What are Weeds

Innumerable plants are produced in nature.  But a farmer cultivates only those plants that are needed by him.  So far as nature is concerned there is no such preference.  It is when plants grow where they are not required by man that it becomes a weed!  But in nature a weed and a favourite plant may be the same thing!
In several instances weeds have a special ability for rapid and luxuriant growth.  Weeds cause an annual agricultural loss of many millions of Rupees.
The best way to eliminate them is to use weed-free seed.  There are other methods too to control them effectively by farmers.  They are crop rotation, clean cultivation, use of  herbicide etc.

But we should not forget that most of the plants that exist in nature are unwanted, wild varieties.  The beauty of the countryside is mainly due to them.  They help to retain moisture of the soil and prevent soil erosion.
