Book Description
The major objective of this book is to highlight the significance of phytonematodes in horticulture. Detailed and latest information on major aspects of phytonematodes associated exclusively with horticultural crops, which is the need of the day, is lacking. Hence, the book has been written mainly with the objective of providing its readers, comprehensive information on the advanced aspects related to phytonematodes associated with horticultural crops. It also provides basic information on plant parasitic nematodes since it is required for a better understanding of advanced topics. Several popular topics, information on which is already available in plenty, have been avoided. Thus, book explicates both the essential fundamental and advanced aspects pertaining to nematodes associated with horticultural crops. The book is conveniently divided into 13 chapters, which cover latest information on the major fundamental and advanced aspects related to phytonematodes including the role of phytonematodes in horticultural industry, phylogenetic and evolutionary concepts in nematodes, major phytonematodes associated with horticultural crops and their diagnostic keys, symptoms caused by phytonematodes and disease diagnosis, nematode population threshold levels, crop loss assessment, nematode diseases of horticultural crops and their management, nematode disease complexes, genetics of nematode parasitism, important nematological techniques and nematodes of quarantine importance. An exclusive chapter on novel methods of nematode management has been included mainly to provide the information on the latest molecules and novel modes of managing nematodes attacking horticultural crops. Routine nematode management aspects, information on which is already available, have not been discussed; instead, this topic reflects the changing scenario of future nematode management. Hence, this book can serve as a friendly guide to meet the requirements of the students, teachers and researchers interested in these ‘hidden enemies’ of the grower, apart from the research and extension personnel working under Public organizations, officials of State departments of Horticulture, Forestry, field workers and all those concerned and working with plant parasitic nematodes. Appropriate diagrams, convincing tables and suitable graphs/illustrations have been furnished at right places. A complete bibliography has also been included.

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.

Book Description
This book was first published in 1991 and was well received by students, teachers and researchers in many universities and institutes in India and abroad. In the past 28 years (since its first publication), tremendous progress have been made in temperate fruit research, notably in developing varieties and rootstocks, canopy management, understanding the flowering physiology, storage technology, biological control of pests and diseases, resistance breeding, biotechnology, etc., Revision of the book with updated information was considered necessary. In the process of a comprehensive literature survey it was felt impossible to compile all the information in one volume. This enlarged edition on temperate fruits is, therefore, published in tow volumes. The first volume consists of pome and stone fruits (apples, pears, peaches, plums, apricots and cherries) in more than 550 pages. The second volume deals with temperate nuts and berries (almonds, chestnuts, hazelnuts, pecans, pistachios, walnut, strawberries, currants, gooseberries, raspberries, blueberries and cranberries) in about 650 pages. Apart from through revision with updated scientific information on various aspects of mentioned pome, stone, nuts and berries, substantial reorganization of the text has been made. Emphasis has been laid to include released cultivars and rootstocks, recent trends in propagation and orchard management, pruning and canopy management, nutrition and tissue analysis, water management, improved technology for harvesting, postharvest handling, storage and ripening. Special emphasis has been laid to include the development in breeding and improvement through biotechnological approaches like molecular markers, genetic transformation, genetic map and microbes for N and P input. Other information like organic production technology, protected cultivation and impact of climate change are included, where sufficient information is available. Though the subject is vast, this two volumes book presents the concepts in a condensed, informative and lucid manner. It will be immense help to the students, teachers and researchers of horticulture, plant science, plant physiology and plant protection.

Book Description
This book illustrates the currently available strategies for managing phytonematodes. It discusses the latest findings on plant-pathogen-microbiome interactions and their impacts on ecosystems, and provides extensive information on the application of microorganisms in the sustainable management of phytonematodes. This is followed by an in-depth discussion of the application of potential strains of biocontrol fungi, endophytes and actinomycetes to enhance plants’ ability to fend off phytonematode attacks, leading to improved plant health. In conclusion, the book addresses new aspects like the biofabrication of nanoparticles and their application in plant disease management, and presents an extensive list for further reading.
