Organisms that cause infectious disease include fungi, oomycetes, bacteria, viruses, viroids, virus-like organisms, phytoplasmas, protozoa, nematodes and parasitic plants. Pscheidt, Extension Plant Pathology Specialist, OSU Adapted from L.W. ADVERTISEMENTS: List of ten major diseases caused due to bacteria in animals. They cannot spread from plant to plant, but are very common and should be considered when assessing the health of any plant. The word 'Phyto' refers to plant and pathogenic bacteria, fungi, molds and viruses specific to plant species are responsible for induction of disease symptoms. Symptoms may include a detectable change in color, shape or function of the plant as it responds to the pathogen. Plant pathogenic bacteria induce as many kinds of symptoms on the plants they infect as do fungi. To diagnose plant diseases effectively, it is necessary to understand the biology of the microorganisms that cause them: fungi, bacteria, and viruses. In infected seed, bacteria spread which propagates crop residues through rains that can be driven by wind or water splashes and various other sources. PLANT DISEASES Plant disease is an impairment of normal state of a plant that interrupts or modifies its vital functions. Vascular wilt results from the bacterial invasion of the plant’s vascular system. They constitute a very important factor limiting growth and cropping of cultivated plants. Bacteria in one plant can also spread to other plants, so often removal of an infected plant is necessary to contain the contagion. SIGNS, SYMPTOMS AND EFFECTS OF PLANT DISEASES PLANT DISEASES A plant disease is any abnormal condition that alters the appearance or function of a plant. Some of the same types of viruses that infect humans can also infect plants. Bumble Foot 9. Disease is caused by the bacterium entering the plant though stomata or wounds. The following table illustrates the major plant diseases caused by virus − There are different types of bacteria (good & bad), but in this article, we will explore a list of scary diseases caused by harmful bacteria. Examples of abiotic diseases include nutritional deficiencies, soil compaction, salt injury, ice, and sun scorch (Figure 61). They do great harm to many agricultural crops, especially cotton, tobacco, tomatoes, potatoes, cabbage, and cucumbers. The diseases are: 1. of soil change. They cause leaf spots and blights, soft rots of fruits, roots, and storage organs, wilts, overgrowths, scabs, and cankers (Fig. CAUSES OF PLANT DISEASES Plant diseases are caused by both infectious (fungi, bacteria, viruses and nematodes) and non infectious agents (mineral deficiency, sun burns etc). Figure 61. Plant pathology (also phytopathology) is the scientific study of diseases in plants caused by pathogens (infectious organisms) and environmental conditions (physiological factors). Diseases are the result of some disturbance in the normal life process of the plant. Many plant diseases are caused by pathogens ,disease causing agents are called pathogens. When people breathe in contaminated environment they often get affected by this disease. Diseases Caused by Pseudomonas syringae L.W. Some of the common plant pathogens are − Viruses. Fungi are minute organisms that live on plants and cause visible symptoms. It might be outdated or ideologically biased. GEORGE N. AGRIOS, in Plant Pathology (Fifth Edition), 2005.
