Abstract

Damping off disease is caused by pathogenic fungi Rhizoctonia solani and Pythium debarianum. Its control is very difficult because of similarity of symptoms and use of non compatible fungicides for the target pathogens. The bigest problem is the dual infection which is very often, therefore the use of the proper control is necessary. According these facts, the aim of this study was to determine the most effective way of control. The investigations were carried out in tobacco beds, with two applications of fungicides. They were chosen by instructions, results from artificial inoculation and the previous practice. The most effective control is a fungicide who acts against two pathogens or combination who act separately to each pathogen or simultaneously. The highest effectiveness is achieved by Quadris 25 SC (250g/l azoxystrobin) at 0.15% - 100% effectiveness and Signum 33 WG (267 g/kg boscalid + 67g/kg pyraclostrobin) at 0.1% - 85.05%. Тwo combinations: Orvego (300g/l ametoctradin + 225g/l dimetomorph) at 0.1% + Manfil 80WP (800 g/kg mancozeb) at 0.25% - 88.64% and Orvego at 0.1% + Signum 33 WG at 0.1% - 84.23% effectiveness also achieved high results. These fungicides are excellent chemical control for damping off disease in dual infection by two pathogens in tobacco seedbeds. Keywords: damping off, fungicides, effectiveness, Quadris 25 SC, Signum 33 WG, Orvego
