Study Regarding Effectiveness of Some Plant Extracts and Different Pesticides against an Erwinia Amylovora (Burrill.) Winslow et al. Strain Isolated from Quince The interest in management fire blight prevention and control increased considerably in last years due to pathogen spread almost throughout the country. The objective of this paper focuses on testing of some plant extracts such as Salvia officinalis, Thymus serpyllum, Pelargonium odoratissimum, Hedera helix, Ocimum basilicum, Levisticum officinale, Tagetes patula, Galium verum and different pesticides against an Erwinia amylovora strain isolated from quince dameged samples. In this study, the biological material was represented by quince shoots, harvested from pomological collection of "Vasile Adamachi" farm, which belongs to University of Agricultural Science and Veterinary Medicine Iaşi. The research were performed in the Phytopathology laboratory. Following the experiment performed note that among the eight plant extracts a good antibacterial activity has Pelargonium odoratissimum, Ocimum basilicum and Salvia officinalis and of the three pesticides, Alcupral 50 PU. Contrary to expectations worst results were obtained after testing Aliette 80 WG and Hedera helix products. The results were estimated statisticaly, by performing ANOVA test. Studiu privind eficacitatea unor extracte din plante şi pesticide asupra unei suşe de Erwinia amylovora (Burrill.) Winslow et al., izolata de pe gutui Interesul pentru managementul prevenirii şi combaterii focului bacterian al rozaceelor a crescut considerabil în ultimii ani, ca urmare a răspândirii patogenului pe aproape întreg teritoriul ţării noastre. Obiectivul acestei lucrări are în vedere testarea unor extracte din plante precum Salvia officinalis, Thymus serpyllum, Pelargonium odoratissimum, Hedera helix, Ocimum basilicum, Levisticum officinale, Tagetes patula, Galium verum şi a unor molecule active, asupra unei suşe de Erwinia amylovora, izolată din lăstarii de gutui, ce prezentau simptome tipice atacului de foc bacterian. Materialul luat în studiu a fost recoltat din ferma "Vasile Adamachi" din cadrul Universităţii de Ştiinţe Agricole şi Medicină Veterinară Iaşi, iar cercetările s-au efectuat în laboratorul de cercetare al disciplinei de Fitopatologie. În urma experimetului efectuat se observă că, dintre cele opt extracte de plante, cea mai bună activitate antibacteriană o prezintă Pelargonium odoratissimum, Ocimum basilicum şi Salvia officinalis, iar dintre cele trei pesticide, Alcupral 50 PU. Contrar aşteptărilor, cele mai slabe rezultate s-au obţinut în urma testării produselor Aliette 80 WG şi Hedera helix. Rezultatele au fost interpretate statistic, folosind testul ANOVA.
