REACTION OF SPECIES X. VESICATORIA AND X. EUVESICATORIA TO COPPER PRODUCTS

Katya Vasileva

Abstract


The relationship of the selected strains of the genus Xanthomonas to different concentrations of copper sulfate, copper oxychloride and copper hydroxide was investigated. Diversity among strains was observed in terms of their susceptibility to the tested products. It was found that as the concentration of copper products increased, so did the sensitivity of the bacteria. However, strains differ from each other in their sensitivity to your concentration. The data show that the strains isolated from tomato are more sensitive to the tested substances compared to the strains isolated from pepper. The percentage distribution at the lowest concentration (0.1%) shows that copper sulfate is the most effective against the bacterial strains 62%, while the remaining two products are weakly expressed. The concentration of 0.2% in copper products has the following content: 44% copper sulfate, 41% copper oxychloride, 15% copper hydroxide. The percentage distribution at the average concentration shows that copper sulfate again prevails at 41%. No significant differences were found between the products at high concentrations of 0.4% and 0.5%.
