The problem which has to be solved consists in the enlargement of biologically active elements, ecologically safe, with stimulating effect on the bees growth, which will improve the effectiveness of top dressing usage in the process of the bee colony encrease, quantity of the sealed brood and their productivity. The goal of the work is the study of the natural bioregulator “Verbascozid” usage influence on the spring top dressing on the development and productivity of bee colonies. The natural bioregulator usage during spring top dressing without supportive honey gathering stimulates development of bee colonies efficacy on 40,19%, mated queens’ fertility – on 4,65-4,86%, honey production  - on 46,46% more in comparison with the control group. Optimal dose of natural bioregulator (“Verbascozid”) is 60 mg/l of sugar syrup, and this process takes place during all the spring period, from the first days of April till the beginning of white acacia honey gathering, one liter per one bee colony once in 6 days.
