The researches had aimed determining the effectiveness of Trichoderma harzianum (T-22) fungus, in to prevent soil pathogens (Pythium spp, etc.) in petunia seedlings. Selling of this hybrid stalk is made as the product called Trianum. The product contains spores of the fungus and was used as a solution in concentrations 0.08% and 0.1%; the treatments were applied on the nutritive substrate, after sown or after plants emergence. Experience was realized in 2012, on petunia healthy seedlings, in the pilot greenhouse of the Institute Horting Bucharest. The hybrids studied were Dreams Midnight, Dreams Wihte, Dreams Red. The nutritive substrate were peat fertilized middle. It was evidenced efficacy the product on the soil pathogens that cause "the fall of seedlings" (Pythium spp.). After research, it was concluded that the product have optimal effect in preventing this vascular disease on petunia seedlings; the fungicide had best biological efficacy on the Dreams Midnight hybrid, applied after plants emergence, in concentration 0.08 %.
