The aim of this study is determination of polyphenol contents and biofungicide activity of crude
extract of Datura stramonium. The results of extraction showed an important yield percentage of
crud extract equal 25.22 % wherase, the polyphenol content of the extract was 657,0 (mg AGE/ml
Ext). The In vitro biofungicide activity carried out by disk diffusion method, the biofungicide effect
results performed with crude extract and Milraz WP 76 fungicide (Propineb 70%, Cymoxanil 6%)
against fungal strains. The results appear that natural substances possess an antifungal power on the
multiresistant germs responsible for infectious diseases for plants. Growth inhibition varies
depending on the fungal strains and the concentration of the test product
