BURKHOLDERIA CARYOPHYLLI-POTENTIALLY DANGEROUS PATIENT OF BACTERIAL WITNESS IN FLORISTRY OF UKRAINE

Abstract

To determine the harmfulness of the causative agent of bacterial wilt Burkholderia caryophylli for floriculture in Ukraine, to analyze the possibility and ways of getting this pathogen into our country. In preparing the article, general scientific methods were used: generalization, comparison, system analysis. The material for the analytical study was the data of the European and Mediterranean Plant Protection Organizations (EOPR), as well as data from the phytosanitary services of the EU and Ukraine, scientific literature. B. caryophylli causes bacterial wilt or bacterial cracking of stems on carnations, eustoma and pottery. This is a fairly heat- and cold-resistant bacterium (capable of actively infecting plants in the temperature range 17-33˚C) and can infect and stay in both the philosphere and rhizosphere of the plant. Cells are straight or slightly curved rods with rounded ends, single or paired cells. Aerobic, does not form disputes. Cells are motile with one or more flagella, gram negative. Oxidase-positive, do not form indole, H2S. Restores nitrates. Ferment glucose, inositol, argenin, xylose, ribose, rhamnose, sudan, dilute gelatin, do not hydrolyze starch. The main methods of research and identification are: visual, cultural-morphological and biochemical methods, IF, enzyme-linked immunosorbent assay and BOX-PCR. To date, there are no effective pesticides to kill B. caryophylli, so the only possible way to stop the spread of bacterial wilt is to remove and destroy infected plants, as well as to comply with phytosanitary measures. Thus, the causative agent of bacterial wilt of the carnation B. caryophylli is a quarantine object of the A-1 list in Ukraine and A-2 in the European and Mediterranean Plant Quarantine and Protection Organization. When imported into our country has a high probability of acclimatization and spread in floriculture in Ukraine
