STUDIES ON HERBICIDAL ACTIVITY OF PARTHENIN, A CONSTITUENT OF PARTHENIUM HYSTEROPHORUS, TOWARDS BILLGOAT WEED (AGERATUM CONYZOIDES)

摘要

Parthenin, a constituent of Parthenium hysterophorus, was evaluated for herbicidal activity against Ageratum conyzoides (billgoat weed) under irt vitro conditions. It inhibited/retarded germination of A, conyzoides at concentrations ranging from 0.02 to 0.1 mg/ml. Radicle elongation and seedling length were severely reduced. The germination of wheat, however, remained unaffected at similar concentrations. The study, therefore, paves a way for possible exploitation of parthenin as a selective herbicide. [References: 13]
