Parthenium Weed: From Challenge to Resolution

Author : Raj Nandini, Pankaj Nautiyal, C S Raghav, Renu Jethi

 

ABSTRACT

In India, the noxious weed Parthenium (Parthenium hysterophorus) is commonly referred to as congress grass, Gajar Ghas, carrot grass, or Dhanura. This aromatic, annual herb possesses an upright, branched growth pattern and an extensive root system. Its aggressive proliferation results in undesirable growth, primarily due to the copious production of spores. Parthenium exhibits remarkable adaptability, thriving in diverse soil types and a wide range of habitats. Following germination, the emerging plant forms a rosette at its base, displaying light green coloration, a hair-like structure, and deeply lobed leaves measuring 10-18 cm in length and 5-10 cm in width. This invasive species poses significant health risks, including contact dermatitis, allergic respiratory issues, and mutagenicity in both humans and livestock. To combat its spread, there is a growing trend towards adopting large-scale parthenium usage as a comprehensive approach to weed control. In agriculture, parthenium compost is also utilized, boasting higher nutrient content than vermicompost and Farm Yard Manure.
