What are weeds ?How can we control them ?

Explanation

The undesirable plants in the field are called weeds which have to be removed, otherwise our own crop plants may not get sufficient water, nutrients, space and light. So, they are removed either by manual method or by using weedicides.
The manual removal includes physical removal of weeds by uprooting or cutting them close to the ground from time to time. This is done with the help of a khurpi or a harrow. By using weedicides also, we can remove weeds. These weedicides only damage weeds and do not harm crops.
