Answer 2

Answer:

Weeds are controlled by chemicals called Weedicides.

Explanation:

Weeds are the unwanted plants that grow along with the crops and compete with them for nutrition, reducing their availability to the crops and hence impeding their growth. For better agricultural productivity the growth of these weeds must be restricted.  

Weeds can be killed by certain chemicals called weedicides. They are sprayed across the fields to kill specific target plants while leaving the desired crop relatively unharmed.

Some of the commonly used weedicides are:

• Naphthalene acetic acid
• Glyphosate SL
• Atrazine, Metribuzin WP
• 2 4 Dichlorophenoxy acetic acid
