PLANT DISEASE Meaning and
Definition
-
Plant disease refers to the impairment of a plant's physiological functions caused by various pathological agents, leading to a deviation from its normal growth, development, and appearance. It is a broad term encompassing all infectious and non-infectious disorders that negatively impact plant health and reduce productivity.
Infectious plant diseases are caused by living organisms, including fungi, bacteria, viruses, and other pathogens. These pathogens invade the plant, multiplying and colonizing various tissues, disrupting vital processes such as photosynthesis, nutrient uptake, and water transport. Common examples of infectious plant diseases include powdery mildew, bacterial blight, and viral mosaic.
Non-infectious plant diseases, also known as abiotic diseases, are caused by environmental factors rather than living organisms. These can include nutrient deficiencies or imbalances, extreme temperatures, excessive or insufficient moisture, pollutants, or physical injuries. Non-infectious diseases affect plants directly without any involvement of pathogens. Examples include symptoms like leaf chlorosis, wilting, and necrosis.
Plant diseases can significantly impact agricultural productivity and cause economic losses. They can affect crops, garden plants, ornamental flowers, and trees, depending on the specific host range of the pathogen. Plant pathologists study plant diseases to understand their causes, symptoms, and evolutionary relationships. This knowledge helps in developing management strategies such as cultural practices, genetic resistance, and chemical control to minimize the impact of diseases on plants and ensure sustainable agriculture.

Etymology of PLANT DISEASE
The word "plant disease" is derived from the combination of the words "plant" and "disease".
The term "plant" comes from the Old English word "plante", which originated from the Latin word "planta" meaning "seedling" or "sprout". This Latin word itself has Indo-European roots and relates to the verb "plantare", meaning "to plant".
The word "disease" has a different etymology. It can be traced to the Old French term "desaise", which was derived from the Latin word "dis-" (meaning "apart" or "away") and "aidein" (meaning "to speak"). Therefore, "disease" initially referred to the idea of disordered or disturbed physiological functioning.
When combined, "plant disease" refers to any abnormal condition that affects plants, obstructing their normal growth or functioning.
