Question

During crop cultivation, Rahul observed that plant ​X was growing along with crops. He sprayed a ​chemical Y to remove this plant. Identify X and Y.

• A. X is a cash crop, Y is ​
  an insecticide​
• B. X is a weed, Y is a weedicide​
• C. X is a fodder crop, ​
  Y is a herbicide​
• D. X is a weed, Y is a fertiliser​

Answer 1

The correct option is B X is a weed, Y is a weedicide​

• The undesirable plants that grow along with the crops are called weeds. These weeds feed on the nutrients provided to the crops and thus reduce the supply of nutrients to the crops, thereby hindering their growth.
• Weeds can be controlled using weedicides. It is a chemical, which is sprayed in the fields to kill all available weeds. Weedicides are not harmful to crops.
• Hence, X is a weed and Y is a weedicide.
