Weed becomes invasive menace: Toxic Parthenium spreads across the country; India fights back with beetles
Parthenium hysterophorus, a weed from Mexico, entered India hidden in American wheat decades ago. This invasive plant now chokes roadsides and fields, spreading rapidly across the nation. Its pollen causes severe allergic reactions and respiratory problems in many people. The weed also suppresses crop growth and reduces fodder productivity for livestock. Biological control using a Mexican beetle and public awareness are key to managing this threat.
