The work was undertaken to investigate the Fungitoxic, Phytotoxic potential and Insect repellent activity of essential oil of Casssia tora against two test fungi viz., Aspergillus flavus and Fusarium moniliforme and test insect Sitophilus oryzae. The essential oil of Cassia tora remained fungitoxic against both the test fungi at 1.0 X 103 µL/L concentration. When paddy seeds were exposed to selected essential oil at the same concentration, no phytotoxicity was observed in seed germination and seedling growth under in vitro conditions. The selected essential oil also showed repellent activity against the test insect Sitophilus oryzae, which damages the stored grains and reduces the nutritional value.
