Abstract:\u00a0<\/strong><\/span><\/p>\n

\u00a0 This study showed the ability of two isolates of the pathogenic fungus A.alternata <\/em>in the water agar medium. The isolate of fruits had the most effect on the severity of infection of tomato seeds in the dish, reaching 59% compared to isolate the leaves, which amounted to 47%. The results of the antagonism test for T.viride<\/em> and T. .koningii<\/em> in PDA culture medium had a high antagonistic ability against A.alternata<\/em> by spot method, the inhibition zone reached (2.3, 1.8), respectively. The filtrates of biological resistance fungi showed inhibition of the pathogenic fungus A.alternata<\/em> when used at concentrations of (10,20,30)% with PDA culture medium. When analyzing the infiltrates of T.viride<\/em> and T.koningii<\/em> using GC-MS technique, several chemical compounds that have a role in inhibiting pathogens were obtained, including n-Hexadecanoic acid and Octadecanoic acid. As for the total phenol content in the leaves of the tomato plant, T.konhngii<\/em> treatment gave the highest content of phenol, as it reached 0.56 mg. Also, chlorophyll was increased in tomato leaves, so the T.v<\/em> + T.k<\/em> treatment gave the highest percentage of chlorophyll, which amounted to 47.55 mg, compared to the fungus A.alternata<\/em> treatment, which amounted to 36.13 mg .The biological resistance fungi also reduced the severity of infection with the pathogenic fungus A.alternata,<\/em> which amounted to 19.66% in the treatment of T.konhngii<\/em>, compared to the treatment of the pathogenic fungus, which amounted to 50.36%.<\/span><\/p>\n
