Infectious causes are classified as biological (living) causes of plant problems. They include (but are not limited to) insects, mites and disease pathogens.Environmental stress, such as temperature damage and water or nutrient stress, is non-biological (Abiotic) factors that may affect plant health.

Are pathogens abiotic?

Abiotic diseases are just that: Diseases caused by abiotic factors. Technically, we could call these pathogens « pathogens », but most people reserve the term for the live pathogen of a disease. The term « pathogen » becomes less useful when abiotic diseases are caused by deficiencies, such as water or nutrient deficiencies.
