Abstract
Virus diseases are serious constraints to the productivity and profitability of a wide range of tropical crops. Identification of the causal viruses and understanding their epidemiology is the key to estimating the incidence and economic impact of the diseases they cause, and to devising virus management strategies. Epidemics result from interactions between virus, host plant, vector and environmental factors, and every epidemic can be considered to be a unique pathosystem in which each of the components contributes to the epidemic, and in which none are limiting. Pathogen diagnosis is the key to managing diseases, and we list 18 crops, their main virus/viroid diseases and pathosystem descriptors for each. Six types of pathosystem are described on the basis of the modeof spread,and the differentmanagementstrategies applicable to each are discussed. The Ninth Report of the International Committee on Taxonomy of Viruses (2012) is an essential reference for virologists working with tropical crops.
