The effect of pre-sowing seed treatment on the elements of the crop structure and the phytosanitary condition of spring wheat seeds of the Novosibirsk 31 variety

The article presents the results of studies on the study of preparations for pre-sowing dressing of spring wheat seeds. The research results showed that pre-sowing seed treatment did not have a significant effect on the germination and coleoptile height of wheat seedlings. The use of a solution of a silicon-containing plant growth and development stimulator with a fungicidal effect, enriched with microelements, has significantly significant differences in the morphometric parameters of wheat seedlings (p = 0.000-0.048). The use of a spore-based biological fungicide stimulated the development of pathogenic microflora (p = 0.045). Seed treatment of a preparation based on a biopolymer enriched with silver and copper nanoparticles helps to reduce the development of pathogenic microflora (p = 0.017).
