5 Questions
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.
What is the disease triangle?
A diagram that represents the interactions among the host, pathogen, and environment in the development of plant disease.
What is the key requirement for disease to occur according to the disease triangle?
All of the above.
What is integrative disease management?
A management strategy that involves integrating multiple approaches to control plant diseases.
How can the disease triangle be exploited in the management of plant diseases?
By creating an unfavorable environment for pathogen growth.
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.
