Solution(By Examveda Team)
Striga commonly known as witchweed is a genus of parasitic plants that occur naturally in parts of Africa, Asia, and Australia. Sorghum is the most common crop affected by striga.Cuscuta compestris is a parasitic plant that belongs to the family Convolvulaceae. It is a pest of Lucerne.
Typha is an aquatic or semi aquatic rhizomatous, herbaceous perennial herb plant. It is not a weed, it is a useful plant and source of fibre for rayon and crude. Thus its combination with sugarcane is wrong.
Orobanche is a flowering parasite on tobacco roots and occurs in all the tobacco tracts in India.
