The mechanisms of transmission of potato viruses from plants to aphid vectors and from aphids to uninfected plants are described, including the example of the green peach aphid (Myzus persicae, GPA). Factors affecting the spreading of tuber necrosis and its manifestation on plants infected with potato leafroll virus (PLRV) are discussed. Recommendations for PLRV and GPA control in the field are given.

The article considers the issues of the influence of the main tillage on the yield of crops of grain-tilled crop rotation: vetch-oat mixture - winter wheat - potatoes - barley. It was found that in addition to the reception of soil cultivation, the productivity of agrocenoses was also influenced by meteorological conditions.

The results of the influence of the mass of planting tubers of Jerusalem artichoke on the size and fractional composition of the crop of tubers in the conditions of sod-podzolic sandy loam soils during autumn planting of tubers are presented. It was found that planting tubers weighing 80-100 g g provide a yield of 45 t/ha. With an increase in the mass of planting tubers, the cost of purchasing planting material increases sharply and profitability decreases. Planting small tubers leads to a decrease in yield.

In a competitive variety trial, promising selection lines of sugar sorghum were studied in the Lower Volga region. Based on a set of signs, the best lines were identified, which are recommended for transfer to the State Variety Testing. Breeding lines, which are distinguished by high values of commercially valuable traits, can be used in planned crosses to create highly productive varieties and hybrids of sugar sorghum.

Based on the analysis of the intraspecific structure of the fungus Zimoseptoria. tritici, it was found that this species has significant polymorphism. Using monogenic wheat lines (Oasis (Stb1), Veranopolis (Stb2), Israel (Stb3), Tadinia (Stb4), CS / Synthetic (Stb5), Estanzuela Federal (Stb7)), the population of Z. tritici in the Central Black Earth region was tested. High heterogeneity of monosporous isolates of Z. tritici by virulence was revealed.

In conditions of climate change, when temperature and precipitation fluctuations occur more and more frequently during the growing season, it is necessary to obtain high quality seedlings with "immunity" to various stress factors, including high weediness, the damage from which is associated with a decrease in yield (by 25 -35%) and with a deterioration in the quality of agricultural products. Due to the imbalance in production technology, seedlings are often weakened, overgrown, with a low yield per unit area and survival rate in the field. One of the solutions to this problem is the use of PP for pre-sowing seed treatment to increase the competitiveness of seedlings in the field.

Medicago has a high nutrient content, and the aerial part of Medicago lupulina contains saponins, tannins, estrogenic substances and calcium salts. The leaves of this plant contain carotene, vitamin D and ascorbic acid. Medicago lupulina can develop a significant green mass, has low pubescence, thin stems and provides a delicate forage. The article presents the results of assessing the productivity and feeding qualities of new varieties ofMedicago lupulina
