Plant Virus and Viroid Diseases in the Tropics

Volume 2: Epidemiology and Management

• Broschiertes Buch

Produktbeschreibung

Around the globe, besides fungal and bacterial diseases, both virus and viroid diseases have acquired greater importance in the realm of plant pathology and call for effective management measures as they are responsible for heavy yield losses and are a matter of vital importance and concern to farmers, horticulturists, gardeners and foresters. Understanding disease epidemiology is of vital importance for formulating viable disease management practices in a given agro-ecosystem. The development and progress of plant disease epidemics are variable from region to region. Epidemiology is not a static process, but rather a dynamic course that varies with a change in the ecology, host, vector and virus systems.

Rezensionen

"The book provides an effective and comprehensive information on epidemiology and management aspects of virus and viroid diseases in tropics which is well written by the authors, regarding present status and possible feature strategies in holistic plant virus/vorid disease management. It should find a well-deserved place in the laboratories of different institutions and universities engaged in teaching and research in plant pathology and plant virology." (V. Muniyappa, Virus Disease, Vol. 27, 2016)

"This volume 1 will serve as one of the valuable and comprehensive reference book for the basic, practical and applied plant pathologists, scientists, teaching faculty and researchers of plant virology, plant pathology and plant biology. This volume is relevant and timely in view of the rapidly expanding international trade of plant and plant products. ... it is my pleasure to complement him, for his outstanding and comprehensive volume 1 on plant virus and viroid diseases in the tropics." (Teruo Sano, VirusDisease, Vol. 26, 2015)
