SUMMARY In growth room experiments, treatment of wheat seed with phenyl mercuric acetate significantly reduced seedling disease caused by soil‐borne Fusarium culmorum, F. nivale and F. avenaceum in inoculated soil. Seed treatment improved the low germination caused by F. culmorum , but did not affect the reduced seedling vigour caused by F. nivale. Seed treatment was normally as effective in conditions favouring disease as it was in less favourable conditions. Conditions favouring disease in soil inoculated with F. culmorum were high inoculum level, deep sowing and dry soil.
