In this paper we used the technique of X-ray fluorescence by dispersion in energy in order to study a phytopathology named “sooty mould” in olive tree leaves in the Mediterranean area. Samples studied included leaves which were infected and non-infected by sooty mould. Energy depressive X-ray fluorescence showed a significant increase in the amount of Fe in the affected leaves when compared to leaves that don't have this pattern of black material. We suggest here that a treatment for this condition may be based on a method that deprives these organisms of the Fe that they apparently need to survive. The average Fe concentration obtained for the infected olive tree leaves was 80 ppm, while the non-infected ones showed no measurable Fe presence.

Abstract
In this paper we used the technique of X-ray fluorescence by dispersion in energy in order to study a phytopathology named “sooty mould” in olive tree leaves in the Mediterranean area. Samples studied included leaves which were infected and non-infected by sooty mould. Energy depressive X-ray fluorescence showed a significant increase in the amount of Fe in the affected leaves when compared to leaves that don't have this pattern of black material. We suggest here that a treatment for this condition may be based on a method that deprives these organisms of the Fe that they apparently need to survive. The average Fe concentration obtained for the infected olive tree leaves was 80 ppm, while the non-infected ones showed no measurable Fe presence.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
