Answer
Weeds are undesirable plants that grow along with the main crop. Weeds can be controlled by following methods:
- Tilling before sowing of crops helps in uprooting and killing of weeds
- Weeds can be manually removed with the help of khurpi by uprooting or cutting them close to the ground.
- Weeds should be removed before their flowering because they produce seeds in large number which are easily dispersed by wind.
- Weeds are also controlled by using certain chemicals, called weedicides, like 2,4-D. These are sprayed in the fields to kill the weeds. They do not damage the crops.
