Abstract
A study was conducted to investigate the effect of fertilizers with different carbon/nitrogen ratios (no carbon, NC; low carbon/nitrogen ratio, LC; high carbon/nitrogen ratio, HC) on Pythium aphanidermatum and on radish damping-off. The ratio of carbon to nitrogen applied in the field was 29, 22 and 0 in 2007 and 22, 17 and 0 in 2008 for HC, LC (as cattle manure) and NC, respectively. Field experiments over two growing seasons provided evidence for the lowest mortalities due to Pythium-induced radish damping-off to be in soil amended with LC (P0.05), which may imply a lack of evidence for the effect of carbon/nitrogen ratio on reproduction in P. aphanidermatum.
