Abstract :
Electron microscope investigations have revealed disintegration of the cell wall of Pseudomonas syringae pv. atrofaciens and subsequent killing of bacterial cells after application of 1% solutions of the citrates of Ag-Cu nanoparticles, the complex Co-Cu-Zn-Fe-Mn-Mo-Mg (Avatar-1) and iodine-selenium. In field conditions, it was revealed that pre-sowing treatment of wheat seeds with the aforementioned 1% solutions significantly inhibited the development of basal glume rot in cereals with artificial infection of Pseudomonas syringae рv. аtrofaciens. Consequently, reduction of the typical symptoms of basal glume rot of cereals and the percentage of isolated cells of Pseudomonas syringae рv. аtrofaciens D13 were detected in wheat plants upon pre-sowing treatment of wheat seeds by experimental biocides. These results can be explained by structural changes in the bacterial cells of the pathogen that lead to reduction of viable forms of bacteria due to damage of both the cell wall and internal contents.
