Excerpt from Agents for Biological Control of Purple Nutsedge, Cyperus Rotundus L: The Genus Bactra Stephens (Lepidoptera; Tortricidae; Olethreutinae) As a Major Source, With Emphasis on the Biology and Potential Use of Bactra Verutana Zeller Among the more widespread weeds in the world are two perennial herbs that propagate primarily by means of underground tubers. These plants are in the sedge family, Cyperaceae, and are purple nutsedge, Cyperus rotundus L., and yellow nutsedge, C. Esculentus L. Because these weeds are difficult to control, Holm et al. (1977) rated purple nutsedge as the world's worst weed and yellow nutsedge as the 16th worst. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

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

Responsible for a high proportion of the world's crop losses, weedstake away food that the world badly needs. They decrease thequality and quantity of vegetable fibers, wool, and hides, andinterfere with fishing, irrigation, hydroelectric power production,and the movement of shipping vessels. In order to recognize thetrue magnitude of the weed problem, and to be better equipped todesign effective weed control methods, it is vital to identify andlearn as much as possible about the many different species of thisdestructive agricultural predator. The culmination of four decades of global research, World Weedspresents comprehensive and up-to-date information on over 100weeds--addressing recent changes in such areas as crop tillagemethods, herbicide use, and agricultural runoff. This monumentalwork, featuring a wealth of original data from the authors,provides extensive coverage of the known biology of each species.Each entry contains a full botanical description, plus importantdetails on habitat requirements and distribution, seed production,ecology, physiology, crop impact, and more. Generously suppliedwith dozens of unique illustrations and species distribution mapscovering over 100 countries, this definitive resource boasts anextensive multilingual index of common names, and a massivebibliography with over 3,000 references to facilitate furtherreading and research. World Weeds is a truly masterful referencethat will be celebrated by weed and crop scientists, botanists, andothers for years to come.

The book presents discussions on: Biology and ecology of major troublesome weeds infesting rice, wheat, corn, soybean, focusing on different cropping patterns in both tropical and temperate cropping systems and science-based weed management practices involving chemical, non-chemical, biological, integrated methods. Herbicides used, with their most recent classification, identification of new target sites, mechanisms and modes of action and how and why weeds evolve resistance to herbicides. New concepts, new paradigms and new technologies to manage evolution of resistance to herbicides including weed genomics, bioherbicides and allelochemicals. Highly recommended for students, teachers, researchers, agronomists, horticulturists, crop physiologists, and crop protection specialists in tropical and temperate agricultural systems, particularly in areas where major tropical weeds are posing potential threats to temperate agricultural systems.
