What is a Weed Plant?

A weed is “a plant in the wrong place” or an undesirable plant that has taken root in an unintended location. This depicts the motivations of humans in any given circumstance.

Weeds are undesirable, invasive, harmful, and inhibit the growth of other crop plants, negatively affecting human activities, agriculture, natural processes, and a country’s economy.

Weeds can inhibit crop growth by the following means:

  • Competition for resources such as light, water, and nutrients can reduce the quality and yield of produce.
  • Successfully attempt to cause damage to harvesting equipment
  • Existence of potentially harmful organisms and pests.
