What is plant pathology and its importance?

Plant Pathology is the study of the diseases and disorders of plants. Disease can be defined as a harmful deviation from normal functioning of the physiological processes caused by an infectious agent. In the case of plant diseases, the causal agent maybe a fungus, virus, bacterium or a parasitic flowering plant.

What is the importance of plant pathology in agriculture?

Plant pathology can and should contribute in each of these respects–by assessing the immediate and potential dangers to crops from diseases, by forecasting their incidence and severity, by deploying the best methods of control in the short and longer term, by evaluating the risks particularly by integrated use of the …

What is the importance of plant pathogens?

Plant pathogens in the wild are potential sources of inoculum, of new biotypes, and of new diseases. Their importance to agriculture depends first on their host range and on the new biotypes they produce. It also depends on the feasibility of coping with these sources.

What does plant pathology means?

Plant Pathology is the study of plant diseases including:1) causes, 2) mechanisms by which diseases occur, 3) interactions between plants and disease-causing agents, and 4) controlling diseases.

Who is father of plant pathology?

Heinrich Anton de Bary (26 January 1831 – 19 January 1888) was a German surgeon, botanist, microbiologist, and mycologist (fungal systematics and physiology). He is considered a founding father of plant pathology (phytopathology) as well as the founder of modern mycology.

What is the importance of collection and preservation of plant diseases?

Preserved plant specimens provide us with important information about plant diversity and distribution, in a relatively permanent, and verifiable form that serves as evidence of a plant’s existence in time and space. If these specimens are properly preserved and maintained, they can last for well over 200 years.

What is the importance of proper plant disease diagnosis?

Without proper identification of the disease and the disease-causing agent, disease control measures can be a waste of time and money and can lead to further plant losses. Proper disease diagnosis is therefore vital. Often, plant pathologists have to rely on symptoms for the identification of a disease problem.

What is the ultimate objectives of plant pathology?

Scope and responsibilities of plant pathology is unlimited. Its ultimate goal is to prevent and control plant diseases of economic importance. Responsibilities of the science of plantpathology may be summarized as under. ✓ Study of etiology, symptoms, predisposing factors and recurrence of such diseases.

How does plant pathology work?

In their work, plant pathologists cooperate with plant breeders and crop management, insect, and weed specialists in developing integrated, environmentally sound approaches to managing crops and their pests. attack plants and to understand the effects of environmental conditions on disease development.

Who is Indian father of plant pathology?

What is the purpose of studying plant pathology?

It deals with the cause, ethology ( disease cycle) , resulting losses to plants and control of diseases. To study the causes of plant disease -living, non-living and environmental. To study the mechanism of disease development by pathogens. To study the interactions between pathogens and plant.

What is the pathophysiology of plant disease?

A plant disease cannot develop if a susceptible host, pathogen, and favorable environment do not occur simultaneously The major plant pathogens responsible for disease development in plants are fungi, bacteria, viruses, and nematodes The disease cycle describes the interaction of the pathogen with the host

Why do we need to study the pathogenesis of diseases?

To study the mechanism of disease development by pathogens. To study the interactions between pathogens and plant. To develop methods to control the disease to check the losses caused by the diseases. Thereby increasing productivity of the crops.

Why are plant fields so susceptible to disease?

The reason a field can be extremely affected by a disease is that all large cultures are made of clones, all the plants share the same genetic background, so if a pathogen adequately armed gets in the good field, it’s christmas.
