Essay

In conditions of the East Forest Steppe and Steppe of Ukraine in 1982-2004, expansion, intensity and damage threat of Pseudopeziza medicaginis (Lib.) Sace, Pseudopeziza jonesii Nann, Peronospora aestivalis Syd., Uromyces striatus Schrot. and Erysiphe communis Irev. have been investigated. Biological peculiarities of pathogens development, relations with alfalfa phenology and weather conditions have been made more precise. Models for short-term and long-term prediction of alfalfa diseases' expansion and intensity have been developed. Their indirect relation with solar activity dynamics has been proved. Differentiated 7-mark immunological scale has been created, 12 pathotypes of Uromyces striatus Schrot. have been identified. Group resistance of perspective sorts of alfalfa to fungal diseases that are valuable source for breeding has been estimated. The role of agrotechnical measures in alfalfa diseases control has been determined. System of seed alfalfa growing and protection has been developed and implemented in Kharkov, Donetsk, Dnepropetrovsk and Zaporozhje regions of Ukraine.
