: In this study we have investigated the effect of T. harzianum on growth,content of chlorophyll and epidermal flavonols and metal distribution in tomato plants.Trichoderma strain, isolated from the A horizon (5–30 cm) of agricultural soil used in organicproduction, was applied near the root in the sixth leaf development phase of tomato. Tomatoplants were grown in a growth cabinet up to the stage of 10 leaves. Content of chlorophyll (Chl),epidermal flavonols (Flav) and antocyanins (Ant) were measured in vivo non-destructively.The concentration of Cd, Co, Cu, Cr, Fe, Mn, Ni, Se, and Zn was measured in different partsof tomato plants by ICP-OES method. Results have shown that Trichoderma applicationpositively affected growth of tomato plants, and significantly decreased nitrogen balanceindex. In Trichoderma treated plants the contents of Cr and Ni were significantly reducedin roots, while content of Cd tended to decrease in all plant parts, significantly in roots.Presented results indicate that investigated isolate is worthwhile testing for plant growthpromotion in field conditions, taking in account different supply of macro and micronutrients
