Abstract The article presents the results of the investigation of efficiency of modern protectants for the limitation of the spreading of powdery mildew and septoriosis in the Eastern part Steppe-Forest of Ukraine. The purpose of the experiments is to study the efficiency of the protectants, their effect on crops quality, biological indicators of seed and spring wheat seedling, as well as the influence the limitations of the development of diseases fungal etiology. The results of our research have revealed that except the protective effect of protectants in the struggle with seed infection, they also increase laboratory germination and stimulate the growth of seedlings, as a result - plants have well-developed root system. The obtained results of studies of the efficiency of protectants in the protection from powdery mildew and septoriosis show, that highest efficiency has been noted in protectant fungicide Sertikor FS 050 (93.3%) for wheat sort Spadschina. Technical efficiency Selest- Top 312 FS in all variants of experiment ranged from 41,5-76,7% and the FS Maxim Star 025 - 32,1-83,3%.
