Results in Table (1) showed that, orange oil at all tested
concentrations was a significant reducing the fungal linear
growth if compared with other tested essential oils . At low
concentration 50 (µg/ml) orange oil caused 10.0% reduction
in fungal growth, while at 100 (µg/ml) caused 72.2% and at
high tested concentration 150 (µg/ml) caused a complete
reduction in mycelium linear growth of pathogenic fungus.
On the other hand, basil oil gave a moderate effect to
reducing the fungal linear growth at all tested concentrations
by 5.5, 20.8 and 38.5%, respectively. Lemon and mustard oil
showed a lower effect at all tested concentrations if
compared with the other oils and control treatments
