Answer 1

Ques : What are weeds? How can we control them?

Soln: The unwanted plants that grow by their own in the cultivating fields and compete with required crops for food, light, space and essential nutrients present in the soil are called weeds. For example, Parthenium (gajar ghas), Cyperinus rotundus (motha).

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. Tilling before sowing of crops also helps in removing weeds: Tilling uproots the weeds.
