| Abstract | ||
| This study included testing the efficacy of two fungal filtrates of Trichoderma harzianum and Trichoderma aureoviride and the chemical compounds of ammonium chloride and calcium chloride in the radial growth and germination of spores of the pathogenic fungus Fusarium oxysporum isolated from the seeds and roots tomato in measuring with fungicide (Topsin), as well as test the effect of these treatments on the germination of the seeds of tomato in sterilized and unsterilized soil,It also has been diagnosed pathogenic fungus F. oxysporum using a technique Polymerase Chain Reaction (PCR). The results showed that all treatments salts and filtrates have a significant inhibitory effect to the growth for the fungus F. oxysporum on the solid culture medium P.D.A in measuring with controlled treatment at the level possibility 5%,as it was for these treatments have a significant inhibitory effect to the germination of spores for the tested fungus, as well as the back of a clear effect in raising the percentage of germination of the seeds of tomato in sterilized and un sterilized soil, and It was the concentration 15% of the filtrates and 15 mg/ml of salts most influential in measuring with other concentrations and fungicide (Topsin) at concentration of 1mg/ml . | ||
