What is simple interest Disease?

Simple interest, or monocyclic diseases, were ones that increased mathematically — similar to simple interest on money. Monocyclic diseases develop one generation of infection and rarely does secondary infection occur during the season.

What is Polyetic disease?

Epidemics that occur under these conditions are referred to as polyetic epidemics and can be caused by both monocyclic and polycyclic pathogens. Apple powdery mildew is an example of a polyetic epidemic caused by a polycyclic pathogen and Dutch Elm disease a polyetic epidemic caused by a monocyclic pathogen.

What is Epiphytotic disease?

When the number of individuals a disease affects increases dramatically, it is said to have become epidemic (meaning “on or among people”). A more precise term when speaking of plants, however, is epiphytotic (“on plants”); for animals, the corresponding term is epizootic.

What are the plant disease classifications?

According to this criterion, plant diseases are classified into two types: infectious (biotic) diseases, which are caused by eukaryotes, prokaryotes, parasitic higher plants, viruses/viroids, nematodes, and protozoa, and noninfectious (abiotic) diseases, which are caused by different extreme environmental conditions [5 ...

What is disease triangle?

The disease triangle is a conceptual model that shows the interactions between the environment, the host and an infectious (or abiotic) agent. This model can be used to predict epidemiological outcomes in plant health and public health, both in local and global communities.

What is disease cycle?

Abstract. AbstractPlant disease cycles represent pathogen biology as a series of interconnected stages of development including dormancy, reproduction, dispersal, and pathogenesis. The progression through these stages is determined by a continuous sequence of interactions among host, pathogen, and environment.

What are the 5 stages of disease?

The five periods of disease (sometimes referred to as stages or phases) include the incubation, prodromal, illness, decline, and convalescence periods (Figure 2).

What are the types of disease cycle?

There are two types of disease cycles, monocyclic and polycyclic.

How do you control plant diseases?

When choosing varieties, select those that have a genetic resistance to common diseases. Provide plants with proper nutrients.
...
The following are some precautions you can take to have healthy plants.

  1. Provide plants with adequate space. ...
  2. Use good sanitation. ...
  3. Control weeds and insect pests.

What are the six steps involved in the disease cycle?

The virus life cycle could be divided into six steps: attachment, penetration, uncoating, gene expression and replication, assembly, and release.

What is sporadic disease example?

Patterns of Incidence. Diseases that are seen only occasionally, and usually without geographic concentration, are called sporadic diseases. Examples of sporadic diseases include tetanus, rabies, and plague.

What are the causes of plant diseases?

Most plant diseases – around 85 percent – are caused by fungal or fungal-like organisms. However, other serious diseases of food and feed crops are caused by viral and bacterial organisms. Certain nematodes also cause plant disease.
