Generally, Orobanche weed is found in
Discuss
Answer & Solution
Answer: Option A
Solution:
Orobanche, commonly known as broomrape, is a parasitic weed that lacks chlorophyll and depends entirely on its host plant for water and nutrients.

This weed is commonly found in tobacco fields, where it attaches itself to the roots of tobacco plants and derives nourishment from them. Heavy infestation of Orobanche can significantly reduce crop yield and quality.

Orobanche is considered a major agricultural pest because it weakens the host plant by drawing essential nutrients, thereby affecting plant growth and productivity.

The development of genetically modified (GM) tobacco plants resistant to Orobanche has been one of the applications of biotechnology in crop protection.

Option B (Gram field), Option C (Rice field), and Option D (Wheat field) are incorrect because Orobanche is most commonly associated with infestations in tobacco and certain other broadleaf crops, not rice or wheat fields.

Therefore, Option A (Tobacco field) is the correct answer.
