| Abstract | ||
| The study was conducted to explore the biological activity of water and alcoholic extracts of N.oleander L: leaves (Fresh & dry)against the growth of some plant pathogenic fungi namely; Alternaria alternata, Macrophomina phaseolina & fusarium oxysporum In general the inhibition effects of water extracts varied between(6.7-81.3)% while the alcoholic extracts achieved different percentage and the inhibition effects varied between (33.3 & 93.3)% in both fresh and dry leaves . For comparison purposes Captan was used at different concentrations and achieved 100% inhibition at (0.8,1 & 2 mgml). Chemical analysis of Nerium oleander L. leaves proved the presence of alkaloids , flavenoids ,resins phenols, tanins,saponis & glycosides . | ||
