What is Phytopathological?
Plant pathology is the science that studies the causes of plant diseases, the mechanisms by which diseases develop in individual plants and in plant populations, and the ways and means by which plant diseases can be managed or controlled.
What is the scientific name of phytoplasma?

What are the parasitic agents of plant diseases?
Most plant diseases are caused by parasitic FUNGI, bacteria, mycoplasma, spiroplasma, viruses, viroids, nematodes and protozoa. In addition, some plants (eg, dodders, MISTLETOES) can parasitize other green plants.
What are signs of the pathogens?
Symptoms
- Fever.
- Diarrhea.
- Fatigue.
- Muscle aches.
- Coughing.
Who is the father of modern plant pathology?
Heinrich Anton de Bary (26 January 1831 – 19 January 1888) was a German surgeon, botanist, microbiologist, and mycologist (fungal systematics and physiology). He is considered a founding father of plant pathology (phytopathology) as well as the founder of modern mycology.
What are phytoplasma diseases?
Phytoplasmas are phloem-limited pleomorphic bacteria lacking the cell wall, mainly transmitted through leafhoppers but also by plant propagation materials and seeds. Phytoplasma diseases of vegetable crops are characterized by symptoms such as little leaves, phyllody, flower virescence, big buds, and witches’ brooms.
What is the importance of phytoplasma?
Phytoplasmas are pathogenic bacterial Mollicutes inhabiting the plant phloem. They are associated with severe plant diseases in many different species worldwide, with huge economic impacts on several important crops (Maejima et al.
What are the signs of plant disease?
A sign of plant disease is physical evidence of the pathogen. For example, fungal fruiting bodies are a sign of disease….Dark red kidney bean leaf showing bacterial leaf spot symptom (brown leaf spot with yellow halo). Photo credit: Fred Springborn, MSUE
- Mosaic leaf pattern.
- Crinkled leaves.
- Yellowed leaves.
- Plant stunting.
What is the most common cause of infectious plant diseases in ornamental plants?
Fungi usually produce spores which can cause infections when carried to a susceptible plant. Spores can be moved by wind, water, insects, and tools. Fungal spores require adequate moisture and the optimal air temperature in order to begin new infections. Many fungal diseases are common during wet, humid seasons.
How does the body get rid of pathogens?
The antibodies destroy the antigen (pathogen) which is then engulfed and digested by macrophages. White blood cells can also produce chemicals called antitoxins which destroy the toxins (poisons) some bacteria produce when they have invaded the body.
