When selecting seed dressers, preference is given to preparations with a combined effect that provide both protection and treatment and kill both the external and internal infection of the seed. The results of the mycological analysis of the soil showed that pathogens predominate over suppressors. Among the pathogens, fungi of the genus Fusarium are the most common. The strongest infection with Fusarium and bacterioses was found on winter wheat grains of the Pamyat and Etnos varieties. The fungicides Maksim Forte, EC (containing tebuconazole 15 g/l, fludioxonil 25 g/l and azoxystrobin 10 g/l) and Kinto Plus, SC (containing fluxapyroxad 33.3 g/l, triticonazole 33.3 g/l and fludioxonil 33.3 g/l) showed a high protective effect against bacterial and Fusarium infection of winter wheat seeds.
The laboratory germination of the seeds in the control without treatment was 76.7 %. Treatment of the wheat seeds with fungicides increased germination by reducing the level of bacterial and fusarium seed infection: Maksim Forte, SC – 88.7 % and Kinto Plus, SC – 90.1 %.
Keywords: winter wheat grain, seed infection, seed dressers.
