Welcome to the Plants, Pathogens, and People Podcasts! Each weekly podcast will review a major concept or issue that will be discussed in class, will clarify a possible point of confusion, and will provide study hints that may be useful as you study for quizzes and the final exam.

The Major Concept for this week is the plant disease triangle. The plant disease triangle is a diagrammatic representation of the three fundamental elements required for disease: a susceptible plant, a pathogen capable of causing disease, and a favorable environment. If any of these three elements is missing, no disease occurs.

This Week's Point of Confusion is the difference between the terms pathogen and disease. It is important to differentiate between a pathogen and a disease and NOT to use these two terms as synonyms. PODCAST: pppodcastweek1.mp3
