Plant disease, an impairment of the normal state of a plant that interrrupts or modifies its vital functions. Plant diseases can be classified as infectious or noninfectious, depending on the causative agent. Learn more about the importance, transmission, diagnosis, and control of plant diseases. Soil microorganisms are key players in determining the plant growth and crop productivity worldwide. Among different microorganisms, members of the genus Streptomyces are one of the major microorganisms which are either responsible for plant diseases suppression and growth regulation. In some cases, they are also reported for plant diseases. Plant Diseases History of plant pathology  Causes of plant disease  Bacteria  Fungi  Viruses and viroids  Nematodes  Other causes of plant diseases  Disease cycles  Control  Resources  Like human beings and other animals, plants are subject to diseases. Plant pathogenic bacteria cause many serious diseases of plants throughout the world (Vidhyasekaran ; Figure 2), but fewer than fungi or viruses, and they cause relatively less damage and economic cost (Kennedy and Alcorn ).Most plants, both economic and wild, have innate immunity or resistance to many pathogens.
Diagnostic tests for identification of biotic causal agents. A major problem in identification of biotic causal agents is the inability of some infectious pathogens to grow on artificial media. Viruses, as well as some fungi (e.g. powdery and downy mildew causing agents) and some prokaryotes (e.g. phytoplasmas), require a living host in order. Plant disease epidemiology is the study of disease in plant populations. Much like diseases of humans and other animals, plant diseases occur due to pathogens such as bacteria, viruses, fungi, oomycetes, nematodes, phytoplasmas, protozoa, and parasitic plants. Plant disease epidemiologists strive for an understanding of the cause and effects of disease and develop strategies /5(79). How to Dispose of a Diseased Plant. Many plant diseases can quickly return if the dead plant matter isn’t properly disposed of. In fact, most fungal, bacterial and viral plant diseases are spread naturally by wind currents, rain, soil seeds, insects and other animals. Others can survive on nearby dead plants or infected gardening tools. So, there is a need to integrate understanding of bacterial taxonomy, genomics, and basic plant pathology that reflects state-of-the-art knowledge about plant-disease mechanisms. This book describes seventy specific bacterial plant diseases and presents up-to-date classification of plant pathogenic : BS Thind.
Guidelines for Identification and Management of Plant Disease Problems: Part II. Diagnosing Plant Diseases Caused by Fungi, Bacteria and Viruses1 Ken Pernezny, Monica Elliott, Aaron Palmateer, and Nikol Havranek2 1. This document is PP, one of a series of the Plant Pathology Department, UF/IFAS Extension. Original publication date February Plant Diseases in History Description. Learn about how plant diseases have impacted human history and how plant diseases continue to be important in our daily lives and in pop culture. Preview Available formats.

This book discusses the latest information on the epidemiology and management of phytoplasma-associated diseases, providing a comprehensive, up-to-date overview of distribution, occurrence and identification of the phytoplasmas, recent diagnostics approaches, transmission, losses and geographical distribution as well as management aspects. Biological control using fungal and bacterial antagonists to manage plant diseases seems to be a promising alternative strategy and have successfully been applied to control some diseases on different plants and crops. Biocontrol strategies may also be used to .
