ONION MILDEW Meaning and
Definition
-
Onion mildew refers to a plant disease characterized by the growth of a fungal pathogen on the leaves and bulbs of onion plants. It is caused by various species of fungi, such as Peronospora destructor or Botrytis species, which thrive in humid and cool conditions. The primary symptom of onion mildew is the appearance of whitish-gray fungal growth on the leaves, stems, and bulbs of the affected plants.
This fungal growth often takes the form of fluffy or powdery patches and can be observed on both the upper and lower leaf surfaces. As the disease progresses, the patches may enlarge and merge together, covering large areas of the plant. Infected leaves may turn yellow or brown, wither, and eventually die. In severe cases, the pathogen may also attack the onion bulbs, causing them to rot.
Onion mildew can have detrimental effects on the growth and yield of onion crops. Infected plants may experience stunted growth, reduced bulb size, and decreased overall quality. Additionally, the disease weakens the plants, making them more susceptible to other pathogens and environmental stresses.
To prevent and manage onion mildew, practices such as crop rotation, proper spacing between plants, and removal of infected plant debris can be employed. Fungicides and biocontrol agents may be used as a means of controlling the disease, but prevention through good cultural practices is key. Regular scouting and early detection of symptoms are crucial for effective disease management.

Etymology of ONION MILDEW
The term "onion mildew" is a combination of two words: "onion" and "mildew".
1. Onion: The word "onion" comes from the Old English word "union" or "unyon", which was borrowed from the Latin word "unio". This Latin term referred to a large pearl, possibly due to the shape and appearance of an onion bulb. Over time, the word "onion" came to specifically represent the edible bulbous plant.
2. Mildew: The word "mildew" originated from the Old English word "meledēaw" or "meledeaw", which was a compound of "mele" (honey) and "dēaw" (dew). This Old English term referred to a sticky substance resembling honeydew that was found on plants, often caused by dampness or fungal growth.
