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

Description
The present work describes the chemical synthesis of poly-N,N-diallyl pyrrolidinium bromide and polyN,N-diallyl morpholinium bromide - high-molecular compounds containing quaternary nitrogen atoms, which included in two five- and/or six-membered heterocyclic rings. These polymers are perspective modifiers for industrially produced anion-exchange membranes, the use of which should significantly improve the resistance to degradation of the membranes at over-limiting current regimes. The structure of obtained polymers was characterized by FTIR, 1H and 13C NMR spectroscopy. The optimal reaction conditions, which increase the yield of desired products, were defined. It is shown that is preferable to use 1-butanol as a solvent and benzoyl peroxide as an initiator

CAYENNE, NEW HERBICIDE FOR FIGHTING WEEDS IN CROPS OF WINTER WHEAT
06.00.00 Agricultural sciences
DescriptionOne of the most destabilizing factors of crop production is weed infestation of crops. Despite annual herbicide treatment, weed infestation of crops of winter wheat remains high, with a predominance of annual dicotyledonous weed with a higher proportion of drug resistant on the basis of 2,4-D. We also notice increased range and density of perennial dicotyledonous weeds. New combinational herbicide called Cayenne, manufactured by LLC "Agro Expert group", which in its composition contains two active substances: thifensulfuron-methyl (500 g/l) and florasulam (170 g/l), highly inhibits both annual and perennial dicotyledonous weeds. According to the working program of the registrant's company we have tested Cayenne on crops of winter wheat in spring in the tillering phase and the formation of the second internode. It is shown that its use in doses of 0.025 and 0.035 kg/ha in mixture with 200 ml/ha of surfactant-Bit 90, W provides effective suppression of annual and perennial dicotyledonous weeds (90 – 100 %). The negative effect on the culture was not observed. At the same time, within 2-3 days after herbicide application we observed cessation of growth, chlorosis, dieback of growing points of weeds. Complete death was observed after 15 – 20 days

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

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

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

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 %
