Abstract: Barley is a valuable food crop, which is known for its lack of resistant to the effects of root rot. In this context is an urgent problem in agriculture to the search the preparations and the methods of their usage to prevent yield losses from pests. In this article, the author describes the new preparation of fungitoxic influence — alkamon OS-2, PS and the methods of its usage. The preparation under study alkamon OS-2, PS used in knitting and textile industries as a softener and an antistatic. The author examines the possibility of using the preparation as a tool to protect the crops of barley from the development and the spread of root rot. The article assesses the effectiveness of experimental preparation on a background of traditionally used the preparation fungitoxic influence albite, TPN in the territory of Russian Federation. The author gives an impact comparison of the methods of using two preparations on barley yields and its affection root rots. The article provides data on the influence preparations on incidence of root rot brewing barley on different organs-receptors. These researches reveal the prospects of using experimental preparation as a tool for barley protection. Alkamon OS-2, PS effectively prevents the development of root rot throughout the season and, in some cases, it is even more effective than preparation albite, TPS. The preparation alkamon OS-2, PS demonstrates the biological effectiveness of 36 to 54 % in different phases of development of barley. Different combination methods, using experimental preparation, provide an increase to the yield from 0.45 to 0.98 t/ha and the economic efficiency is achieved at the rate of 26 %.
