What are the 3 types of microorganisms that cause plant disease?
Infectious plant diseases are mainly caused by pathogenic organisms such as fungi, bacteria, viruses, protozoa, as well as insects and parasitic plants [1].
What are the common plant diseases caused by microorganisms?
Diseases caused by Microorganisms in Plants
| Disease Name | Microorganism | Transmitted by |
|---|---|---|
| Citrus Canker | Bacteria | Air |
| Rust of Wheat | Fungi | Air, seeds |
| Yellow vein mosaic of Ladyfinger (Okra/Bhindi) | Virus | Insects |
What are plant pathogenic bacteria?
Plant pathogenic bacteria induce as many kinds of symptoms on the plants they infect as do fungi. They cause leaf spots and blights, soft rots of fruits, roots, and storage organs, wilts, overgrowths, scabs, and cankers (Fig. 12-4).
What are examples of plant bacteria?
Most plant pathogenic bacteria belong to the following genera: Erwinia, Pectobacterium, Pantoea, Agrobacterium, Pseudomonas, Ralstonia, Burkholderia, Acidovorax, Xanthomonas, Clavibacter, Streptomyces, Xylella, Spiroplasma, and Phytoplasma.
What are plant diseases?
Plant disease is defined as the state of local or systemic abnormal physiological functioning of a plant, resulting from the continuous, prolonged ‘irritation’ caused by phytopathogenic organisms (infectious or biotic disease agents).

How to control bacterial diseases in plants?
Bacterial diseases in plants are difficult to control. Emphasis is on preventing the spread of the bacteria rather than on curing the plant. Integrated management measures for bacterial plant pathogens include: 1. Genetic Host Resistance Resistant varieties, cultivars or hybrids is the most important control procedure. 2. Cultural Practices
What are plant pathogens and how do they affect plants?
Plant pathogens are very similar to those that cause disease in humans and animals. Fungi, fungal-like organisms, bacteria, phytoplasmas, viruses, viroids, nematodes and parasitic higher plants are all plant pathogens. Fungi and Fungal-like Organisms (FLOs)
What is the most common pathogenic bacteria in plants?
The most commonly found pathogenic bacteria are bacilli (rod-shaped). These bacteria act on different parts of the plants, and localize and inhibit few functions of the plants. Some are cell wall–degrading bacteria species such as Erwinia.
