Abstract

                                Seed extracts of Coriandrum sativum Cuminum cyminum, Foeniculum vulgare and Trachyspermum ammi were screened against Pythium ephanidrmarum Macrophumina phaseolina and Rhizoctonia solani. Seed extracts of T. ami showed high antifungal potentiality as it inhibited. mycelial growth of all three fungi tested. The extracts from seeds of the other three could inhibit mycelial growth of P. aphanidermatum only. The essential oils of four plant seeds exhibited strong fungitoxicity as they completely checked mycelial groath of all the tested fungi, even at very loa concentrations. These ells were not found phytotoxic on seed germination, seedling growth, general health and morphology of thindi (Abelmaschus esculentusi.

Key words : Antifungal activity, seed extracts, essential oils, soil-borne phytopathogens
