What are weeds? How can we control them?

The undesirable plants may grow naturally along with the crops. These are called weeds. There are many ways to remove weeds and control their growth. Weeds can be removed by uprooting or cutting them close to the ground, from time to time. This is done with the help of a khurpi. Weeds are also controlled by using certain chemicals, called weedicides. These are sprayed in the fields to kill the weeds.
