In 2016, 2017 studies on the influence of fungicides on the development of diseases on the leaf surface of carrots were carried out. To study were taken fungicides Akanto Plus, Signum, fast and Rex duo. The research was carried out on the varieties of carrots of the Primorskyaya 22 and Taiphun. The work was carried out at the seaside vegetable Experimental Station – branch of the federal State budget scientific institution "Federal Scientific Center of vegetable growing" in coastal zone of Primorsky Krai in conditions of monsoon climate with annual quantity Precipitation 700-800 mm, most of which falls on the summer period. Natural climatic factors of Primorsky Krai create the most favorable conditions for development of high infectious background of pathogenic flora. The leaves of carrots here are amazed fitopatogenami from childbirth Alternaria, Cercospora, Xanthomonas. Diseases appear in the sowing of carrots usually in the second half of the growing season, after clamping tops in rows. The first treatment of drugs was carried out at the appearance of the first signs of disease on the leaf surface of the carrot, two subsequent treatments-in 14-16 days, depending on weather conditions. The most biological efficacy after three treatment showed the fungicide Signum: 53.2% on the variety of Primorskyaya 22 and 54.3% on the grade Taiphun, which contributed to the highest yield of carrots in this variant. The increase in the yield of standard root crops was here 10.0 t/ha or 41.0% on the grade of the Primorskyaya 22 and 7.6 t/ha or 28.4% on the grade Taiphun compared to the control version.

Garlic is one of the most ancient plants which the person turned to himself on advantage. The larger need for production of garlic for consumption and as raw materials for manufacture of medicinal preparations and, at last, just for use by the population as remedy for many diseases and for the preventive purposes led to the fact that bulk production of garlic in the world makes 24,836 million tons, and the area under garlic reached 1,465 million hectares. n Russia the area under garlic on all categories of farms is 28,4 thousand hectares, and production – 256,406 thousand tons. From factors influencing on the increase production of garlic, one of basic is a sort. Selection of garlic includes improvement of local grades, creation new high-yield, steady against diseases and to wreckers of grades, with the increased content of sugars, essential oils and biologically the active materials. Results of long-term researches by laboratory selection of onions cultures (VNIISSOK) on studying, assessment and selection exemplars grades of garlic winter, collected from different regions of Russia and the CIS countries, on a complex of signs are presented in article (winter hardiness, efficiency, to quality of production, resistance to wreckers and diseases).

It is important to reveal the genetic base of breeding genetic material used for development of new breeding accessions among diverse Brassica oleracea L. (CC, 2n = 18). Traditional varieties, hybrids and new ones recently developed are the main genetic resources.Classification of a collection with DNA markers enables to reveal valuable genotypes and establish the breeding accession pedigree that allows developing the new accessions with sustainable economically valuable traits. The use of microsatellite markers (SSR) in B.oleracea L. has shown high efficiency in discovering genetic polymorphism between varieties and within varieties as well. In this study, 16 primer pairs have been taken to amplify microsatellite loci of genomic DNA in national 24 breeding accessions of cabbage. On the basis of the data obtained the dendrogram has been constructed with use of Jaccard’s coefficient. All locistudied were high informative, where 14 out of 16 had a PIC > 0.5. As a result, the level of genetic polymorphism has reached 85.7%. The large cluster of head cabbages consists of three subclusters: mid-maturing and early-maturing accessions of white head cabbage, red head and savoy cabbages, late-maturing and midmaturing accessions of white head cabbage, respectively. Maximum genetic distance in the cluster of head cabbages was obtained between head cabbage ‘Slava 231’ and ‘Vertu 1340’ with genetic similarity 44.7%. The two varieties of red head cabbage ‘Gako 741’ and ‘Kamennaya Golovka 447’ were genetically similar at 71.1%. The relatively low genetic similarity of these varieties can be explained by that they belong to different varietal groups. The most genetically closest varieties were ‘Zimovka 1474’ and ‘Podarok‘ with genetic similarity 86,5%. Information on topologic differentiation obtained from cluster analysis can be the basis for selection of genetically valuable breeding material with the use of DNA markers (Marker Assisted Selection).

Vegetable growing is one of the most dynamically developing branches of agriculture in the Russian Federation. Research on the economics and organization of the production of vegetables and fruits of melons and gourds began at the All-Russian Scientific Research Institute of Hydrometeorology (VNIIO) after its formation in 1930 and served as the basis for the creation of commercial vegetable-growing zones, specialized farms and green-house complexes around major cities and industrial centers of Russia, as well as vegetable farms in other republics. The following were developed: a promising scheme for the development and placement of vegetable growing in zones of the country in open and protected ground, scientifically based proposals for improving the organization and increasing the efficiency of vegetable growing in Moscow, Ryazan, Ivanovo, Bryansk, Irkutsk, Lipetsk and other regions of Russia. From 2000 to 2014, research focused on the development of concepts for the development of commercial vegetable and seed production of open and protected soil in the context of existing economic relations and forms of management. Since 2015, an analysis of the economic efficiency of vegetable production in the Russian Federation has been carried out, taking into account large-scale and small-scale production, interregional exchange of vegetable products, taking into account import and export, equivalence of inter-sectoral exchange, development of cooperation in the village, economic efficiency of long-term storage of fresh vegetables, and optimal size of vegetable production. for vegetable producers of all forms of ownership, safety of vegetable products in the context of food safety Russia. Today, Russia produces 105.7 kg of vegetables per capita per year, and in 2017, the self-sufficiency of open and protected soil in vegetables was 81.1%. The large stability of large-scale production was noted in the conditions of the unfavorable economic situation in the vegetable industry. Identified systemic problems that limit the increase in the production of vegetable products and adversely affect its effectiveness.

Effects of humic preparation (HP) Stimulife and PGPR (plant growth promotion rhizobacteria) Bacillus subtilis №2 on the productivity and quality of the sweet pepper (Capsicum annuum L.) fruits were studied in the control conditions. It was experimentally established that the use of Stimulife and bacteria Bacillus subtilis №2 resulted in an increase in plant height, productivity and biochemical composition of sweet peppers. Differences in the effect of the studied preparations on the morphometric, phenological and biochemical characteristics of plants and fruits of pepper varieties Ermak and Cinderella were revealed. The bacteria Bacillus subtilis №2 significantly increased the yield, the number of fruits per one plant and the contents of ascorbic acid and carbohydrates in pepper fruits. In this case, the average weight of one fruit of pepper v. Ermak decreased. HP Stimulife increased the pepper yield due to increasing the mean mass of one fruit in both pepper varieties. Joint used of HP Stimulife and bacteria Bacillus subtilis №2 led to an intensification of the production process of plants compared to the experiment variants, in which HP Stimulife was used alone. The yield of sweet pepper Ermak and Cinderella increased by 10-45%, the maturation period of fruits was reduced by 10-14 days, the content of ascorbic acid increased by 25%, sugar content increased to 26%. The expediency of the joint application of HP Stimulife and bacteria Bacillus subtilis №2 in the cultivation of sweet pepper under controlled conditions is substantiated.

In terms of occupied areas, onion is on the third place in the world among vegetable crops, second only to tomato and watermelon. In Russia, onion is grown on an area of 88 to 96 thousand hectares of onions, and ranks third, yielding to cabbage and tomato.The increase in the production of onions is not only due to the increase in the areas occupied by the crop, but also due to increased yields. This is achieved by introducing new highly productive varieties and hybrids into production, increasing the overall cropping culture and the level of cultivation technology. Along with the creation of heterotic hybrids at the present time, the Russian Federation also continues to select varieties that show high rates when grown in a oneyear crop. The results of production tests of a new onion variety of Forward Selected Breeding VNIIO a branch of the FGBNU FNCO has shown that it is promising because it has a high yield potential, high quality of bulbs and excellent preservation in conditions of repositories with controlled conditions. Characterized by mid-maturity maturation. The period from full shoots to mass lodging of leaves is 110 days. In relation to the longitude of the day, the forward sort refers to a group of long-day bows. The bulb is bilobate, rounded and rounded – flat, with an average mass of 90-120 g. The color of the dry covering scales is yellow-brown, the succulent scales are greenish. The taste is semi-sharp. The dry matter content in the bulb during the test years was 11.0-12.0%.
