The efficacy of these extracts against the growth of the fungus (Penicillium digitatum )and its spore colonies was also studied the results showed that the upper inhibited percentage for growth fungi by seed oil was 84% at 20000ppm, while the lower inhibited percentage at 7500ppm was 81%.

The inhibited percentage by using ethanol extract was 84% at 20000ppm and 76% at 2500ppm .

The efficacy of extracts against spores of fungi was 100% at 20000ppm, while it was 55% and 50% by oil and ethanol extracts, respectively at 2500ppm.
