| Abstract | ||
| Alkaloids extract of Datura stramonium L .(leaf),and peganum harmala(seed),and oils of Myrtus communis (leaf) and of Eugenia carophyllus (flower). Were extracted and their inhibitory activity was tested against the fungi Alternaria alternatia , Macrophomina phaseolina, Aspergillus niger and Fusarium oxysporium , A.alternatia was the most sensitive species (96%) when leaf extract alkaloids of Datura Stramonium was used,while A.niger was the most effected (73.3%) when seed of extract rait alkaloids of peganum harmala was used of final concentration of 0.5 mg/ml of the medium. A.alternata was highly in habited(93.3%) when treated with leaf oils of Myrtus communis, while A.niger was highly effected (96%)when subjected to treatment withe flower oils of Eugenia carophyllus. Complet inhibition of A.alternata and F.oxysporium were achieved when mixture of alkaloids of afinal can contration of 0.5 mg/ml was used, complet inhibition of A.niger was also achieved when amixture of oils at concentration 0.03 mg/ml was used,complet inhibition of A.alternata was observed at final concentration 0.1 mg/ml of the medium | ||
