In the conditions of the Republic of Belarus there were analyzed the most effective preparations for the of protection of white cabbage (Brassica oleracea convar. capitata var. alba L.) seed plants against mucous bacteriosis (Erwinia carotovora subsp. carotovora (Jones) Berqey, Harrison et al.) which also provided high seed yield with high seed qualities. There was studied the efficiency of preparations Izar, 10% aquatic concentrate (polyhexamethylene guanidine hydrochloride in dose 30 ml/10 l water); Prestizh suspension concentrates (140 g/l of imidacroprid + 150 g/l of pencikuron in dose 50 ml/10 l water); Tetramethylthiuram disulphide, water-suspension concentrate (thiram, 400 g/l in dose of 50 ml/10 l water); Phytolavin (a complex of strreptotrycin antibiotics in dose 50 g/10 l water) were tested on cabbage seed plants of Nadzeya variety which was included into the State Register of Varieties and Hardy-shrub Species. Preparation Fundazol 50 wettable powder (benomyl, 500 g/kg in dose 50 g/10 l water) was applied as a sample. Research results showed that all analyzed preparations decreased the level of development of mucous bacteriosis of cabbage. Application of Izar and Prestizh decreased the intensity of disease development on 11,8-11,9% in comparison with control (31,1%) and on 4,4-4,5% - in comparison with a sample (23,7%) preparation. Lowering of seed plants prevalence with mucous bacteriosis increased the seed yield. The highest yielding capacity of seed cabbage (9,0 and 9,4 centner/ha) was obtained after application of Izar and Prestid.
