The inhibitory effect of the aqueous and acetonic plant extracts of Eugenia caryophyllata and Cinnamomum zeylnicum against some phytopathogenic fungi

Abstract

This study included the efficacy of the aqueous and acetonic extracts of E. caryophyllata and C. zeylnicum and the fungicide Top tapsin 70% in the growth of some phytopathogenic fungi which include: A. niger, A. flavus and N. crassa that are isolated from infected fruits and vegetables , through their effect in mycelial growth. The phytochemical screening of the active ingredients showed that the aqueous and acetonic plant extracts of E. caryophyllata and C. zeylnicum contained tannins, saponins, resins, flavonoids, alkaloids, fuocoumarins and terpenes. The results showed that the aqueous and acetonic extracts of E.caryophyllata and C.zeylnicum have significant inhibitory effect for growth of phytopathogenic fungi on solid culture medium ( PDA ) , in measuring with controlled treatment at level of probability 5% , where the aqueous and acetonic extracts have high inhibition percentages at concentration ( 30ml ) and these extracts gave higher inhibition percentages than Top tapsin 70 % at a various concentrations.
