“…Oak wood is characterized by the presence of hydrolyzable tannins [52,57], whereas elder wood contains cyanogenic glycosides and lectins [59,60]. These compounds are moderately toxic to some decay fungi [61][62][63][64] and possibly altered the growth of R. solani in this study, which developed relatively small or thin mycelia on oak and elder sawdust, respectively.…”

“…Hence, wood chemistry likely influenced the composition and activity of decomposer fungi, which, in turn, may have determined the degree of disease suppression. Presence of fungistatic compounds in certain sawdusts may have selected tolerant decomposer species, and the release of such compounds by their decomposing activities may have contributed to inhibition of the growth of R. solani [64,[66][67][68]. This may explain why oak and elder sawdusts gave a high suppression of R. solani damping-off, although the increase of total fungal biomass by the sawdust was relatively low.…”

Impact of Cellulose-Rich Organic Soil Amendments on Growth Dynamics and Pathogenicity of Rhizoctonia solani

et al. 2021

Cellulose-rich amendments stimulate saprotrophic fungi in arable soils. This may increase competitive and antagonistic interactions with root-infecting pathogenic fungi, resulting in lower disease incidence. However, cellulose-rich amendments may also stimulate pathogenic fungi with saprotrophic abilities, thereby increasing plant disease severity. The current study explores these scenarios, with a focus on the pathogenic fungus Rhizoctonia solani. Saprotrophic growth of R. solani on cellulose-rich materials was tested in vitro. This confirmed paper pulp as a highly suitable substrate for R. solani, whereas its performance on wood sawdusts varied with tree species. In two pot experiments, the effects of amendment of R. solani-infected soil with cellulose-rich materials on performance of beetroot seedlings were tested. All deciduous sawdusts and paper pulp stimulated soil fungal biomass, but only oak, elder and beech sawdusts reduced damping-off of beetroot. Oak sawdust amendment gave a consistent stimulation of saprotrophic Sordariomycetes fungi and of seedling performance, independently of the time between amendment and sowing. In contrast, paper pulp caused a short-term increase in R. solani abundance, coinciding with increased disease severity for beet seedlings sown immediately after amendment. However, damping-off of beetroot was reduced if plants were sown two or four weeks after paper pulp amendment. Cellulolytic bacteria, including Cytophagaceae, responded to paper pulp during the first two weeks and may have counteracted further spread of R. solani. The results showed that fungus-stimulating, cellulose-rich amendments have potential to be used for suppression of R. solani. However, such amendments require a careful consideration of material choice and application strategy.

“…Due to a decrease in biodiversity of soil microflora and an increase in the anthropogenic load on the soil, fewer natural barriers to seed infection arise [1][2][3][4][5]. Therefore, seed treatment is an important technique in modern agricultural technologies for growing the majority of crops [6].…”

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.

The aim of the study was to study the biological activity of extracts of the aerial part and rhizomes with the roots of Echinacea purpurea (L.) Moench. Used laboratory and statistical methods. The activity of the extracts was studied by biotesting on the seeds of cress (Lepidium sativum), barley (Hordeum vulgare) and millet (Panicum miliaceum). It has been established that echinacea extracts affect a wide range of concentratins, plant phytomass increases and the sowing qualiies of seeds are stimulated. It is concluded that the further study of echinacea extracts is promising.
