— The damping off disease of tobacco seedlings caused by the pathogen Rhizoctonia solani causes a huge damage. The limited numbers of products are used in protection from the disease, but lately new fungicides appeared on the market. The aim of these investigations was to determine the effectiveness of new fungicides in control of this pathogen, compared with commonly used. The tests were carried out in conditions in vitro, with 8 fungicides. Two fungicides were evaluated in 2 or 3 concentrations. All tested fungicides showed extremely high effectiveness in the control of this pathogenic fungus –the percentage of inhibition of radial growth ranges from 80, 45 to 100%. The preparate Orvego (300 g / l ametoctradin + 225 g / l dimetomorph) is exception –it showed 48.05%. The best effectiveness showed contact fungicides Manfil 80WP (800 g/kg mancozeb) and Enervin WG (120 g/kg ametotradin +440 g/kg metiram) as well as systemic Signum 33 WG (267 g/kg boscalid +67g/kg pyraclostrobin) and Quadris 25 SC (250 g/l azoxystrobin)with100%inhibition of pathogenʼs development. Fungicides with such high effectiveness in control of R.solani will ensure their use in protection of tobacco seedling from the damping off disease.
