Abstract

Rosmarinus officinalis is widely used for his anti-microbial activities .To this aim aqueous  methanolic and methanolic sonicaded  extracts of these plant were tested in vitro against deferent pathogenic strains: Fusarium oxysporum, Fusarium verticillioides, Fusarium gramanirum, Fusarium sp, penicillium sp, Alternaria sp,  Colletotrichum sp;, by the contact bioassay method using a 1 mg / ml concentration of each extract. The two methanolic and methanolic extracts sonicated reduced mycelial growth with an inhibition rate which varied from 36 to 90% for the methanol extract and 50 to 90% for the methanolic extract sonicated. On the other hand, the aqueous extract exerted a weak activity with an inhibition rate of 20 to 48%. From the perspective of the results obtained, the two methanolic and methanolic extracts sonicated can be used as biocontrols to protect from  fungal diseases.
