Mechanical method- Involves pulling out weeds with hands or by ploughing. Weeds can also be removed using a big comb-like harrow or using a trowel.
Cultural method: Cultural methods of weed control include proper bed preparation, timely sowing of crops, intercropping and crop rotation.
Chemical method: involve the use of chemical weed killers called herbicides such as 2,4-D, atrazine, fluchloralin, and isoproturon to kill the weeds.
Biological method: involves the deliberate use of insects or some other organisms which consume and specifically destroy weed plants.
