Polischuk S. Bacterial diseases of soybeanin conditions of forest-steppe of Ukraine and substantiation of measures on restriction their development

Subject of research - bacterial diseases of soybean in Forest-Steppe of Ukraine, harmfulness and specific composition of their agents. Objective of research- to explore bacterial diseases of soybean and to ground environmentally benign ways of their development limitation according to current growing technologies. Methods of research - laboratory, field, weighing, morphological-physiological, statistical. System of ways of soybean protection from bacterial diseases is scientifically substantiated, symptoms of seed-lobe bacteriosis, angular spotting and pustular bacteriosis are described, specific composition, spreading and harmfulness of soybean bacteriosises agents are specified, growing conditions influence on diseases development and sowing material quality is shown and those which confine their development are found, varieties with genetical fastened stability to angular spotting and pustular bacteriosis are selected, advantage of using biological preparations comparing to their chemical analogues are found . System of soybean protection from diseases based on optimization of sowing terms, fertilizing system and choosing the precursor is improved which ensures favourable phyto-sanitary condition of crops. Scientific researches during 2007-2010 are implanted on Panfylska research station of NRC "Institute of Agriculture of the NAAS", Yahotyn district Kyiv region on the area of 340 hectares. Field of using - agricultural production.
