Answer:
In a field many other undesirable plants may grow naturally along with the crop. These undesirable plants are called weeds. Weeds can be controlled by methods called weeding. Tilling before sowing of crops helps in uprooting and killing of weeds, which may then dry up and get mixed with the soil. Weeds are also controlled by using certain chemicals, called weedicides.

Answer:
Weeds are unwanted plants that grow along with crops and fight with them for water, sunlight and nutrients. We can control them by spraying weedicides like dalapon, metachlor and siniazine. They can also be controlled by manual methods in which they are uprooted either by hand or by using a harrow or trowel(khurpa).
