Question: 1 / 400

What are the necessary components for the development of an infectious plant disease?

Favorable environment, Plant pathogen, Susceptible host, and Time

In order for an infectious plant disease to develop, all four components - a favorable environment, a plant pathogen, a susceptible host, and time - are necessary. Option B is incorrect because it includes a resistant host rather than a susceptible host. Option C is incorrect because it mentions host immunity rather than a susceptible host and suitable soil instead of a favorable environment. Option D is incorrect because it includes host resistance rather than a susceptible host and mentions suitable soil instead of a favorable environment. Therefore, option A is the best answer as it lists all the necessary components for the development of an infectious plant disease.
