Species composition of oats diseases in the Right-bank Forest-steppe of Ukraine has been clarified. Results of application of biological fungicides by the method of seed dressing and surface treatment for the protection of tunicate (Chernihivskyi 28 variety) and hull-less (Samuel variety) oats are provided.

At present, one of the main tasks is to obtain high-quality and environmentally friendly phyto-products. The interest of consumers in healthy nutrition is increasing every year. Growing plant products using organic technology is becoming widespread. Among a wide range of economic management, organic agricultural production is the only environmentally friendly method on Earth that does not inflict damage on the environment. Organic production systems are based on specific and precise requirements (standards) for the production process aimed at maintaining the optimal state of the ecosystem at the social, environmental and economic levels. The level of plant damage is controlled naturally, as well as with the help of preventive, biological and other modern scientific methods. Organic agricultural production excludes the use of artificial fertilizers and pesticides, as well as genetically modified organisms and products (substances) derived from them. The developed system for the protection of winter spelt against fungal diseases under organic production is based on biological features of mycoses, introduction of varieties with the least degree of affection by pathogens of fungal etiology, application of optimal systems of soil tilling and fertilizing, sowing time and seed application rates, as well as rational use of effective mixtures of biological preparations and plant growth regulators for seed and crop treatment. Organic protection system involves the following: complex treatment of seeds with biological preparation Agat 25-K, PA (0.04 kg/t) and plant growth regulator Biosyl (0.01 l/t) before sowing; spraying of crops at the 31st stage with a mixture of Agat 25-K, PA (0.03 kg/ha) + Biosyl (0.01 l/ha); the same treatment of crops at the 39th stage; spraying of crops with biological preparation Phytodoctor (2.0 l/ha) at the 60th stage. Under organic production, the winter spelt yield preserved due to a set of protective measures amounts to 0.58-0.67 t/ha or 29.6-33.7%. At the same time, the protein content increases by 0.83% and gluten content by 6.9%.

The results of monitoring the development and spread of disease in oats forestrysteppes of Ukraine in the early stages of organogenesis.
