The article reviews the results of the study of the
influence of lignohumates of the grade "A" («LG-
АМ», «LG-А super BIO», «LG-А super L») on the
grape vines treatment of the Saperavi variety on the
quality must and wine in the Anapо- Taman zone of
the Krasnodar region. The technology of the
cultivation of grapes on the experimental plot
corresponded to the adopted in the JSC "Victory" of
Temryuk District, and was accepted for keeping of
fruit-bearing plantations area of non-covered
viticulture. Agrobiological works were carried out at
the optimum time and were of high quality type. Vines
of the third year of life, embodied by the scheme in 3,0
x 1,5 m. The forming was a one-sided Guyot with a
height of 60 cm in trunk. There was formed the same
load by shoots and clusters on the shoots. The
treatment of leaf surface bushes with the solutions of
lignohumates were conducted twice: 1st - before
flowering and 2 nd at the beginning of the formation of
berries (20 days after the first one). The spraying was
carried out in the early morning hours. The accounting
for the grape harvest and sampling to determine the
quality of must and wine (10 kg each variant) was
conducted in September 20, 2012. Technological and
physical-chemical analyzes were carried out in the
shop micro winemaking and accredited testing
laboratory of grape processing of the SSI NCZSRIHV
of RAAS. Preparations "LG-B Bio", "LG-B Super
Bio" and "LG-B Super A" as grape plant growth
regulators have equal and stable effect
The article investigates the impact of waste of elevators on morphological parameters and productivity of winter wheat grown on black leached soil
In the present article the main research results of
investigation of the means of pre-milking and postmilking
treatment of cow udder and dugs are presented.
The treatment of cow udder dugs produces great effect
on the milk quality, the incidence level of mastitis of
cows in the herd, extension and pathogenic agents
transmission from sick to healthy animals; and also
udder treatment provides hygienic protection of udder
dugs. Tree concentrations of detergent of chloride
dioxide were tested. Whereof, dilution of detergent with
concentration of 90 mg/l chloride dioxide proved
effective disinfective effect in pre-milking treatment of
udder dugs. The developed medication for post-milking
treatment of cow udder dugs presented high preventive
efficiency against mastitis and provided longer hygienic
protection of cow udder dugs after milking
The article gives the results of the three years of
research to identify the main species composition of
fungal pathogens when stratified open and closed
methods. Biological efficiency of Guapsin, 0,2%, and
Trichodermin, 0,5% is shown. During the period of
stratification, using an open method "on the water", the
following pathogens have evolved: Cladosporium
herbarum (18,6%), Trichotecium roseum (16,3%),
Phomopsis viticola (13,9%), Alternaria spp. (13,4%),
Penicillium sp. ( 9,1%), Aspergillus sp. (5,6%),
Pythium sp. (4,3%), Gonatobotrys flava (4,3%),
Mycelia sterilia (2,8%), Botrytis cinerea (2,2%). The
studies found that the close method of stratification in
the peat developed the following specific composition
of pathogens: Penicillium spp. (21,1%), Phomopsis
viticola (16,4%), Botrytis cinerea (15,3%),
Trichotecium roseum (11,1%), Alternaria spp. (8,2%),
Mycelia sterilia (1,0%). During the period of
stratification, biological efficiency Guapsin, 0.2%, and
Trichodermin, 0,5%, was 31,9-88,0% and 28,2-86,3%,
respectively
Universal black-berry Apollo grape has been launched in Greece by P.Zamanidi, L.Troshin and A.Isachkin in 2003 with combinative selection - crossing of the Fi-lery Greek variety with the French Cabernet-Sauvignon. The duration of the production period 136-145 days. The strength of growth of arms is strong (2,1-3,0 m), the degree of maturation of the vines is high. Crop yields are very high - 35-40 t/ha. The aver-age mass of clusters is 430 g. It is characterized by high winter hardiness, drought-resistance and high resistance to fungal diseases in comparison with varie-ties of Vitis vinifera. The flower is bisexual. Cluster is big or very big, conical with the wing, loose. Berries are medium or large, oval, blue-black in color, with a thick wax coating. The skin is thick. The pulp and juice - with varietal flavor. Sugar content is high. Notable for long saving the harvest in the bushes, well-kept in the cooler cells. The variety is meant for the fresh consumption and for manufacture of red dry, desert and sweet wines; suitable for production of high-quality juices
To develop the novel herbicide antidotes for the
sunflower vegetative plants, the group of chemical
compounds, belonging to the derivatives of 2-
alkylthionicotinonitrile was synthesized and their
antidote activity both in the laboratory and field
experiments was studied. The compounds with a high
antidote effect were found
In this article, an anthropogenic influence on natural
ecosystem such as an excavation of sand is discussed.
Investigations were done in Kuyar Forest District of
the Mari El Republic on a sandpit. The adjacent plot
of natural forest was taken as a control. For evaluation
the degree of environment transformation as a result of
sand excavation several indicators were used. As
indicators of physical soil degradation - thickness of
organogenic horizon and soil density; for assessment a
chemical degradation – content of main nutrients and
humus; as an indicator of biological degradation – the
level of active microbial biomass. Besides, a potential
phytotoxicity was estimated. The study proved:
physical and chemical parameters corresponded with
the fourth degree of soil degradation, at the same time,
biological parameters approximated to parameters of
soil from natural territory
The anthers of glutinous rice variety Violetta (1400) have been grown in medium N6 producing 72 calluses. Transplanting the calluses to regeneration medium MS gave 7 green fertile plants and one sterile. After 10 months the long cultivated calluses of the glutinous rice Violetta produced regenerated plants. They were passed onto MS medium containing 5 mg/l 6-benzylaminopurine and 1 mg/l IAA. Clonal reproduction was used for production of more haploid regenerated plants
The exchange experiments results have proved that in terms of aflatoxicose risk the best indicators of the digestion were revealed for the broiler chickens of the native cross “Smena-4” and foreign “Ross 308” using the toxi-nyl admixtures
For the research period (2003-2016), 57 pest species
and 46 pathogens were recorded on stone and
pomaceous fruits in humid Russian subtropics,
among which the representatives of the order
Lepidoptera and the division Ascomycota
predominate. The greatest number of the species was
recorded on the apple tree - 35 pests and 25
pathogens, the smallest - on cherry and sweet cherry
trees (13 and 10, respectively). 43,7 per cent of the
species are polyphages, while the relative abundance
of monophages among fungi is higher than among
arthropods. The species with activity in the summer
are prevalent. A group of species that are harmful in
humid subtropical environments all year round (11
species of phytophages and 19 pathogens) was
identified. Analyzing the changes in the species
composition of the complex through the time, we can
speak about the relative stability of the dominant
species. The group of the typical dominant species of
pests for almost a century has included Grapholita
molesta Busck., G. funebrana Tr., Cydia pomonella
L., Taphrina deformans (Berk.) Tul., Stigmina
carpophila (Lév.) M.B. Ellis, Monilinia laxa (Aderh.
et Ruhland) Honey, M. fructigena Honey,
Podosphaera leucotricha (Ellis & Everh.) E.S.
Salmon, Venturia carpophila E.E. Fisher and pear
V. pyrina Aderh. Eriosoma lanigerum Hausm.,
Scolytus mali Bechst. and Tranzschelia prunispinosae
(Pers.) Dietel are currently dropped out
from the group of the dominants; Halyomorpha halys
Stål, which is a new pest for Russia, was added.
Groups of the species with sharp fluctuations in
abundance or frequently encountered were
distinguished
