The aim of the present study was to evaluate the influence of different extracts (water, ethanol, enzymatic) from germinated seeds of spring barley on the development of Pseudomonas putida bacteria. The tests on optical density were performed to study the influence of different extracts on the development of model extracts. The analysis of the influence of different extracts from germinated seeds of spring barley on biological agent - Pseudomonas putida PCL1760, contained in biopreparations for crop protection showed that ethanol extract from Raushan variety of spring barley increased the resistance of Pseudomonas putida PCL1760 to the heat and osmotic stresses. All the types of extracts did not contribute to the increase of bacteria resistance to low temperatures. There was no significant difference established between the activity of spring barley extracts with vernalization and without vernalization. The materials of the study showed that ethanol extracts from spring barley can be used for the development of Pseudomonas spp. based on biopreparations for the enhancement of biocontrol microorganisms (BCMs) activity.
