What differentiates the two types of plant diseases?

The distinction between infectious and non-infectious diseases is crucial in understanding plant pathology. Infectious diseases are caused by pathogens such as fungi, bacteria, viruses, and nematodes that can spread from one plant to another, often impacting entire crops or ecosystems. These diseases can be transmitted through various means—such as air, water, soil, or through vectors—making them a key concern for growers aiming to maintain plant health.

In contrast, non-infectious diseases arise from environmental factors such as nutrient deficiencies, poor drainage, or extreme weather conditions. These do not involve pathogens and cannot be spread from plant to plant. Identification of the type of disease a plant is suffering from is essential for proper management—those affected by infectious diseases may require different control measures compared to those suffering from non-infectious issues.

The other options present different distinctions: transmissible and non-transmissible focus more on the transfer of disease rather than the nature of the pathogens; pathogenic and non-pathogenic emphasizes the presence or absence of disease-causing organisms; chronic and acute point towards the duration and speed of disease progression, rather than the underlying cause of the diseases themselves. Understanding these distinctions helps horticulturists manage plant health effectively by tailoring their approach based on the type
