Abstract
Different isolates of Fussriurn oxysporum f.sp. lycopersici were isolated from tomato plants infected with wilt collected from tomato fields located at different locations of Ismaillia, Giza and Minia. These isolates differed significantly in their virulence to induce wilt disease of tomato. The present virulent isolates were found to cause wilt disease only 10 tomato. These isolates were then considered specialized which named F. oxysporum f.sp",lycopersici. tn taborato!), tes·~s. the growth of the mentioned pathogen was highly inhibited by 75.5% • 70.3% as a result of the antagonistic effect of Streptomyces spp. and pseudomonas fiuorescens. The growth of different isolates of the tested fungus were completety inhibited at concentrations 100 and 400 ppm of Topsin M and Tecto' Mancozeb. respectively. Application of biological and fungicidal treatments reduced wilt incidence of tomato grown under field conditions. Combination between Topsin M and soil drench with Streptomyces spp < /em>. or Pseudomonas fluorescens. Induced more significant reduction in disease incidence and yietd increase than seed coating with bioagents and' or each treatment alone. Data of this study indicated thai the combined biological and chemical treatments could be considered as promising technique for application to controt certain soli bome fungi causing wilt disease. Perspective application of integration technique may held to decrease the usage of fungicides and reduce environmental pollution. I
