What is weeding and what are the different methods of weeding?

Weed:

The unwanted plants that grow in the crop fields and extract nutrition from the soil and thus reduce the nutrient supply of our planned crops are known as weeds.

Weeding:

It is the process of removal of the weeds from the crop fields either manually or using chemicals.

It can be done by a few methods which are mentioned as follows:

(a) Manual: In this method, the weed is uprooted from the soil by hands in the crop fields and then burnt.

(b) Weedicide:

1. These are inorganic chemicals that are sprayed in the crop fields and kill those weed plants.
2. These work very specifically and thus do not harm the crops we have planted in the field and selectively kill the weed.
3. Very common examples of weedicide are 2,4- Dichlorophenoxy acetic acid, Naphathelene acetic acid, etc.

(c) Biological method: In this method, certain insects which feed on such weed plants are released on the crop field and they destroy the weed plants.
