Efficacy of fungicides for seed treatment against Tilletia tritici in North-Western part of Bosnia
The results of a two-years investigation of the efficacy of fungicides used for seed treatments of the winter wheat variety Zlatka against T. tritici are presented. The following fungicides designed for seed disinfection were used: Dividend 030 FS, Vitavax 200 FF, Raxil 060 FS, Panoctine 350 IS. All of the tested fungicides were found to be highly effective, the top efficacy being archived by Dividend 030 FS, followed by Vitavax 200 FF (99.99%), Raxil 060 FS (99.98%), and Panoctine 350 (99.96%). Such high efficacy shows that it would be desirable to increase the use of these wheat seed disinfectants in North-Western Bosnia. Wheat yields were found to increase 15.5 - 26.3% in 2003 and 15.6 - 28.9% in 2004, compared to control. The differences in yields, in relation to control, were statistically significant, while the effect of fungicide treatments on weight per thousand kernels and hectolitre mass of seeds was not statistically significant.
