Epidemiology of sharka disease in North America

Authors


Abstract

The history of North American (USA and Canada) epidemics of Plum pox virus (PPV), as well as hypotheses about the general North American epidemiology of PPV, are summarized. The hierarchical sampling method, combined with reliable DASI-ELISA detection/confirmation procedures, were successfully used for extensive PPV surveys of stonefruit-producing areas in both countries. The influence of epidemiological analyses on eradication policy is described.
