Treatment of mineral soil with aerated steam at 54.4 C for 15 min eliminated Dactylium dendroides, Geotrichum candidum, Mycogone perniciosa, Ostrachoderma sp., Trichoderma viride, and Verticillium malthousei that had been experimentally established for 17 days in axenic soil culture. Repeated experiments with T. viride and Ostrachoderma sp. yielded inconsistent data when treatment time was 15 min, although they were consistently eliminated with 30 min treatment.
