Bacterial Pathogens
They are saprotrophic and do not harm the plant itself. Bacteria are responsible for several plant diseases in subtropical and tropical regions because of temperature requirements. Bacilli are main bacterial pathogens because they secrete several effector proteins to initiate the disease, which include CWDE, toxins, phytohormones, and Exopolysaccharides (EPS).
Examples of Bacterial Agents
Some examples of bacterial agents are :
- Erwinia spp. – Causes Soft rot by secreting CWDE
- Agrobacterium spp. – Causes tumours
- Pseudomonas syringae – Inhibits tomato fruit productivity
Plant Pathology
Plant pathology is the study of illnesses brought on by plant pathogens, also called phytopathogens. Nematodes, bacteria, fungi, viruses, and protozoa are some of these pathogens. Phytopathologists are scientists who study plant pathology. Plant diseases can be caused by various pathogens, including both prokaryotic and eukaryotic organisms.
In this article, we will study the Definition and Principles of Plant Pathology, Types of plant pathogens, Fungal pathogens, Bacterial pathogens, Viral Pathogens, nematode pathogens, protozoa, and algae pathogens, Epidemiology of plant diseases, Prevention and Control of Protozoan Diseases and Importance of Plant Pathology.
