LONG-DISTANCE DISPERSION OF RUST PATHOGENS

Describes some of the evidence and routes by which long-distance dispersal (LDD) of plant pathogens is known to occur in various parts of the world. The chapter also contains a description of new tools by which LDD can be studied and made into a predictive tool for advisory services. When pathogen propagules spread to locations >1000 km away to cause fresh infections in the target area, such a dispersal is called LDD. The different phases of LDD (take-off, dispersal, deposition) are influenced by micro and macro weather conditions. -from Authors
