Abstract: The influence of Raskila bioorganic preparations on the productivity of conventional winter wheat 'Olivin', was investigated in order to stimulate and save synthetic herbicide Arrat and fungicide Tango Super for spring spraying. Scheme of research: 1. Control; 2. Winter wheat sprayed (BBCH 20-29) with Arrat 0.2 kg ha-1+Tango super 1.5 l ha-1; 3. Winter wheat sprayed (BBCH 20-29) with Arrat 0.2 kg ha-1+Tango super 1.5 l ha-1+Raskila 3.0 l ha-1; 4. Winter wheat sprayed (BBCH 20-29) with Arrat 0.1 kg ha-1+Tango super 0.75 l ha-1+Raskila 3.0 l ha-1. The best result in the period of 2014-2016 was received after application of the following combination in spring: Arrat + Tango super+Raskila. This combination allows to reduce the rate of pesticides in half (50%), the differences compared to control are significant, statistically reliable. A statistically significant increase in the following winter wheat ‘Olivin’ quality parameters was found: protein 13.1-14.8%, gluten 24.3-29.7%, number of falls 228-292 s, starch 65.7-70.0%. Application of Raskila fertilizers has raised the grain quality class. The best results were in variants 3 and 4, where the I class of grain quality was achieved. Combination of Raskila fertilisers and pesticides: herbicide Arrat and fungicide Tango super statistically significantly increased the following winter wheat 'Olivin' characteristics - plant length 101,22-104,23 cm, penis length 6,86-7,14 cm, grains in ear 28,96- 30.02, grain yield 6.71-7.03 t ha-1. Application of Raskila fertilizer 1.0 l ha-1 and herbicide Arrat 0.1 kg ha-1 decreased the number of weeds from 62.5 to 57.6 units per m2 and the weed weight decreased from 41.30 to 33.70 g m2. Stronger wheat crop overshadowed weeds better. Combination of Raskila and Tango super reduced the prevalence and severity of diseases in winter wheat such as Septoria spp., Pyrenophora tritici-repentis, Erysiphe graminis, powdery rust (Puccinia recondita)
