In the conditions of the Republic of Belarus there were presented results, obtained under production and field trial conditions on biological, economic and economical evaluation of the developed bulb onion (Allium сера) crop protection system (modern assortment of insecticides, fungicides and herbicides) against the noxious organisms. Long-term studies on the efficacy of preparations of different spectrum allowed us to develop a system of measures to protect the onions from pests, diseases and weeds. The proposed protection system allows to decrease onion fly larvae damage for 90,5%, onion downy mildew - for 50,9%, weed infestation -for 54.3% and get 76 cwt/ha bulb onion in addition with the profitability - 137.9%. The use of the system to made it possible to reduce the potential harmfulness of phytophagous, pathogens and weeds to economically imperceptible level, improve the economic efficiency of phytosanitary measures to preserve the harvest and get products with high quality.
