A Weed of Global Significance Parthenium hysterophorus L.: An Overview of two faces of Parthenium weeds.

Abstract

The noxious and invasive weed Parthenium hysterophorus L., commonly known as "famine weed" or "congress grass," poses significant risks to human health, agriculture, and biodiversity. Renowned for its rapid and aggressive growth, as well as allelopathic characteristics inhibiting the growth of natural vegetation and desirable crops, this abstract provides an overview of both the drawbacks and potential uses of Parthenium hysterophorus. Various control methods, including mechanical removal, chemical herbicides, introduction of biological control agents, and cultural practices, are employed to counteract its proliferation. Integrated techniques are often recommended for effective management. Despite its adverse effects, Parthenium hysterophorus exhibits some positive attributes. Notably, it possesses therapeutic properties, and ongoing research suggests its potential applications in phytoremediation and biofuel synthesis. Emphasizing the critical need for proper Parthenium hysterophorus management, this abstract underscores the importance of comprehensive, long-term solutions to address this environmental menace while exploring its potential benefits
