Abstract
- Two types of the grain field pathogen complex formation are selected in dependence of the meteorological conditions of the Steppe Zone of Ukraine. First type is characterized with stress situations (drought, high temperatures) and facultative pathogens predominance. Second type is connected with precipitations abundance and obligate parasites occurrence. Threatens impact on winter wheat seeds germination and affection with root rots were studied in the field experiments. Two ecological factors (air temperature and aphids) are main reasons to the beginning of potato seeds degeneration processes. Ensuring sustainable crops yield productivity is impossible without ecological farming as following: varieties resistance to disease and insects, biological control preparations, rational use of organic and composts and use of microbiological products with multiple effects.
