Abstract : Macrophomina phaseolina a soil inhabiting fungus that infects many plants causing some diseases. It was isolated from the roots of infected plants cultivated in Wadi Fatma and AI-Shafa areas, Saudi Arabia. The pathogenicity experiments of the fungus, on the test plant Squash (Cucurbita pepo CV Scarla) under glass house and wire green house conditions, revealed its severe pathogenicity. The pathogen has affected 23 different plant species and varieties, as its host range was tested. The physiological studies ofMphaseolina indicated that the media of potato dextrose, malt and Czapek's were the best for fungal growth. Incubation temperature of 30°C, pH ranges between 5.1 and 5.9, as wen as a relative humidity of 1000.10 were responsible for maximal growth of the experimental mould. It was also able to assimilate different carbon sources ofwbich glucose and sucrose were the best tested. The fungus exhibited high enzymatic activity of pectin methyl estrase, polygalacturonase, cellulase and proteases. Antagonistic studies indicated that, of the microorganisms isolated from rhizophore of Squash, Bacillus subtilis was the most active species against Miphaseolina growth
