Abstract
The inhibitory effect of aqueous extracts of fresh and dry leaves of myrthle; olive; orange. and fresh and dry fruits of pomegranate. on the growth of Alternaria alternata isolated from broad been leaves, were studied. Results showed that two aqueous extracts of fresh leaves of orange was highly active at concentrations 20, 40 mg/ml (93.33%) and at 10 mg/ml (87.77%). The other extracts, showed partial inhibition of growth of the test fungus. The aqueas extract of dry olive leaves inhibited the growth of A. alternaia (73.33%) at concentration 40 mg/ml. The aqueous extract of myrtle dry leaves gave no significant inhibition on the growth of the fungus
