What are weedicides?
The chemical methods involve killing of weeds by spraying certain chemicals called weedicides. Thus, weedicides are the chemical substances, which are used to destroy weeds present in a crop. Weedicides are also known as herbicides. Some of the common weedicides are:

a. MCPA [4-chloro-2-methyl phenoxy acetic acid]

b. Battachlor

c. 2, 4-D [2-4-dichlorophenoxyacetic acid]

d. TCA [trichloroacetic acid]

e. 2, 4, 5-T [2, 4, 5-trichlorophenoxyacetic acid].

In order to kill the weeds a solution of the weedicide is sprayed on the standing crops in the fields with the help of a sprayer. The weedicides kills the weeds selectively without damaging the crop. Weedicides are more effective in killing broad-leaved weeds.
