What is the primary difference between infectious and non-infectious plant diseases?
What is the primary difference between infectious and non-infectious plant diseases?
- Infectious diseases are virulent; non-infectious are benign.
- Infectious diseases cannot affect plants; non-infectious can.

Plant disease cause
Plant disease cause
Caused by either a pathogen (biotic) or environmental factor (abiotic).
Infectious plant disease
Infectious plant disease
Caused by a living thing (pathogen) that can reproduce and spread.
Non-infectious plant disease
Non-infectious plant disease
Caused by unfavorable growing conditions, not living organisms.

Study Notes
Plant Disease Classification
- Plant diseases are categorized as biotic (infectious) or abiotic (non-infectious).
- Biotic diseases are caused by pathogens, living organisms capable of infecting and replicating within the plant.
- Abiotic diseases result from environmental factors like soil or atmospheric conditions, or nutrient imbalances.
Biotic Plant Diseases
- Caused by specific pathogenic organisms such as fungi, bacteria, mycoplasmas, viruses, viroids, nematodes, or parasitic plants.
- Pathogens reproduce within or on the host plant.
- Pathogens can spread readily from one plant to another.
Abiotic Plant Diseases
- Caused by unfavourable growing conditions, such as soil or atmospheric conditions, and mineral deficiencies or excesses.
- Non-infectious factors are not organisms and, therefore, cannot be transmitted.
Plant Pathology
- The study of plant diseases is called plant pathology.
