Abstract

arthenium hysterophorus a noxious weed of today has its effect on human and animal health. This weed is known to cause asthama, bronchitis, dermatitis and hay fever in human and livestock. In a sample survey conducted in Bangalore, India it was recorded that 70% of the population suffers from allergic rhinitis due to pollen and 47% suffered from nasobranchial allergies. At present there is no effecteive treatment of dermatitis, other than exclusion of the weed but azathioprine therapy shows promising potential. Studies were undertaken to assess the phytosociology of Parthenium hysterophorus with other weeds growing in its vicinity and its control by some potent bio-agents. Studies were also undertaken to assess the chlorophyll content and percentage nitrogen of Parthenium hysterophorus. Maximum significant inhibition in chlorophyll content and percentage nitrogen was observed in shoot leacheates of Cassia occidentalis and Calotropis procera ,respectively.
