Abstract
In this study, the behavior of Xanthomonas fragariae, angular leaf spot of strawberry agent, was followed in the AB medium, enriched with nitrogen, phosphorus or with potassium, and in the soil of the Mamora forest with 14% to 28% of humidity in function of these fertilizer elements. The obtained results have shown that Na2HPO4 and NH4Cl, used, 0.01 and 0.05 mol/l, respectively as a phosphorus and nitrogen source, have a significant effect on the survival of Xanthomonas fragariae. By contrast, KCl, used as a source of Potassium, has no significant effect on the number of culturable cells.
