Answer 1

Answer:

The unwanted plants that grow along and compete with the crops are called Weeds. They compete for nutrients and water with the main crop. Some weeds interfere even in harvesting and may be poisonous for animals and human beings. Therefore, they are very harmful. 

The process of controlling the weed is called Weeding. Weeding is done manually by using a khurpi and by using mechanical machines. Weeds can also be controlled using chemicals like 2,4—D. These chemicals are called weedicide and are used to kill and destroy the weeds.
