Plant parasitic nematodes are costly burdens of crop production, causing an estimated US$80 - 118 billion per year in damage to crops. They are associated with nearly every important agricultural crop, and are a significant constraint on global food security. Regulations on the use of chemical pesticides have resulted in growing interest in alternative methods of nematode control. Future changes in climate, cropping systems, food habits, as well as social and environmental factors also affect the options for nematode control. Taking a systematic crop by crop approach, this book: Outlines the economic importance of specific plant parasitic nematode problems on the major food and industrial crops. Presents the state-of-the-art management strategies that have been developed to reduce specific nematode impacts, and outlines their limitations. Contains case studies to illustrate impact in the field. Aims to anticipate future changes in nematode disease pressure that might develop as a result of climate change, and new cropping systems.

This edited book provides knowledge about hemicelluloses biorefinery approaching production life cycle, circular economy, and valorization by obtaining value-added bioproducts and bioenergy. A special focus is dedicated to chemical and biochemical compounds produced from the hemicelluloses derivatives platform. Hemicelluloses are polysaccharides located into plant cell wall, with diverse chemical structures and properties. It is the second most spread organic polymer on nature and found in vast lignocellulosic materials from agro and industrial wastes, therefore, hemicelluloses are considered as abundant and renewable raw material/feedstock. Biorefinery concept contributes to hemicelluloses production associated with biomass industrial processes. Hemicelluloses are alternative sources of sugars for renewable fuels and as platform for chemicals production. This book reviews chemical processes for sugar production and degradation, obtaining of intermediate and final products, and challenges for pentose fermentation. Aspects of hemicelluloses chain chemical and enzymatic modifications are presented with focus on physicochemical properties improvement for bioplastic and biomaterial approaches. Hemicelluloses are presented as sources for advanced materials in biomedical and pharmaceutical uses, and as hydrogel for chemical and medicine deliveries. An interdisciplinary approach is needed to cover all the processes involving hemicelluloses, its conversion into final and intermediate value-added compounds, and bioenergy production. Covering this context, this book is of interest to teachers, students, researchers, and scientists dedicated to biomass valorization. This book is a knowledge source of basic aspects to advanced processing and application for graduate students, particularly. Besides, the book serves as additional reading material for undergraduate students (from different courses) with a deep interest in biomass and waste conversion, valorization, and chemical products from hemicelluloses.

Nematodes continue to threaten horticultural crops throughout the world, particularly in tropical and sub-tropical regions. Estimated overall average annual yield loss of the world’s major horticultural crops due to damage by plant parasitic nematodes is 13.54%. Monetary losses due to nematodes on 10 horticultural crops, six of which are life sustaining were estimated at US $ 19.37 billion annually based on 1984 production figures and prices. The farmer in his anxiety to contain the nematode pest may resort to indiscriminate use of nematicides posing hazard to the environment. Since the horticultural produce especially fruits and vegetables are consumed afresh, consumers expect residue-free produce both for internal and export markets. In this context, developing ‘Integrated Nematode Management (INM)’ strategy is the challenge before the nematologists. The present book is an attempt which comprehensively deals with both principles and practices of INM. The first part deals with the principles of INM covering aspects such as introduction, role of nematodes in horticulture, interactions with other micro-organisms and nematode management options such as regulatory, physical, cultural, chemical, biological and integrated methods including host resistance. The second part deals with practices for nematode management in horticultural crops such as fruit, vegetable, ornamental, medicinal, aromatic, plantation, spice and tuber crops. This book is a practical guide to practicing farmers of horticultural crops. Further, it is a useful reference to policy makers, research and extension workers and students. The material can also be used for teaching undergraduate and post-graduate courses.

This book contains 22 chapters, 2 appendices (of the nematicides and species mentioned throughout the book) and 24 colour plates covering all aspects of practical plant nematology in subtropical and tropical agriculture, including rice, cereals, sweet potatoes, root and tuber crops, food legumes, vegetables, groundnut, citrus, tree and fruit crops, coconut and other palms, coffee, cocoa, tea, bananas, sugarcane, tobacco, pineapple, cotton, other tropical fibres, spices and medicinal plants. It provides practical guidance on the methods of extracting, processing and diagnosing different plant and soil nematodes and on integrated nematode management. This book is intended for those studying and working in the area of crop protection.

The second volume of the IMPD series describes aspects related to the most important phytoparasitic nematodes, considering the integration of biological control methods with other management practices and technologies, including the use of predatory nematodes and microbial rhizosphere antagonists. A focus is given on regional issues. A review on nematode management in cotton is integrated by a chapter on management of nematodes on wheat. New technologies are also revised.

This series originated during a visit of prof. K. G. Mukerji to the CNR Plant Protection Institute at Bari, Italy, in November 2005. Both editors convened to produce a series of five volumes focusing, in a multi-disciplinary approach, on recent advances and achievements in the practice of crop protection and integrated pest and disease management. This fourth Volume deals with management of nematodes parasitic of tree crops, and includes a section on tropical fruit crops and commodities, as well as a second section on tree crops from more temperate areas. The latter also includes a chapter updating the current knowledge about the pine wood nematode, Bursaphelenchus xylophilus. Volume 4 flanks Volume 2 of this IMPD series, which focused on management of vegetable and grain crops nematodes. Nematodes are a very successful, diversified and specialised animal group, present in nature in any ecological niche. Among nematode species, only a reduced number feeds on plants, of which a few species cause severe economic impacts on crop productions. Plant parasitic nematodes represent an important concern for a broad range of agricultural productions and systems, worldwide. This statement explains the attention devoted in last decades to nematodes, and the research and technical efforts invested for their control.

Nematodes are the most abundant and diversified group in the animal kingdom, with four out of five animals on earth being nematodes. Nematology was first recognised as an independent discipline during the early part of the century and since that time has made unparalleled advances to become an integral part of biological sciences.Written as two volumes, this title provides a broad overview of our current knowledge of nematology. The first volume addresses basic biology, while this second volume covers applied aspects of nematodes as parasites of plants, humans and other animals, or as disease vectors, and the control of pest nematodes. The contributors to this work include the world's leading authorities from Australia, Brazil, Canada, France, New Zealand, UK and USA. It will provide essential reading for researchers and students with an interest in nematology.
