Complementing biological control with plant suppression: Implications for improved management of parthenium weed (Parthenium hysterophorus L.)

► Biological control agents and suppressive plants can act synergistically under field conditions. ► The combined action resulted in a greater reduction of parthenium weed biomass than either technique alone. ► Suppressive plants enabled greater fodder production in the presence of biological control agents of parthenium weed.
