Sažetak
The wheat seed, artificially contaminated by the spores Tilletia tritici 3,5 g/kg, was treated by Radosan (Hg) and the derivate 8-Quinolinol (L₂₀, L₃₀, LC₂₀, LC₃₀, LB₂₀, LB₃₀ and L 5,7 C) - all in the dose 250 g/q. The results of the laboratory test with the spores greased to the groung in Petri disehes show that the spores from the untreated seed (K - of bright colour of the spores) germinated good. The germination of the spores from the seed treated by L₂₀ was impeded to some extent, the spores from the seed, treated by L₃₀ and Hg had no germination (spores, greased black). Phot. 1. In the field test was found out that the derivate 8-Quinolinol LC₃₀ has significantly the greatest effect, LC₂₀ in equalmto Hg (Tab. 3). All the derivates had the weaker effect from Hg, however all showed the stronger or weaker fungicide effect in comparison with the untreated seed (K). From the result it can be seen according to the total number of ears the treating by the derivates 8-Quinolinol did not reduced the number of plants (Tab. 1).
