The reasons for the broad distribution of Erigeron annuus in Central Russia (its biology (habitat, seed productivity, seed distribution) and its ability to exert allelopathic influence) are discussed. The following indicators were used in the experiments to assess the effect of Erigeron annuus on other species: seed germination, development rate, and length of the hypocotyl. The seeds of Erigeron annuus were found to inhibit the development of seedlings in a number of species (Trifolium pratense, Raphanus sativus, and Avena sativa). The majority of the experiments clarifying the effect of Erigeron annuus were performed on Trifolium pratense.
