GLUME BLOTCH Meaning and
Definition
-
Glume blotch is a term used in the field of plant pathology to describe a specific type of fungal disease that affects the glume of a cereal grain plant. Cereal grains include crops such as wheat, barley, rice, and corn, among others.
The glume is a protective outer casing or covering that surrounds the actual grain or seed of the cereal plant. It serves to shield the grain from environmental factors and potential pathogens. However, glume blotch is caused by fungal pathogens, typically belonging to the genus Stagonospora or Septoria, which infect and damage the glume.
Symptoms of glume blotch typically appear as irregular, dark brown to black discoloration or lesions on the surface of the glume. These lesions can vary in size and shape and may expand to cover a significant portion of the glume. In severe cases, the lesions can coalesce, leading to the browning and necrosis of large areas of the glume.
Glume blotch can reduce grain quality and yield, as it can affect the normal development and maturation of the cereal grain. The fungal pathogens responsible for glume blotch can survive on crop residues or in the soil, potentially leading to recurring infections in subsequent plantings.
Management of glume blotch typically involves a combination of cultural, biological, and chemical control methods. These may include practices such as crop rotation, removal of infected residues, use of disease-resistant varieties, and application of fungicides at appropriate timings.
Overall, glume blotch is an important disease to be aware of in cereal grain production, as it can have significant economic implications for growers and impact food production.

Etymology of GLUME BLOTCH
The word "glume blotch" consists of two distinct terms: "glume" and "blotch".
1. Glume:
The term "glume" originates from the Latin word "gluma", which means husk or chaff. In botany, a glume refers to a bract or scale-like structure that surrounds or protects the florets in grasses and some other plants. This protective structure is usually found at the base of the spikelet, a unit of inflorescence.
2. Blotch:
The word "blotch" comes from the Middle English word "blotche", which means a large discoloration or stain. It can be traced back to the Old Norse word "bӯtla" (meaning a scar) and the Old English word "blōstma" (meaning a skin eruption or inflamed swelling).
