What is the concept of 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).

What is plant disease management?

In agriculture, disease management is the practice of minimising disease in crops to increase quantity or quality of harvest yield. Organisms that cause infectious disease in crops include fungi, oomycetes, bacteria, viruses, viroids, virus-like organisms, phytoplasmas, protozoa, nematodes and parasitic plants.

What are the different methods of plant disease management?

A variety of chemicals are available that have been designed to control plant diseases by inhibiting the growth of or by killing the disease-causing pathogens. Chemicals used to control bacteria (bactericides), fungi (fungicides), and nematodes (nematicides) may be applied to seeds, foliage, flowers, fruit, or soil.

What is the best principle and method of plant disease control Why?

Traditional Principles of Plant Disease Control. Avoidance—prevent disease by selecting a time of the year or a site where there is no inoculum or where the environment is not favorable for infection. Exclusion—prevent the introduction of inoculum. Eradication—eliminate, destroy, or inactivate the inoculum.

What are the 10 principles of plant pathology?

For ornamental plants the Plant Pathologist must first examine such abiotic diseases as: 1) high or low temperatures, 2) excess or deficiency of water, 3) excess or deficiency of light, 4) lack of oxygen, 5) air pollution, 6) nutrient deficiencies, 7) mineral toxicities, 8) soil alkalinity or acidity, 9) toxicity of …

What are disease management tools?

Disease management programs (DMPs) are structured treatment plans that aim to help people better manage their chronic disease and to maintain and improve quality of life. DMPs are also run with the general goal of improving medical treatment in the long term. They are also called “structured treatment programs.”

What is disease management control?

Disease management is defined as “a system of coordinated healthcare interventions and communications for populations with conditions in which patient self-care efforts are significant.”

What are the three basic goals of plant maintenance?

To maximize the availability of plant, equipment and machinery for productivity through planned maintenance. To extend the life span of the plant, equipment , machinery etc., by minimizing their wear and tear and deterioration. To reduce the cost of production due to plant breakdown due to improper plant maintenance.

What are the two principles of plant disease prevention?

The first principle (prevention) includes disease management tactics applied before infection (i.e., the plant is protected from disease), the second principle (therapy or curative action) functions with any measure applied after the plant is infected (i.e., the plant is treated for the disease).

How have we improved our understanding of plant diseases?

Following our discovery of the causes of plant diseases in the early nineteenth century, our growing understanding of the interactions of pathogen and host has enabled us to develop a wide array of measures for the control of specific plant diseases.

What is Maloy’s Plant Disease Control principle?

These and other disease control principles are discussed in Maloy, Plant Disease Control (1993) cited in the general references of this lesson. This principle is defined as any measure that prevents the introduction of a disease-causing agent (pathogen) into a region, farm, or planting.

Where can I find information about plant disease management procedures?

Management procedures for some specific crops and diseases can be found in the APSnet Education Center online plant disease lessons. Plant disease management practices rely on anticipating occurrence of disease and attacking vulnerable points in the disease cycle (i.e., weak links in the infection chain).
