Level of infection with Tilletia caries (DC.) Tul. and Tilletia laevis Kühn of winter wheat ears and efficacy of control of these pathogens.
Experiment was performed in the seasons 2003/2004 and 2004/2005 on winter wheat cv 'Mikon'. In this paper per cent of ears infected with Tilletia caries and Tilletia laevis and per cent of bunted seeds in infected ears was evaluated. Efficacy of control of T. caries and T. laevis with seed treatment was also discussed. Artificial inoculation was performed before sowing. Seeds were inoculated with teliospores of one or two pathogens in various rates. To evaluate the efficacy of control of T. caries and T. laevis, inoculated seeds were treated with Raxil 060 FS (tebuconazole). Average per cent of infected ears in experimental objects varied from 9.5 to 22.8. In infected ears 90.7% to 91.8% of seeds were bunted, on an average. Efficacy of control of T. caries and T. laevis was 100%.
