Phytopathology or Plant Pathology is the
science of diagnosing and managing plant
diseases. Its covers all infectious
agents that attack plants and abiotic disorders but does not include herbivory.
Common plant pathogens (in order of importance) include species from these groups:
- Fungi -- the most common pathogens (molds, rusts, and mildews).
- Bacteria -- prokaryotic
organsisms which include as many as 18 genera.
- Nematodes -- both as pathogens and vectors, the only animal plant
pathogens.
- Virus -- more than 700 are plant pathogens, comprised of only protein and DNA.
- Viroid -- small, single-stranded RNA pathogens causing a dozen plus diseases.
- Oomycetes -- commonly known as water molds, such as Phytophthora
infestans, potato blight.
- Myxomycetes -- slime molds, usually not actual pathogens but esthetically
unpleasant.
- Parasitic angiosperms -- plants that parasitize other plants, witchweed
and mistletoe are common examples.
