Abstract

This research was carried out to evaluate the effect of food supplement DXN-Ganoderma, produced from the red fungus Ganoderma lucidum and DXN- Spirulina from spirulina platensis on the Tobacco mosaic virus in the virus research lab / College of Agriculture / Tikrit University. The virus was diagnosed with RT-PCR. The S. platensis was superior in reducing the TMV virus on all varieties as the values by 64.4% on Syrian variety, 75.00% Black Hybrid variety, and 82.4% of Iraqi variety. Also S. platensis reduced TMV infection to 33.4% compared to 70.01% in with the treatment TMV alone. The treatment of S. platensis, and fungus G. lucidum were given significant differences in Chlorophyll, plant height, leaf area as they reached 54.4 spad, 52.7cm and , 71.3cm² respectively, compared to34.3 spad, 22.9 cm and 17.5 cm2 respectively. While the treatment of fungus G. lucidum and algae S. platensis increased growth indicators for eggplant plants of root, shoot dry weight and the yield were, 17.3gm , 129.2gm and 4.572 kg respectively, compared to 6.3gm, 22.9cm, 0.450 kg, respectively.Keywords: Tobacco mosaic virus, Spirulina platensis, Ganoderma lucidum, Eggplant.
