Abstract

The business practice carried out in the company Jarillos el Puerto S.A.S located in the municipality of Cácota-Norte de Santander, focused on the development of an integrated management (IM) of brown rot (M. fructicola) in the peach crop (P. persica), due to the fact that this disease is of great economic importance in deciduous fruit crops, since this pathology affects susceptible states of the plant such as the moment of flowering and ripening of the fruit where percentages of (I) and ( S) greater than 80% causing great losses in crop production and profitability. The main objective of the practice was to determine the I and S of the disease and likewise design a manual focused on the MI of brown rot within the company; The methodology specifically proposed for the measurement of I and S began with the selection of 5 lots for study, in each lot 20 plants were chosen randomly, later the tree was evaluated taking as sampling units 4 branches distributed in each cardinal point, where 5 fruits were taken as a reference for observation, in order to obtain a total of 20 fruits per plant and a total of 400 sampling fruits for each lot, and in this way obtain quantitative data from each lot in order to establish percentages of I and S. The results obtained show that the disease only appeared during the harvest moment when the fruit is more susceptible, data were obtained in which it could be concluded that the percentages of I and S were less than 10% clarifying that climatic conditions are the most relevant item at the time of spread of the fungus, as well as the time of pruning the tree.
