Abstract
The ethanol extract of leaves of psidium Guajava on Aspergillus Flavus and Fusarium Oxysporum was investigated invitro in Lab. A.Flavus and F.Oxysporum were collected by lab stock for the purpose of the study. The plant psidium guajava extract was constituted into five different concentrations (2%,4%,8%,12% and 20%). A potato dextrose Agar (PDA) was prepared according to my specifications for the growth of test organisms. In sterilized petri dishes containing a mixture of potato dextrose agar media and ethanol extracts the organisms were inoculated. The growth of the organisms reduced it is shown by the result. I know about the gowth inhibition of F.Oxysporum was higher compared to that of A.Flavus.
