Influence of pruning moment of peach tree (Prunus persica L. Batsch) on dynamics of the main diseases

The cultivation of peach trees constitutes the fourth agricultural line of the province of Pamplona, Norte de Santander , Colombia however, they are the results of research on plant pathology issues. The objective of this research was to evaluate the influence of different pruning moments on the sea...

The cultivation of peach trees constitutes the fourth agricultural line of the province of Pamplona, Norte de Santander , Colombia however, they are the results of research on plant pathology issues. The objective of this research was to evaluate the influence of different pruning moments on the seasonal dynamics of the main diseases of the peach tree Prunus persica (L.) Batsch in the municipality of Cacota. To achieve this, plots were taken with three pruning moments of the Gran Jarillo cultivar, evaluating the incidence percentage, severity and the Area Under the Disease Progress Curve (ABCPE) of the main foliage and fruit diseases. The lots were evaluated for a period of 11 months, taking into account the environmental conditions of the farm. At the end of the production cycle for each variable, a statistical analysis of comparison of means was performed for unrelated samples according to the Z test (p <0.05). Statistix (V4) and SPSS 23 statistical packages were used. As a result, it was shown that Taphrina deformans mainly affects the leaves and Sphaerotheca pannosa the fruits. The first 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 pruning in November, for this same treatment Monilinia fructicola reached its highest incidence at 260 DDP and only affected fruits in a ripe state.https://revistas.unicordoba.edu.co/index.php/temasagrarios/article/view/1862/2730gran jarillotaphrina deformanssphaerotheca pannosamonilinia fructicola
