The vapour action of essential oils and monoterpenoids against pathogenic fungi

Abstract

The vapour action of pure monoterpenoids and volatile oils has been screened for their antifungal activity against four sugarcane pathogenic fungi using inverted petriplate method. Among tested monoterpenoids, menthol caused complete mycelial inhibition againstCurvularia pallescens at 2000 ppm, geraniol againstColletotrichum falcatum at 3000 ppm, linalool againstC. pallescens at 3000 ppm concentrations. Among tested essential oils, seed oil ofDaucus carota showed complete mycelial inhibition ofC. falcatum at 3000 ppm,Sugandh kokila oil againstC. falcatum at 3000 ppm,Curcuma aromatica againstC. falcatum at 3000 ppm andCurcuma zedoaria rhizome oil againstC. falcatum at 2000 ppm concentrations. Other doses of oils and monoterpenoids exhibited lower antifungal activity.
