Weed infestations are a concern for every farmer . Depending on the type of rice production system, farmers across Asia often contend with the same or similar weed species. This group of species is relatively small, but of great importance, and includes many of the "world's worst weeds." In this guide, we have tried to collect practical information about some of the most common weeds of rice in Asia. The guide contains information about the botany, ecology, herbicide resistance, and cultural control of these species in a short text that should be easy to use in the field. In addition, it includes pictures to aid in early and accurate species identification.

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.

Southeast Asia is highly diversified in terms of socio-ecosystems and biodiversity, but is undergoing dramatic environmental and social changes. These changes characterize the recent period and can be illustrated by the effects of the Green Revolution in the late 1960s and 1970s, to the globalization of trade and increasing agronomic intensification over the past decade. Biodiversity Conservation in Southeast Asia provides theoretical overviews and challenges for applied research in living resource management, conservation ecology, health ecology and conservation planning in Southeast Asia. Five key themes are addressed: origin and evolution of Southeast Asian biodiversity; challenges in conservation biology; ecosystem services and biodiversity; managing biodiversity and living resources; policy, economics and governance of biodiversity. Detailed case studies are included from Thailand and the Lower Mekong Basin, while other chapters address cross-cutting themes applicable to the whole Southeast Asia region. This is a valuable resource for academics and students in the areas of ecology, conservation, environmental policy and management, Southeast Asian studies and sustainable development.

Southeast Asia ranks among the most significant regions in the world for tracing the prehistory of human endeavor over a period in excess of two million years. It lies in the direct path of successive migrations from the African homeland that saw settlement by hominin populations such as Homo erectus and Homo floresiensis. The first Anatomically Modern Humans, following a coastal route, reached the region at least 60,000 years ago to establish a hunter gatherer tradition that survives to this day in remote forests. From about 2000 BC, human settlement of Southeast Asia was deeply affected by successive innovations that took place to the north and west, such as rice and millet farming. A millennium later, knowledge of bronze casting penetrated along the same pathways. Copper mines were identified and exploited, and metals were exchanged over hundreds of kilometers. In the Mekong Delta and elsewhere, these developments led to early states of the region, which benefitted from an agricultural revolution involving permanent ploughed rice fields. These developments illuminate how the great early kingdoms of Angkor, Champa, and Funan came to be, a vital stage in understanding the roots of the present nation states of Southeast Asia. Assembling the most current research across a variety of disciplines--from anthropology and archaeology to history, art history, and linguistics--The Oxford Handbook of Early Southeast Asia will present an invaluable resource to experienced researchers and those approaching the topic for the first time.

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
