RESISTANCE OF WINTER WHEAT CULTIVARS TO YELLOW LEAF SPOT PATHOGEN
06.00.00 Agricultural sciences
DescriptionThe results of immunological assessment of winter wheat varieties included in the State register of breeding achievements of the Russian Federation and the variety of different types of resistance to yellow leaf spot pathogen are presented in this article

SEEDS AS A SOURCE OF SUNFLOWER PHOMOPSIS SPREAD
06.00.00 Agricultural sciences
DescriptionThe ability of Phomopsis to transmit from affected seeds to plants has been studied in both anamorphic and teleomorphic phases of its development in the year of sowing. The sunflower lesion with Phomopsis affects not only the germination, but also causes the plant disease

NEUTRALIZATION OF HERBICIDE NEGATIVE IMPACT ON SUGAR BEET WITH BIOSTIMULATORS
06.00.00 Agricultural sciences
DescriptionMost modern chemicals designed to protect crop also actually cause negative effects on the protected plants mostly due to side effects and/or not following the application procedures correctly. It is possible to neutralize the negative effects of herbicides they have on cultivated plants with precise use of immunostimulants which will increase the plants' natural immunity against the negative effects of biotic and abiotic environmental factors

Description
The analysis of the variability dynamics of recombination frequency in the population of splitting F2 interspecific and intraspecific tomato hybrids has been carries out. It was discovered that recombination frequency depends on the components of cross breeding. It has been established that it is reasonable to use mutant forms of Мо 393, Мо 628 and interspecific hybrid F1 Мо 628 × L. esculentum var. racemigerum in selection process as an inductor of genotypic variability

BARLEY LEAF RUST (PUCCINIA HORDEI OTTH. PATHOGEN) IN THE NORTH CAUCASUS: SPREAD AND RASE COMPOSITION
DescriptionThe spread of barley dwarf rust pathogen has been studied in five agro-climatic zones of North Caucasus in 2012-2013. The race composition of the North Caucasian pathogen population was identified

SYNTHESIS OF SUBSTITUTED PYRIDINE- 3-SULFONYL ISOCYANATES AND PYRIDINE- 3-SULFONYL UREAS
DescriptionAcylation of amides substituted with pyridine-3- sulfonic acids oxalil-chlorides and phosgene was studied. New pyridil-3-sulfonil isocyanates were synthesized. The conditions for this synthesis were optimized by taking into account the detailed understanding of this acylation. The synthesized pyridine-3-sulfonyl isozyanates were converted to pyridine-3-sulfonyl ureas. Biological activity of the new compounds was studied and the substances with high herbicidal effect were found

EFFICIENCY OF CHEMICAL FUNGICIDES AGAINST LEAF TAN SPOT OF WHEAT
06.00.00 Agricultural sciences
DescriptionIn recent years leaf tan spot had dominated into pathogenic complex of wheat in southern Russia. The causative agent of this disease is hemibiotrophic ascomycete Pyrenophora tritici-repentis (Died.) Drechsler; imperfect state of Drechslera triticirepentis (Died) Shoem. It causes two different symptoms in susceptible wheat varieties: chlorosis and necrosis. Under epiphytotic disease progression crop losses can achieve 65%. One of the most important elements of phytosanitary control of wheat cenosis is scientifically relevant chemical fungicides application. Biological efficiency of some fungicides against Pyrenophora tritici-repentis has been estimated. Research was conducted on the experimental ground of FSBSI ARRIBPP on the variety susceptible to the pathogen – Krasnodarskaya 99. Preparations were tested one time at leaf-tube formation (Z37) phase or two times: at leaf-tube formation (Z37) and start of heading (Z51) stages. Double treatment was more effective than a single one. Fungicides “Amistar extra” and “Prozaro” have got the high biological efficiency – 80,7 and 83,7%, consequently, and longer protective period (up to 40 days) in comparison to every tested fungicides

NEW GROWTH REGULATORS OF THE WINTER WHEAT
06.00.00 Agricultural sciences
DescriptionSome derivatives of 3-aminothieno[2,3-b]pyridines, N-pyrazolo[3,4-b]pyridinil-3-carboxamides and substituted naphthalene-2-sulfonic amides were synthesized for the search of the new winter wheat growth regulators. The growth regulating activity of the new compounds was studied and the substances with high growth stimulating effect were found

Description
Due to the wide spread of winter barley varieties with different Phytopathologic characteristics, a serious threat to the crop is dwarf rust caused by a pathogenic fungi of the Puccinia. The article presents the results of phytosanitary studies conducted in different agroclimatic zones of the North Caucasus region for the period from 2013 to 2015. Electronic maps of levels of development and distribution of dwarf rust are based on phytosanitary inspection. On the experimental field called «Kuban» as well as rust nursery of VNIIBZR we have performed an immunological evaluation of the sustainability of winter barley accessions to the pathogen of the dwarf rust on natural and artificial infectious backgrounds in the period from 2013 to 2015. The article reflects the objective characteristics of varieties and lines of winter barley with a relative stability to the North Caucasian population Puccinia hordei. The most promising varieties and lines of winter barley of the KubGAU breeding were selected during operation. These varieties and lines are highly resistant to rust and dwarf, they also have other valuable features. The article presents information on the best yield varieties and lines of winter barley as well as on gross yield and sowing area

METHODS OF DESTROYING COMMON RAGWEED IN SUNFLOWER CROPS IN THE KRASNODAR REGION
06.00.00 Agricultural sciences
DescriptionRagweed plant became quarantine malware on the territory of Southern Russia. In the Krasnodar region it has been extended to the territory of more than 4.62 million hectares. In the areas of its growth, it causes great damage to agriculture. By developing a strong root system and aboveground, it inhibits the row crops, especially sunflower. Another problem with this weed is producing large amounts of pollen that causes allergic reactions in the majority of residents of the province. This article discusses the importance of using modern methods of ragweed oppression, including chemical and biological methods in sunflower crops
