Book Description
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.

Book Description
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.

Book Description
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.

Book Description
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. These deleterious effects on plant growth result in reduced yields and poor quality of horticultural crops. Nematode management is therefore, important for high yields and quality that are required by the high cost of modern crop production. The information on nematode diseases and their management, especially crop wise, is very much scattered and there is no book which deals entirely with the above aspects on horticultural crops. This book deals with nematode diseases and their management in horticultural crops such as fruit, vegetable, orname-ntal, medicinal, aromatic, plantation, spice and tuber crops. Each nematode disease is described in adequate detail under the following heads: economic importance, crop losses, distribution, symptoms, hosts range, life cycle, races/ biotypes, host-parasite relationship, histopathology, ecology, spread, survival, interaction with other pathogens and management. The management methods presented includes regulatory, physical cultural, chemical, biological, host resistance and integrated approach. An entire chapter is devoted for sources of availability of critical inputs used for nematode management which would be very useful to the farmers. Very useful information on certain aspects of nematode management is presented in Appendix. The book is adequately illustrated with about 50 figures. 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 under-graduate and post-graduate courses.
