Leaf treatment of Liberty apple plants by preparation Regalis reduced of germ shattering that contributed increasing of yield and improving of fruit quality. Treatments by growth regulator Atonik Plus in stressful conditions of summer period prevented fruit abscission and improved their quality, quadruple treatment by this preparation increased apple yield. The yield surplus on 5,1 t/ha for account of increasing of fruit average weight is obtained by 3 times treatment of preparation Reasil Universal

The method of a field experiment accompanied with laboratory analyses and mathematical data processing is the basis for work. At a laying of a field experiment and carrying out calculations and observations and other types of field works used the standard techniques are used. The analysis of the obtained experimental data is carried out by methods of mathematical statistics. The biological assessment of growth regulators of new generation in the plantings of fruit and berry crops and grapes was the purpose of our research. The research was conducted in the plantings of an apple-tree, wild strawberry and grapes. The regulators of growth of new generation - Atonik Plus, Zerebra Agro, VL 77, Agro-Stimul and Avibif on phases of plants development of plants during the vegetative period were used. The results of the conducted research showed that a 3-time processing by Atonik Plus in a dose of 0,2 l/hectare, was the most effective on an apple-tree, the reliable increase in a crop of fruits was 7,0 t/hectare in comparison with control. The increase in a crop of fruits is occurred due to a smaller falling of fruits during formation of an ovary and increase in average mass of fruits. On Elsanta strawberry use of the Avibif growth regulator promoted the improvement of growth processes of plants, the increase in quantity of flowers was observed. The increase in berries crop was 2,5 t/hectare of with a dose of preparation of 0,6 l/hectare. The greatest rise of a crop is got at processing of grapes by preparation VL 77 in a dose of 0,3 l/hectare (6,5 t/hectare). The research of biological efficiency of new forms of growth regulators in production plantings of garden cultures and grapes showed prospects their use for regulation of growth processes of plants, increases in efficiency and improvement of quality of fruits and berries.
