“…Safer alternatives to chemicals are currently available, including inorganic, organic and biological controls [14]. Currently, numerous studies are being conducted in the field of biological protection of plants that would not have a negative impact on the environment and would not contain dangerous chemicals [15,16]. There are a large number of plants that have antimicrobial agents and antioxidants in their composition [17].…”

The Vitis vinifera L. cultural grape includes many varieties that are highly valued in winemaking and viticulture, as raw materials for the production of fresh and dried berries, for the production of wines. The fruits of cultural grapes play an important role in medicine, where they are used as a source of substances with high antioxidant activity. Grapes are often affected by phytopathogenic fungal infections. In recent years, a large number of reports have appeared in the literature about the acquisition of resistance of microorganisms to industrial pesticide preparations, which in turn leads to an increase in drug doses, the multiplicity of treatments and the accumulation of harmful substances in the environment and in the plants themselves. In this study, we evaluate the effectiveness of the fungicidal action of industrial preparations and plant extracts in relation to two native species of fungi (V1 and V2) isolated from the leaves of cultivated Vitis vinifera L. grapes, as well as against the phytopathogen Alternaria solani K-100054. Minimal inhibitory (MIC) and fungicidal concentrations (MFC) were detected for each sample. Ethanol extracts of plants showed low antimycotic activity in relation to fungi cultures isolated from grapes. Activity started from 0.0625%. The best result among industrial fungicides was shown by the drug “Maxim”, whose MIC values was 0.097 μg/mL, and the MFC varies between 3.125-12.5 μg/mL for pathogens V1 and V2, respectively.

“…Today we can say with confidence that phythotherapy entered its Renaissance. This reveals in increasing interest to ethnobotany and in use of biologically active compounds extracting from plants as alternative for synthetic chemical drugs due to their high effectiveness, economic profitability, ecological and biological safety [5][6].…”

Toxic action of substances from male fern Dryopteris filix-mas (L.) Schott (1834) on free-living soil nematode Caenorhabditis elegans Maupas (1900)

The study of biological activity of extracts from roots and rhizomes of male fern Dryopteris filix-mas was carried out in experiments with soil nematode Caenorhabditis elegans. The toxicity of extracts of D. filix-mas roots and rhizomes obtained by different methods varied over a wide range. Crude extract of male fern roots and rhizomes in concentration range 62.5–250 µg/ml had a weak toxic action on C. elegans organism by inducing death of 26.0–43.3% nematodes. The toxicity of relatively high concentrations (500 and 250 µg/ml) of water-ethanolic extracts might be compared with such of crude extract in concentrations 62.5–250 µg/ml. Biological activity of filicinic acids ethers was found very high: concentrations of crude extract of D. filix-mas roots and rhizomes and concentrations of filicinic acids ethers with similar toxicity for C. elegans organism were 40-fold different. Substances isolated from D. filix-mas roots and rhizomes have nematicidal activity and may be used for development of drugs to treat helminthiasis of humans and animals.

Potassium Salts of Terpene Acids of Siberian Pine Resin as Effective Drug in the Cultivation of Potatoes in Organic Farming

et al. 2020

Siberian pine is a source of a wide range of biologically active substances for use as biopesticides and growth stimulators in organic farming. Ten components, among which the share of abietic acid reached 54.8%, have been determined with the help of the gas chromatography/mass spectrometry method. Water-soluble potassium salts of terpene acids were obtained from Siberian pine resin during the work. Potassium salts of terpene acids from Siberian pine resin has bacteriostatic, fungistatic, bactericidal, and fungicidal properties against phytopathogens. Relatively high indicators of antioxidant activity of aqueous solutions of potassium salts from resin at 1 mg/mL were revealed. Pre-planting treatment of tubers with an aqueous solution of terpene acids salts of Siberian pine resin in a concentration of 10 g/L contributed to an increase in the yield of potato. Also, an increase in the mass fraction of dry matter and starch was also observed.
