Fusarium root disease is a common and often serious problem in the production of container-grown seedlings. Fungicide treatments applied late in the growing season, i.e. during bud initiation stress, are relatively ineffective against the disease. Incorporating a granular mixture of etridiazole and thiophanate-methyl fungicide (Banrot) into the medium prior to sowing was tested for tis efficacy of control against the disease. The fungicide was unable to sufficiently reduce Fusarium infection and infection intensity enough to warrant its use in root rot management. Some phototoxic effects were observed.
