Antimicrobial effect by citric extract on <em>Ralstonia solanacearum</em> and on <em>Xanthomonas axonopodis</em> pv. <em>manihotis</em>
Abstract
The widespread application of agrotoxics to control crop diseases has caused human and environmental contamination problems and also a selection of resistant pathogens to these chemical products. Thus, the aim of this work was, by means of citric extract, (Ecolife40 commercial product), to assess the antibacterial activity. The effect of concentrations of 1, 10, 100, 1000 and 5000 ppm of citric extract was carried out on bacteria Ralstonia solanacearum and Xanthomonas axonopodis pv. manihotis through observation of the following parameters: inhibition zone, optical density and colony-forming units. Through the obtained results, it was verified that citric extract showed antibacterial activities. The antibacterial activity was dosis-dependent, and it is more efficient at 5000 ppm.Downloads
