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

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

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

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

Description
The research work was conducted on the tomato hybrid F1 Мо 755 × L. esculentum var racemigerum (Lange) Brezh. The individual characteristics of the reproductive system of tomato F1 hybrid were studied for their further inclusion into the selection programs. The dynamics of these factors in regard to the clusters in the tomato inflorescence was investigated.

DescriptionUsing two microsatellite loci (HaSSR1, HaSSR3), the PCR analysis of the bollworm Krasnodar population was conducted. Molecular-genetic analysis (SSR-PCR) of different geographic codling moth populations by three microsatellite loci Ср1.63; Ср2.39 и Ср2.157 was conducted also. Based on the assessment of the frequencies of occurrence of DNA markers, the molecular-genetic structure was described and genetic diversity in the pest populations was estimated
