The data are presented on the economic justification of the use of new technology of ULV with forced deposition of droplets of dispersed working fluid on the treated surface in comparison with the traditional technology of LV in the protection of crops from weeds. The use of ULV technology has resulted in a high biological efficiency of treatments and 25 % decrease in norms of entering herbicides that has a great importance in ecological safety of pesticides in addition to economic significance. As a result of twenty-fold reduction of the working fluid flow rate, the necessity of using the water supply unit was eliminated and the organization of work was improved, which allowed reducing the cost of plant protection by 27.72 %, by 62.45 % depreciation and amortization of technical facilities, by 18.2 % the costs of labour and by 92 % water for working solutions.
