ABSTRACT
The most effective method to manage diseases is to exclude them from the field. Quarantine is important in preventing the spread of pathogens across countries, and legislative control is useful to prevent the entry of a pathogen into a new region. If a pathogen has entered into a region, eradication of the established infection is practiced. Because most diseases are spread internationally through seed, seed health testing and seed certification help to prevent the spread of diseases. Various seed health testing methods are described in this chapter.
