摘要：

The survival of Plasmodiophora brassicae was studied at digestion temperatures of 35-degrees-C and 55-degrees-C in laboratory batch digesters within one and two weeks, respectively. The study showed that digestion at 55-degrees-C almost completely reduced the ability of infecting bait plants. The seeds of Rumex obtusifolius and Lycopersicon lycopersicum (tomatoes) were completely destroyed at 55-degrees-C and a digestion time of 14 days, in laboratory batch digesters. The experiments carried out in a two stage pilot plant (Leach-Bed Solid Phase batch Digester for hydrolysis and a pulsating dynamic anaerobic filter for methanogenesis ) showed that hydrolytic conditions are mainly responsible for the killing of weed seeds. Some additional data on the qualities of different digested substrates are presented.
