Fig 1.3 We also live with diseases that have been with us since the early days of horticulture in Australia.
Fig 1.4 Today's modern herbarium retains original specimens and uses
modern facelift packaging and state-of-the-art database technology.
Fig 1.6 Conventional research and modern molecular techniques allow
today's plant pathologists to develop recommendations for managing
plant pathogen outbreaks.
Fig 1.5 The economic and social effects of incursions of major plant
pathogens can be devastating, demonstrated by a recent outbreak
of citrus canker in Queensland (now eradicated).
This handbook is concerned with diseases caused by
pathogens. The major groups of plant pathogens are fungi,
bacteria, viruses and nematodes. All diseases caused by
pathogens are the result of an interaction between a
susceptible plant, a pathogen capable of causing disease
and a favourable environment.
Fig 1.7 Cooperative, international research is important for Australia's
farming future. It enables a better understanding of potential threats
to our horticulture.
The following sections outline the key characteristics
of plant pathogens.
