Abstract<\/strong><\/p>\n\n\n\n

The study was conducted In Vitro<\/em> during\n2018-2019 at Plant Pathology Laboratory, Faculty of Agriculture, Omar\nAl-Mukhtar University, and aimed to evaluate the antagonistic effect local isolate of Trichoderma\nharizianum<\/em> against four pathogenic fungi (Botrytis cinerea, Macrophomina phaseolina,\nRhizoctonia solani and Sclerotinia sclertiorum<\/em>). Results showed that T. harzianum<\/em> isolate had good\nsignificant ability to inhibit the studied diseases fungi directly or\nindirectly.  Maximum rate of inhibition was 75.6%, and the\nhighest degree of inhibition according 4 in Sookchaoy scale against M.\nphaseolina<\/em>. The results of the microscopic examination showed the growth of the\nanti-fungus hyphae in parallel with the pathogenic hyphae and spirally wrapped\naround it, causing contraction and degradation them. Direct interaction between bio-control agent and the pathogens\ncausing different diameters in halos lysis of pathogens, also, volatile and non-volatile\nsubstances that released by T. harzianum<\/em> was recorded varying degrees of inhibition in all fungi, \nFinally, the bio-control agent produced antifungal\ncompound that can inhibit the growth of all fungi 100%.<\/p>\n\n\n\n

Keywords<\/strong>: Antagonism , Trichoderma harzianum<\/em>, Phytopathogenic fungi.<\/p>\n\n\n\n
