| Abstract | ||
| The study is made to enhance the quality of the fury T.viride and T.harzianum in protection black seeds from infecting with the field fury is F.lateritium , F.solani , Rhizoctonia sp. and their effect on growing and the positive effect of T.harzianum and T.viride in improving the germination percentage , plant length and dried weight of the vegetation and root system especially for isolating the fungus T.viride if the features measure the growth by (70% , 16.16cm , 0.330g , 0.120g ) respectively in comparative with others ( 64.66% , 11.66cm , 0.123g , 0.053g) The results shown that adding biocontrol agent T. harzianum didn't gave positive results in controlling fungi pathogen F. solani , F. lateritium & Rhizoctonia sp. While adding biocontrol agent T.viride with fungi F. solani & Rhizoctonia sp. Significantly improve the plant features , but failure in control fungus F. lateritium . | ||
