Diseases caused by pathogens
A pathogen is a living organism or virus directly capable of causing disease. The term “disease” is defined as a harmful deviation from the normal functioning of physiological processes. Many taxonomically diverse organisms become phytopathogenic (cause plant diseases) under suitable conditions. Plant pathogens can be categorized by their formal biological classification (taxonomy).
