There is a growing interest in agriculture to replace synthetic chemicals with natural plant products that may have a bactericidal action. we have chosen two plant species to test their antibacterial effect against Xanthomonas fragariae Dw on tomato plants of the variety campbell 33, inoculated with this strain and two extracts pretreated with different concentrations (1%, 3% and 5%) are prepared from the leaves and stems of each species. We tested the one hand, the effect of these extracts on the removal or reduction of Xanthomonas fragariae Dw to the surface of the seeds, and secondly, their effects on growth parameters inoculated tomato plants. The effect of treatment of tomato seeds by the three concentrations of aqueous extracts of Rosmarinus officinalis L has given us a significant reduction compared to treatment with the extracts of Chenopodium ambrosioides L. Analysis of variance at the 5% threshold showed that six treatment plant extracts induced significant responses with degrees variants on vegetative and root biomass as well as the axial growth.

Abstract: (french)
Il y a un intérêt croissant dans l'agriculture pour remplacer les produits chimiques synthétiques par des produits naturels d'origine végétale qui peuvent avoir une action bactéricide. nous avons choisie deux espèces végétales pour tester leurs effet antibactérien contre Xanthomonas fragariae Dw, sur des plants de tomate de la variété campbell 33, inoculés par cette souche et prétraités par deux extraits de différentes concentrations (1%, 3% et 5%) qui sont préparés à partir des feuilles et tiges de chaque espèce. Nous avons testé, d'une part, l'effet de ces extraits sur la suppression ou la diminution de Xanthomonas fragariae Dw à la surface des graines, et d'autre part, leurs effets sur les paramètres de croissance des plants de tomate inoculés. L'effet des traitements des graines de tomate par les trois concentrations des extraits aqueux de Rosmarinus officinalis L nous a donné une réduction importante par rapport aux traitements par les extraits de Chenopodium ambrosioides L. L'analyse de la variance au seuil de 5% a montré que les six traitements des extraits de plantes induisaient des réponses significatives avec des degrés variantes, sur la biomasse végétative et racinaire, ainsi que la croissance axiale.
