The paper studies the influence of biological preparation Ekstraflor 8 on the ability of strawberry to form runners. When growing seedlings of strawberry ecological production plays an important role. Studies of 10 varieties of strawberry have showed that the ability to form runners depends on the particular variety, as well as the use of a biological product. Zenith and Maryshka strawberry varieties formed the largest number of runners. Biological preparation Ekstraflor 8 contributed to an increase in the number of runners in the varieties Zenit, Tsariza, Tsarskoye Selo. Application of Ekstraflor 8 led to an increase in leaf area, plant height and number of runners. Almost all varieties of strawberry marked an increase in the seedlings due to the use of biological preparation Ekstraflor 8. The greatest number of commodity seedling varieties showed Zenit, Marshmallow, Koupchikha, Maryshka. The remaining varieties inferior to the performance, but also increased the use of biological preparation results. In comparison with micro fertilizer Ryazanochka biological preparation Ekstraflor 8 has greater efficiency in output of marketable sprouts.
