The tomato powdery mildew (Oidium lycopersicum) was at first recorded in 1988 in the Czech Republic. Pathogen was observed only on greenhouses crops of tomato. Some genotypes of Lycopersicon hirsutum, L. parviflorum and L. pennellii were found moderately resistant and this species may be used in breeding of new tomato resistant cultivars. There is only limited information about host range of this pathogen and about possibility of transfer of powdery mildew from other species of Solanaceae to the tomato.
