| Summary: | Spodoptera litura (Fabricius) is the most serious pest of many cultivated and non-cultivated crops and it developed resistance against many synthetic pesticides. The impact of a Compositae annual weed, Synedrella nodifl ora Gaertn. solvent extracts on the fourth instar larvae of S. litura has been evaluated by leaf dip method. The LD50 results revealed that methanol extract is the most toxic to the pest followed by benzene and chloroform, petroleum ether (400 – 600 C) and water. Qualitative phytochemical analysis has also been performed. |
