Yashuk V. Agroecological substantiation of Biopolitsydu and Ecotones in growing and storing onions.

In the dissertation is experimentally proved and soundly of treatment expediency of the onion (seedling onion) seeds by biologicals Biopolitsyd and by chemicals Ecoton, thus it is reducing the plants infestation by peronosporoz, contributes to the intensity of plants metabolic processes, increases the yield and quality of the resulting product, increases the proportion of healthy follicles after winter storage, reducing the need for the use of hazardous pesticides. The yield of onion in the 2010-2012 period (field studies) ranged 20,5-22,5 tons per hectare, which is 10,12 % higher than in the control variant. Treatment of onions seed by Biopolitsyd promotes marketability of the crop, which is 22% higher than in the control variant and Ecotone -23%. The economic efficiency of the preparations Biopolitsyd and Ecoton was calculated and determined, that the product profitability of variant with using a biologicals was at 130-140 %. We proved, that the preparations Biopolitsyd and Ecoton are environmentally friendly in agronomically reasonable quantities, because it does not have an eco-toxic effect on the functioning of soil microorganisms and soil mesofauna. Results of studies in determination of their biological, ecological, economic efficiency were used in the registration by the Ministry of Ecology and Natural Resources of Ukraine as environmentally friendly.
