What is a plant disease called?
The science of plant diseases is called plant pathology, or phytopathology. There are a wide variety of microorganisms such as fungi, bacteria, viruses and nematodes that cause these diseases. Diseases caused by these pathogens are often called biotic diseases. A plant disease is any abnormal condition that alters the appearance or function of a plant. It is a physiological process that affects some or all plant functions. Disease may also reduce yield and quality of the harvested product. Disease is a process or a change that occurs over time.A plant disease is defined as abnormal growth of the plant, or interference with the normal function of the plant.Plant pathology is the study of the organisms and of the environmental factors that cause disease in plants; of the mechanisms by which these factors induce disease in plants; and of the methods of preventing or controlling disease and reducing the damage it causes.In subject area: Agricultural and Biological Sciences. Viral diseases in plants refer to illnesses caused by plant-infecting viruses that damage crop yield and quality, posing significant threats to global food security.
What is plant leaf disease?
Most leaf spot diseases are caused by fungi, but a few diseases are caused by bacteria or other pathogens. Many pathogens are somewhat host-specific and will only cause disease on trees in the same family. Almost all trees and shrubs are susceptible to one or more leaf spot diseases. The correct answer is Chondrostereum purpureum. Chondrostereum purpureum is a fungal pathogen known to cause Silver Leaf disease in plants, particularly affecting species such as fruit trees and ornamentals. It was recently reported to cause infection in humans, making it a zoonotic pathogen.
What are the three types of plant diseases?
Plant infections are caused by pathogens. Pathogens are agents that cause disease and include fungus, bacteria, and viruses. Plant diseases can be identified according to the effect the pathogen has on the plant. Common plant diseases can be divided into these three categories: fungal, bacterial, and viral. Fungi and Fungal-Like Organisms: Collectively, fungi and fungal-like organisms (FLOs) cause more plant diseases than any other group of plant pathogens.
