It is shown that aqueous extracts from bird cherry tree Padus avium L., aspen Populus tremula L., and celandine Chelidonium
majus L., effectivily suppress the germination of Puccinia triticina Eriks uredospores. Fungitoxic activity of
the extracts is supposed to be determined by high content of phenolic compounds and high peroxidase activity in the
leaves of these plants. Fungitoxic activity of the extracts from the leaves, inflorescences, roots, and stems of siberian
cowparsnip Heracleum sibiricum L., was also correlated with the content of phenolic compounds in these organs. Treatment
of healthy wheat Triticum aestivum L., cv. Lyubava, with the extracts from common comfrey Symphytum officinale
L., cowparsnip Heracleum sibiricum L., and giant knotweed Reynoutria sashalinensis (F. Schmitt) Nakai, stimulated the
photosynthetic activity in treated leaves.
