Title: Bacterium complexes Pseudomonas fluorescens and matters of stimulating nature impact on potato development
Abstract: The bacterium strain AP-33 Pseudomonas fluorenscens was the researches subject. The derivatives of ammonium salts of dihydropirymidine did not show toxic action on concentration decrease of viable cells of bacterium strain AP-33 Pseudomonas fluorescens. All biocomplexes combinations showed preparations efficiency against diseases in the scope 59,31-69,63 %. The best yield on potatoes was shown by the combination of AP-33 strain of Pseudomonas fluorescens bacteria, 3x109 CFU/cm3-5 l/ha+0.1% ximedon solution+0.2% succinic acid solution+2 ml of DMAE+2 ml of DMSO, which amounted to 3,4 t/ha. The combination ’s efficiency against late blight consisted of 79,1 %.
