Cultivation of peach (Prunus persica (L.) Batsch) is the fourth agricultural row of Pamplona province; however, research results on plant pathology issues are scarce. The objective of this research was to evaluate the influence DAP (Days after Pruning) on the seasonal dynamics of main diseases of the peach tree in the municipality of Cacota. Plots with three pruning moments of the "Gran Jarillo" cultivar were selected to evaluate the incidence percentage, severity and the AUDPC (Area under the Disease Progress Curve) of the main foliage and fruit diseases. Plots were evaluated for an 11-months period, considering the farm environmental conditions. At the end of the production cycle, a statistical analysis of mean comparison was performed for unrelated samples according to the Z test (p <0.05) for each variable. Statistix (V4) and SPSS 23 statistical software were used. Results showed that Taphrina deformans affects mainly leaves and Sphaerotheca pannosa fruits. T. deformans is evident from the moment the first leaves unfold and reached its maximum incidence between 57 and 99 DDP for pruning in November and March, respectively. S. pannosa obtained its highest incidence (98.76%) at 166 DDP in November; for this same treatment Monilinia fructicola reached its highest incidence at 260 DDP and only affected fruits in a ripen state.
