@biospeaks4u: Parthenium hysterophorus is a highly invasive weed commonly known as Congress grass or carrot weed. It spreads rapidly in fields, roadsides, and open lands, especially in tropical and subtropical regions like Pakistan. Small white flowers arranged in clusters Deeply divided green leaves Can grow up to 1–1.5 meters tall Produces a large number of seeds (fast spreading) Harmful Effects: Causes skin allergies, itching, and respiratory problems in humans Toxic to animals if consumed Reduces crop yield by competing for nutrients and water Releases chemicals (allelopathy) that inhibit growth of nearby plants Control Methods: Manual removal (with gloves to avoid skin contact) Use of herbicides Biological control (insects like Zygogramma bicolorata) Preventing seed spread #Parthenium #CongressGrass #InvasiveWeed #PlantBiology #EnvironmentalIssue
