Explanation:

Xanthium and Parthenium are called weeds.

Weeds grow simultaneously with the crop plants in a crop field. They grow very fast and take up all the necessary nutrients and water from the soil. As a result the crop plants do not get nutrition and they cannot grow as desired.

Methods of weed control:

Application of herbicides control weeds very fast.

Hand picking of weed plants are also done.

Regular mowing of weeds is effective to suppress their growth.

Biological control of weeds are possible by using insects, bacteria, fungi etc. as agents.
