S-H mixture used as soil amendment at the rates of 0.5 to 2% (w/w) greatly or completely inhibited damping off and root rot of cucumber caused by Pythium aphanidermatum under the greenhouse and field conditions. Among the various combinations of the components of S-H mixture tested in laboratory, urea was the main factor for the inhibition of oospore survival and mycelial growth of the pathogen. Siliceous slag had some additive effect. Urea alone was almost as effective as S-H mixture in reducing the pathogen population and suppressing the disease, but the gained suppressiveness was lost after 25 days of incubation. Soil amended with urea plus siliceous slag remained suppressive at least for 28 days, the longest incubation period conducted in this study.
