In this research a survey was conducted in an orchard of apple in order to assess the possible spread of the disease apple proliferation (AP) in the Sierra de Arteaga. The importance of this disease lies i the reports of the presence of species of the Rosaceae family, which includes the apple and cherry tree, which was where the symptoms were observed, therefore directed sampling on trees latter located in performed limits orchard used as biological barrier visual survey for observing characteristic symptoms was performed. Parallel has evaluated the incidence of the disease in the orchard by visual inspection of 200 trees. In September, the incidence was 0.5% and the capulín the species concerned We assessed the expression of disease symptoms AP throughout the year by obtaining a 40% severity in infected trees but it is not excluded that this phytoplasma is present in asymptomatic trees.
