The use of silicon compounds to increase the resistance of spring barley to diseases and reduce pesticide load in dry steppe of the Lower Volga region

Slastya I. V.  (Сandidate of Agricultural Sciences, Associate Professor, Russian State Agrarian University – K.A. Timiryazev Moscow Agricultural Academy)

The effect of silicon compounds (seed- and foliar-applied) in organic (TPP) and inorganic (sodium silicate) forms on spring barley diseases in a small-scale field experiment was studied. It was established that application of silicon compounds alone and in the mixture with a reduced rate of fungicide promoted a reduction of diseases of barley varieties Kamyshinsky 23, Donetsky 8, Prairie. The efficiency of silicon compounds depended on weather condition of the growing season, type of application and the response of the varieties. In dry years the use of reduced fungicide rate together with silicon compounds was more effective on all varieties.

Keywords:silicon compounds, fungicide ferrax, seed treatment, foliar application, diseases of barley, drought
