| Abstract | ||
| This study was aimed to evaluate the affectivity ofchemicalfactorBION and biological factors of fungi (Beauveriabassiana,Trichodermaharzianum ) and singularly or collectively in reduce of plant tomato by diseasecalledfusarium wilt disease caused by Fusariumoxysporum f. sp. Lycopersici. Result of induce systemic resistance in tomato plant,that the B. bassiana showed increasing in phenoles reach 19.7 mg/g followed by T. harzianumwhenrecording 17.9mg/g. BeauveriabassianaandTrichodermaharzianum together increas Peroxidase (PO) and Phenylalanine ammonia-lyase(PAL) enzymes amount, PO reached 29.9min/gfw and20.6 min/gfwrespectively,WhilPAL enzyme recored 28.5µg/hour/gfw and 22.7 cinnamicacid µg/hour/gfw respectively .BeauveriabassianaandTrichodermaharzianumshowedexcel in seeds treatments causing signficant reduction in infection percent ,disease severity ,disease index and disease coefficient , B. bassianarecor 9.3%, 0.5, 10.2% and 0.2 respectively,Trichodermaharzianumrecored 10.5%,0.6,12.2%and 0.2respectivty .This induceing resistance reflected positively on root volumfreash weight and dry weight of plant compeared with FOL treatment alone. BeauveriabassianaandTrichodermaharzianumsignificant increased in root volume at rate of 43.3cm3 and 40.7cm3 respectively ,recording 340g and 346g fresh weight of shootes, 34.6g,33.6g fresh weight of root respectively , these treatment record 110g and 97g shoot dry weight respectively and5.3 g 3.3g root dry weight respectively, compared with control treatment with fung. | ||
