and growing season etc. are given. Also, important morphological characters pertaining to different weed species i.e. plant height, leaf type, root system, type of stem, growing season, branching habits, flower type and colour, fruits/seeds, habitat, means of propagation etc. are given. Control measures of individual weeds by different weed control methods is also given in detail. In second chapter, control of different weeds species i.e. grass, broad leaf and sedges growing in different crops of kharif and rabi season with different selective herbicides along with their doses and time of application has been given. In addition to field crops, control of weeds in medicinal, spice and aromatic crops as well as fodder and vegetable crops has also been given. In the third chapter, the medicinal value of important weeds/plant parts which can be used to cure different human as well as animal diseases has been discussed.

Book Description
This encyclopedic yet easy-to-use 2-volume set covers 262 individual entries, including a full description of 451 species and another 361 plants compared as similar species, representing 63 plant families. 13 shortcut identification tables for groups that share similar, unusual, or relatively uncommon characteristics. 2 grass identification keys - a key to all characteristics including inflorescences and reproductive parts and a key to vegetative characteristics only. 67 tables comparing important characteristics of difficult-to-distinguish weedy species. Color photos of over 700 weeds including seeds, seedlings, flowers, and mature plants. Appendix of non-native plants rarely or occasionally naturalized in California. Glossary of botanical terms. Bibliography of some of the most pertinent publications. Index to common names, scientific names, and synonyms. Each entry describes the plant category, family name, common name, and synonyms along with a summary of the important aspects of the plant’s life cycle, size, growth form, impact, method of introduction, and toxicity. You'll also find a description of the seedling, mature plant, roots and underground structures, flowers, fruits and seeds, spikelets and florets, spore-bearing structures, and post senescence characteristics for each entry. Also includes a description of the habitat where each is typically found and distribution in California, other states, and worldwide, along with maximum elevation at which the species is found. Rounding out each entry is a description of the methods of reproduction, seed dispersal, germination requirements and conditions, seed survival and longevity, early establishment characteristics and requirements, cultural practices and management options that have proven effective or ineffective in controlling infestations, and a notation of the species' inclusion on federal or state noxious weed lists.

Book Description
Manage Weeds on Your Farm: A Guide to Ecological Strategies provides you with in-depth information about dozens of agricultural weeds found throughout the country and the best ways of managing them. In Part One, the book begins with a general discussion of weeds: their biology, behavior and the characteristics that influence how to best control their populations. It then describes the strengths and limitations of the most common cultural management practices, physical practices and cultivation tools. Part Two is a reference section that describes the identification, ecology and management of 63 of the most common and difficult-to-control weed species found in the United States.

Book Description
This book introduces readers to nearly 600 common weeds. In addition to essential information, each chapter includes photos for a specific type of weed to show its morphology in different growth periods, such as seedling, root, flower, fruit, and mature plant. The book also discusses control measures, including agricultural, chemical, physical, biological, and comprehensive methods. The Volume2 mainly focuses on fern and 216 species of weeds of magnoliids or dicotyledoneae. With the development of society and economics, weeds have become a recurring problem. In particular, the exotic, invasive, and quarantine weeds have spread dramatically and rapidly. On the other hand, many people, even those who are engaged in weed control, do not (or cannot) distinguish between weeds. Thus there is significant demand for illustrations of weed morphologies, as well as information on their control measures. This book offers a valuable, practical guide for all those working in the fields of crop cultivation, plant protection and quarantine management.

Her unique approach, which she calls “horticultural how-to and woo-woo,” is a blend of vital information you need to memorize and intuitive steps you must simply feel and surrender to. In A Way to Garden, Roach imparts decades of garden wisdom on seasonal gardening, ornamental plants, vegetable gardening, design, gardening for wildlife, organic practices, and much more. She also challenges gardeners to think beyond their garden borders and to consider the ways gardening can enrich the world. Brimming with beautiful photographs of Roach’s own garden, A Way to Garden is practical, inspiring, and a must-have for every passionate gardener.

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
