Explanation
Parthenium hysterophorus is commonly known as congress grass or carrot weed. It is a herbaceous annual plant of the Family Asteraceae. It is a deadly invasive, noxious weed infesting cropped and noncropped areas. It rapidly colonizes areas, replacing the native vegetation and causing a number of human health-related problems such as skin allergy, rhinitis, and eye irritations. Also, being toxic and unpalatable it causes fodder scarcity. Hence, it is considered a threat to the biodiversity.
