Weeds can be defined as the unwanted plants that grow in the field along with the crops. Most of the weed infestation is observed during the kharif season. Weeds are classified into narrow-leaf weeds and broad-leaf weeds on the basis of their morphology.
(i) Narrow-leaf weeds are a type of monocot weeds that can infest crops during kharif as well as rabi season. Typical examples of narrow leaved rabi season weeds include Wild oat (Jangali jaii) and Phalaris (Mandoosi).
(ii) Broad-leaf weeds are dicot weeds. Examples of broad-leaved kharif season weeds include Xanthium strumarium (Gokhroo) and Amaranthus viridis (Chaulii).
