“…Heavy rain is often followed by high relative humidity, creating good conditions for the disease, but rain can also wash away spores (Merchan and Kranz 1986). The relationship between a disease scoring scale and yield loss is not straightforward that climatic elements influence disease indices and yield loss correlated (Jevtic et al 2017).…”

S TRIPE rust infection caused by Pucciniastrii formis f. sp. tritici was investigated in ten Egyptian wheat cultivars under field conditions during two seasons (2016/17 and 2017/18) at two locations (Sakha and Sids) differ climatologically in Egypt. Variable levels of rust infection followed by a significant reduction in grain weight were recorded at both locations. Stripe rust infections for Sids location (20S-90S) were higher than those of Sakha location (TrMS-70S). Average coefficient of infection (ACI) and grain weight loss for Sids location, reaching 90 ACI (Gemmeiza-11) and 23.12% (Giza-160), were higher than those of Sakha location up to 70 ACI and 16.72% in Giza-160. Grain weight loss was strongly associated with ACI among cultivars for both locations, recording r=0.9044 for Sakha location and r=0.8866 for Sids location. Climatic variations were recorded at both locations during the first four months of 2017 and 2018. Rainfall and relative humidity for Sakha location were higher than those of Sids location while wind speed for Sids location was higher than that of Sakha location. Temperatures were relatively close at both locations. ACI values for Sids location were higher than those of Sakha location, revealing correlation with climatic factors. This suggests that wind speed may play an important role in dispersal while relatively heavy rainfall may have opposing effects. The temperature was the main limiting factor for stripe rust infection (negatively associated), followed by relative humidity (positively associated). Our discovery represents a powerful tool for predicting disease infection and management.

The peculiarities of ecology of certain types of pests breeding in field crops are highlighted. The indicators of the influence of a complex of factors on development and mass reproduction of insects under modern agricultural systems are generalized. The species composition of insect phytophages in new crops is specified. More than 20 species of pests were identified that severely damaged this crop according to the results of the monitoring of the wheat entomocomplex. The analysis of influence of temperature, air and soil on the trophic links of phytophages and development and survival of their stages was conducted. A close connection between the level of productivity and the stages of organogenesis of plants with separate stages of development of the main species of phytophages was established. The analysis of efficiency of application of modern monitoring of a complex of pests at new systems of protection of winter wheat has been carried out. Cereal flies, aphids and other pests are found are found on wheat. The basic ecological and biological peculiarities of the formation of the entomocomplex of winter wheat are determined. The peculiarity of monitoring and control of harmful insect species on winter wheat crops in the forest-steppe of Ukraine is highlighted. The analysis of the modeling efficiency of the number of harmful and useful insect for resource-saving systems of winter wheat protection is carried out. The peculiarities of biology and ecology of pests of stem and of the root system of winter wheat in the region of research are specified. The peculiarities of the formation of entomocomplexes in agrocenoses vary according to certain parameters, in particular the number of soil and interstitial phytophages, taking into account the radius of their daily displacement. It is relevant to determine the total demand of pests in feeding at the actual population of individuals at different stages of ontogenesis of grain crops for effective crop management. The application of resource saving models of the calculation of phytophage dynamics on cereal crops by hydrothermal coefficient at different periods of development of plants and phytophages in the production, which allows to determine the quantitative changes of a separate entomocomplex in grain crops in time and space. The development and introduction of integrated methods for the control of winter wheat pests according to modern agricultural systems in the forest-steppe of Ukraine, which determines the expected loss of grain in the crop fields becomes important.

5-15-40+МЕ). The liquid consumption was at a rate of 1000 l/ ha. Foliar fertilizing of pear trees of Osnovianska variety with DripFert complex fertilizer 18-18-18+МЕ (three time fertilizing during the growing season) provided a yield increase of 39.2 % and 13.6 % compared to the yield in absolute and production control variants. Variants with fertilizers provided an increase in the pear yield of the highest and first commercial grade (at 84.3-84.7 %).
