Abstract
A wilt disease including severe root rot and corky rot was observed near the end of the growing season in glasshouse tomato (Lycopersicon esculentum) plants, growing in soilless systems. Numerous aleuroconidia of the common soil-borne fungusHumicola fuscoatra var.fuscoatra were always present in the cells of affected roots. The pathogenicity ofH. fuscoatra was not established, but inoculation with previously used rockwool from a crop with corky root symptoms reproduced the disease. It is suggested that near the end of the growing season the artificial substrate offers favourable conditions for the development of a complex root disease in whichH. fuscoatra may play a role.
