Which three components are necessary for a Biotic Disease to develop?

The development of a biotic disease is fundamentally reliant on three essential components: a pathogen, a susceptible host, and a favorable environment.

The pathogen is the organism responsible for causing the disease, which could be a virus, bacteria, fungus, or other disease-causing microbes. For the disease to manifest, there must be a susceptible host, meaning that the plant or organism must have certain weaknesses or vulnerabilities that allow the pathogen to invade and proliferate. Finally, the favorable environment is crucial as it provides the necessary conditions—such as appropriate temperature, moisture, and light—that enable the pathogen to thrive and infect the host.

Together, these three components create the perfect storm for a biotic disease outbreak, allowing it to spread rapidly and cause significant damage. Understanding this triad is vital for effective disease management and control strategies in agricultural practices.
