Abstract:
"This book aims to provide readers with the latest information on important virus diseases of crops in tropical and subtropical countries and the envisaged directions into the future of plant virus control. The volume comprises 18 chapters. The first chapter covers general information on the impact of virus diseases, methods for estimating disease severity, recent data on host-virus interactions, serological and molecular techniques for the diagnosis of virus pathogens, and disease management strategies. Subsequent chapters examine selected virus diseases, inclusive of the hosts, vectors and viruses and their intricate relationships, symptoms development, virus transmission, host resistance and the underlying biochemical and genetic factors leading to disease, as well as their control using a variety of techniques including genetic modification. The structure of the various virus epidemics covered in this book is different and complex, dependent on the nature of the virus or viruses, their relationship with their vectors, geographical location, among other factors such as political and social approaches that deal with food security. Much progress has been achieved, but there is much work remaining on the pursuit and development of knowledge-based disease management strategies, regulatory policies and synergies between all the stakeholders."
