Abstract

The antifungal activity of five plant extracts i.e., clove, cinnamon, jojoba, eucalyptus and christ’s thorn in comparison with the fungicide vitavax captan were evaluated In vitro and In vivo against damping- off fungi in lupin and chickpea seedlings. The tested fungi were Macrophomina phaseolina, Fusarium solani, Rhizoctonia solani and two isolates of Fusarium semitectum. Clove and eucalyptus oils strongly reduced the mycelial growth of the tested fungi, meanwhile the other three oils gave amoderate reduction. Dilution of oils variably reduced the mycelial growth of the tested fungi. Clove, jojoba and christ’s thorn oils significantly reduced pre-emergence damping-off in lupin and chick pea seedlings and increased the survival plants.
