What are the different types of plant diseases?
Plant disease, an impairment of the normal state of a plant that interrrupts or modifies its vital functions. Plant diseases can be classified as infectious or noninfectious, depending on the causative agent. Learn more about the importance, transmission, diagnosis, and control of plant diseases.
Why are cultivated plants more susceptible to disease?
Cultivated plants are often more susceptible to disease than are their wild relatives. This is because large numbers of the same species or variety, having a uniform genetic background, are grown close together, sometimes over many thousands of square kilometres.
What are the causes of noninfectious plant disease?
Definitions of plant disease. Noninfectious plant diseases are caused by unfavourable growing conditions, including extremes of temperature, disadvantageous relationships between moisture and oxygen, toxic substances in the soil or atmosphere, and an excess or deficiency of an essential mineral.
Which is the primary causal agent of plant disease?
Plant diseases can be broadly classified according to the nature of their primary causal agent, either infectious or noninfectious. Infectious plant diseases are caused by a pathogenic organism such as a fungus, bacterium, mycoplasma, virus, viroid, nematode, or parasitic flowering plant.
