What is Phytopathological?
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 are common methods to confirm their presence in host plants?
Laboratory-based techniques such as polymerase chain reaction (PCR), immunofluorescence (IF), fluorescence in-situ hybridization (FISH), enzyme-linked immunosorbent assay (ELISA), flow cytometry (FCM) and gas chromatography-mass spectrometry (GC-MS) are some of the direct detection methods.
What are basic methods used in management of plant pathogens?
Below are the basic principles of plant disease management.
- Exclusion. Exclusion of plant diseases consists of practices designed to keep pathogens (things that cause disease), vectors (things that spread disease) and infected plants out of disease-free areas.
- Eradication.
- Protection.
- Resistance.
- Therapy.
Why is plant pathology is important?
Continuing advances in the science of plant pathology are needed to improve disease control, and to keep up with changes in disease pressure caused by the ongoing evolution and movement of plant pathogens and by changes in agricultural practices. Plant diseases cause major economic losses for farmers worldwide.

What is the study of Phytopathology?
Phytopathology or plant pathology is the science of diagnosing and managing plant diseases. It covers all infectious agents that attack plants and abiotic disorders, but does not include herbivory by insects, mammals, etc. Approximately ten percent of food production is lost to disease worldwide.
How do you manage plant viruses?
The approaches are mainly based on avoidance of sources of infection; avoidance or control of vectors; modification of cultural practices; use of resistant varieties obtained though conventional breeding procedures; cross protection; systemic acquired resistance; and use of transgenic plants containing alien genes that …
How can plant viruses be controlled?
Plant viruses need to be transmitted by an organism-vector (insects, nematodes, zoosporic endoparasites) for their plant-to-plant spread. Hence, viral diseases can be efficiently controlled by limiting the populations of their vectors with the applications of appropriate pesticides.
What are the main principles of plant disease control?
The six fundamental principles of disease management are exclusion, eradication, protection, resistance, therapy, and avoidance of insect vectors and weed hosts.
What is the best principle and method of plant disease control?
Traditional Principles of Plant Disease Control. Avoidance—prevent disease by selecting a time of the year or a site where there is no inoculum or where the environment is not favorable for infection. Exclusion—prevent the introduction of inoculum. Eradication—eliminate, destroy, or inactivate the inoculum.
Who is the father of 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.
