Antifungal Activity of Aroma Chemicals Against Seed-borne Fungi

Abstract

Abstract In vitro inhibition of 16 aroma chemicals was studied against five seed-borne fungal pathogens in the concentration range of 100 to 8000 ppm: Drechslera sorokiniana (Sacc.) Subram. et Jain, Phomompsis sojae Leh., Fusarium solani (Mart.) Sacc., Colletotrichum graminicola (Ces.) Wilson and Macrophomina phaseolina (Tassi) Goid. Minimum inhibitory concentration (MIC) was computed for each chemical against each fungus. All the chemicals had shown dose-dependent inhibitory effect of mycelial growth. Eugenol, methyl eugenol, citral, 2-phenethyl alcohol, 2-phenethyl acetate and 2-phenethyl propionate were found to be highly effective against all the test fungi with MIC values of 270 to 1704 ppm and potentially hold promise in plant disease management and plant quarantine.
