The rhubarb root, leaves and inflorescence extracts are a source of various bioactive substances. As part of the chemical raw materials from Rheum rhaponticum, 3 basic bioactive substances, that are promising for the creation of plant protection products, can be identified - emodin (pesticide, antifidant, bactericide, fungicide), quercetin (antifidant for flying insects, pesticide, bactericide, antiviral, aldose-reductase inhibitor) and oxalic acid (antiseptic, activator). The action of R. rhaponticum extracts on the Aphididae family pests was determined. Insecticidal activity of rhubarb leaves extract against aphids (57.8%) allows using it in environmental protection of plants in combination with insecticides, in order to reduce the number of chemical treatments. |
