In the conditions of the Republic of Belarus there were presented the data on the efficiency of a preparation Strazh, SC (epoxyconazole 187 g/l + thiofanat-methyl, 310 g/l) Frandesa Company Ltd. for sugar beet (Beta vulgaris var. saccharifera) and spring wheat (Triticum aestivum) protection against the main diseases. The most effective periods of application and optimum application rates of the fungicide Strazh, SC for sugar beet protection against cercosporosis (Cercospora beticola Sacc.), powdery mildew (Erysiphe communis grev.) and spring wheat against Septorial leaf spot disease (Septoria spp.) and head blight (Fusarium spp. are generalized. The research confirmed the high biological and economic efficacy of the fungicide Strazh, SC in crops of sugar beet and spring wheat. It was found that the use of the fungicide during the growing season of sugar beet at a rate of 0.5 l / ha reduced development cercosporosis 4-5 times, and as compared with the control there was obtained biological yield of 72 kg / ha, with improved technological properties of roots. The fungicide Strazh, SC in dose 0.6 l / ha in spring wheat showed high fungicidal activity against Septoria and Fusarium head blight and provided relative to the control yield increase of 4.6 t / ha. On the basis of research results, fungicide Strazh, SC (epoxyconazole, 187 g / l + thiophanate -methyl , 310 g / l) in a rate of 0.5 l / ha , was included into the 'State Register' for use in crops of sugar beet against cercosporosis and mildew, and at a rate of 0.6 t / ha - in spring wheat against Septoria and Fusarium head blight.
