LATE BLIGHT Meaning and
Definition
-
Late blight is a devastating and highly destructive plant disease caused by the fungal-like pathogen Phytophthora infestans. It primarily affects plants of the Solanaceae family, mainly tomatoes and potatoes. Late blight is characterized by rapidly spreading lesions that usually appear on the leaves, stems, and fruits of affected plants. These lesions typically have dark, water-soaked spots that can quickly turn brown or purplish-black, resulting in tissue death.
Late blight thrives in cool, wet environments, making it a significant concern for farmers, gardeners, and horticulturists. It can lead to mass crop failures and significant economic losses. The disease can spread rapidly through wind-borne spores, rain splash, and infected plant debris, making it highly contagious and difficult to control.
The fungus-like pathogen responsible for late blight thrives in temperatures ranging from 10 to 25 degrees Celsius and is favored by high humidity. Under optimal conditions, the disease can develop and spread within a matter of days, decimating entire fields if left unchecked.
Early detection and management practices such as regular scouting, proper sanitation, and the use of resistant varieties are crucial in preventing the spread of late blight. Chemical control methods, including the use of fungicides, can also be employed, but integrated pest management strategies are often recommended to reduce reliance on chemical treatments and minimize environmental impact.
Due to its historical significance, late blight holds a notable place in agricultural history, as it played a pivotal role in causing the Irish Potato Famine in the 19th century, which led to widespread starvation and emigration.

Etymology of LATE BLIGHT
The word "late blight" is derived from the combination of "late" and "blight".
"Late" comes from the Old English word "lǣt", meaning "slow", "sluggish", or "belated". In this context, it refers to the fact that the disease typically affects plants in the later stages of their growth cycle.
"Blight" originates from the Old English word "blēaht", which referred to a condition that caused decay or destruction. It is related to the Proto-Germanic word "blīhtiz", meaning "to strike" or "to beat".
So, when combined, "late blight" describes a disease that strikes plants later in their growth cycle and leads to their decay or destruction.
