Influence of Sugar Beet Seed Treatment with Pseudomonas fluorescens and Low Fungicide Doses on Infection with Pythium and Plant Yield and Quality

The effect of sugar beet seed inoculation with the bacterium Pseudomonas fluorescens and treatment with the fungicides Thiram 42-S and Dithane S-60 with and without seed inoculation aiming to control the root decay agents Pythium ultimum and Pythium debarianum was studied during a 2-year trial on two soil types (Mollic Gleysols and Eutric Cambisols). The influence of the treatments on parameters of sugar beet yield and quality such as root yield, sugar content, sugar in molasses, sugar yield as well as percentage of the infected and decayed plants as a consequence of parasitic oomycete infestation will be described
