Definition of Weeds –
A weed is a plant growing where it is not wanted. Weeds compete with planted crops for light, space, nutrients and water. They grow very fast and easily crowd the farm or garden, leaving less space for crops to grow well.

Examples of common weeds are:
- Guinea grass
- Spear grass
- Siam weed
- Wild spinach
- Goat weed
- Elephant grass etc.
