Presented are the experimental data on the effect of biofungicides on seed infection and mycoflora of winter wheat seeds of varieties ‘Levada’ and ‘Podolyanka’. The phytostudy which was conducted allowed to determine the presence of micromycetes such as Alternaria alternata (infection rate 6.8–19.5 %), Tilletia caries (1–2 %), Fusarium spp. (0.5–3.5 %), Cladosporium herbarum (1.5–3.5 %), Bipolaris sorokiniana (1.0–4.8 %), Mucor spp. (1.5–12 %), Penicillium spp. (0.5–1.5 %), and Aspergillus spp. (1–1.5 %) on the seeds. The trend to decrease laboratory germination and lower infection rate was observed after the seeds were treated with biofungicides Gaubsin, Planriz, and Trichodermin. The positive effect of the biofungicides on the morphometric parameters of two-weeks-old plants was observed: 1.6 to 2 times increase in height, 2.1 to 2.8 times increase in the lengths of the roots, and 2.7 to 4.4 and 3.4 to 5.5 times increase in phytomass, respectively. The positive effect of Trichodermin on developing winter wheat plants was noted.
