Description
The growth-regulating activity of naphthalenesulfonylamide and pyrazolopyridines derivatives was studied under laboratory and field tests on tomato plants. We have found substances with high growth-regulating effect. The vegetative mass of plants, the number of ovaries in the hand, the size of the fruit, the yield and the sugar content of the fruits increased under the influence of the growth regulators

DEVELOPMENT OF NEW SOYBEAN GROWTH REGULATORS
DescriptionTo develop new promising soybean growth regulators, we have synthesized series of derivatives of nitrogen-containing heterocycles. Synthesized compounds have been studied as potential soybean growth regulators. Substances with a high growth stimulating effect have been found. The growth regulators affected the branching coefficient, the number of seeds in the beans and their weight. The yield increased by 6.7-23.4%, the quality of grain increased

06.00.00 Agricultural sciences
DescriptionIntensification of agriculture during the twentieth century was accompanied by an increase in international trade, resulting in the resettlement of many species across continents. As a result of these processes, many adventives species have become economically significant and dangerous plants in agro and urban biosensors. One such plant is Ambrosia artemisiifolia L., imported from North America to Russia. The use of chemical means of suppression of A. artemisiifolia L. often does not give positive results in agrocenoses, because of its biomorphological features. In urban areas, within the boundaries of sanitary zones, the use of chemicals is prohibited. Therefore, the most promising direction in the suppression of ragweed ambrosia is the ecologies method. The article discusses the possibility of using an ambrosia leaf beetle in the feeding of ragweed in the territory of Russia

BIOLOGICAL CONTROL OF THE APPLE MOTH NUMBER BASED ON ENTOMOPATHOGENIC VIRUSES (REVIEW)
DescriptionThe article considers the data on the applicability of bioinsecticides based on the granulovirus as an active ingredient against the apple moth. The methods for producing strains of the Cydia pomonella granulovirus to develop bioinsecticides are explained. The methods for the reproduction of laboratory populations of insects, the method of their infection and isolation of viral onset are described. The stages of obtaining bioinsecticides in vitro, as well as methods for their storage are provided

IMPROVEMENT OF AGROTECHNOLOGICAL METHODS IN A FRUIT TREE NURSERY
DescriptionAgro-technological operations, achieved in the specialized fruit tree nurseries are directed toward the optimization of the seedlings cultivation conditions. The agro-chemicals application is one of the most important technological questions in production system. The method of the complex use of physiologically active materials with the nourishing salts is directed, in the first place, toward the development of the healthy, actively functioning assimilation apparatus of the perennial plant, whose task – the balanced increase and the formation of reproductive organs already in the early stages of ontogenesis. In the article the results of work on introduction into the flow chart of the production of the apple tree landing material of bio stimulants and fertilizers of the directional effect are represented. Positive effect from the introduction into the diagram of nourishing salts of stamp N20P8K8+1,5Mg+9S in different combinations with the preparations: «lignogumat» of sodium, «lignogumat» of potassium, by ethane-1,2-dicarboxylic acid, by the natural stimulator of an increase «Silk» it was reflected in the level of the plants security of with mineral elements, it contributed to an increase on 5,7-10,2 % the diameter of trunk; the height of seedlings exceeded index in the control on 4,9-6,2 %

THE SEARCH FOR NEW SUGAR BEET IMMUNOMODULATORS AMOND PYRIDYLHYDRAZONE DERIVATIVES
06.00.00 Agricultural sciences
DescriptionIn order to find compounds that increase sugar beet resistance to the adverse effects of herbicides, a series of pyridylhydrazone derivatives have been synthesized. The protective effect of new compounds for the herbicide mixture Betanal, Lontrel and Super Zeleke was studied in field conditions. The effect of pyridylhydrazones on the synthesis of photosynthetic pigments in leaves was investigated. Substances with a high protective effect were found

TECHNOLOGY OF POWDERED FOOD ADDITIVES
DescriptionIn recent years, the problem of deficiency of biologically active substances in a number of food products has arisen. This is due to a deterioration in the quality of seed and planting material and, accordingly, a decrease in the content of BAS in the cultivated fruit and vegetable raw materials. In this regard, processing companies are forced to fill the lack of vitamins and dyes with synthetic components. The aim of the research is to obtain concentrated food additives from domestic plant raw materials. To achieve this goal, the tasks of obtaining powders from fruits and berries are solved with maximum preservation of BAS of the raw material during drying. High-quality powders from fruits and berries are obtained by cryogenic technology, using liquid nitrogen at one or several stages of the process. As intermediate results of the research, the paper presents materials on the dispersion composition of cryopowders and the solubility of their various fractions in aqueous media. The technology of obtaining and using powdered food additives from fruits and berries, ground in liquid nitrogen, has been approved. The comparative characteristics of the composition cryopowders from apricot, sea-buckthorn, pumpkin, feijoa and persimmon are given. The results of the studies confirmed the expediency of using cryopowders from fruits and berries to enrich various food products

NEW GROWTH REGULATORS AND ANTIDOTES FOR ENVIRONMENT-FRIENDLY PLANT PROTECTION
06.00.00 Agricultural sciences
DescriptionSearching for new promising plant growth regulators and antidotes, we have synthesized a series of Nsubstituted naphthalene-2-sulfonylamides. Synthesized compounds have been studied as potential growth regulators of economically significant crops - winter wheat, sugar beet, sunflower, soybean, and herbicide antidotes for sunflower growing plants. The substances with high growth stimulating and antidote effect were found
