Question 9

What are weeds? How can we control them?

Answer

Weeds are the undesirable plants or we can say unwanted plants that may grow naturally along with the crops. They are hazardous to the crops as they compete with the crops for the food, nutrients, water and sunlight. Hence, they must be controlled.

The process of controlling or removing the weeds (unwanted plants) from the field is known as weeding. There are several methods to remove weeds such as tilling in which weeds are uprooted. They are removed manually by cutting with the help of Khurpi. They are also controlled by chemicals known as weedicides which kills the weeds.
