Questions and Answers

Which of the following best defines plant disease?

  • Any malfunctioning of host cells and tissues that results from continuous irritation by a pathogenic agent or environmental factor and leads to development of symptoms. (correct)
  • Visible or invisible responses to a pathogen and/or an environmental factor.
  • A dynamic and continuous process that involves interactions among the host, pathogen, and environment over time.
  • A condition that occurs when a virulent pathogen, susceptible host, and favorable environment exist at the same time.
  • What is the disease triangle?

  • A diagram that represents the interactions among the host, pathogen, and environment in the development of plant disease. (correct)
  • A condition that occurs when a virulent pathogen, susceptible host, and favorable environment exist at the same time.
  • A concept that describes the visible or invisible responses of plants to a pathogen and/or an environmental factor.

    Study Notes

    Plant Disease and Management

    • Plant disease is best defined as the impairment of normal plant function, leading to adverse effects on plant growth, development, and productivity.

    The Disease Triangle

    • The disease triangle is a concept that describes the three essential components necessary for disease to occur: a susceptible host, a virulent pathogen, and a favorable environment.

    Key Requirement for Disease to Occur

    • The key requirement for disease to occur, according to the disease triangle, is the simultaneous presence of these three components.

    Integrative Disease Management

    • Integrative disease management involves the use of multiple approaches, including cultural, biological, genetic, and chemical controls, to manage plant diseases in a holistic and environmentally friendly manner.

    Exploiting the Disease Triangle in Management

    • The disease triangle can be exploited in the management of plant diseases by disrupting one or more of the three components, making it difficult for disease to occur.
    • This can be achieved through strategies such as crop rotation, sanitation, biological control, and resistant cultivars.
