Senecio vulgaris L. is a weed, considered difficult to control, when it is associated with carrot, because it competes for resources with the crop, its control being important, since it has a negative impact on crop productivity. Biological modeling is a tool that allows predicting the possible effects of the species control, since it identifies the different variables of a system and the factors that affect them, in order to predict the results in different environments. Based on the dynamics of systems and the morphophysiological aspects of the species, the modeling of the S. vulgaris seed bank was suggested, based on the equations proposed by Fernández-Quintanilla, the Forrester diagram was constructed, which was incorporated the different equations and values of the model, to project the dynamics of the species in the seed bank, depending on the management. Three scenarios were proposed, (1) post-emergence herbicide control, (2) crop rotation (3) incorporate traditional control methods with a control in presowing and crop rotation. The model results show that when crop rotation is performed and pre-sowing management is incorporated into the conventional process of the species, a smaller quantity of seeds is presented in the bank.
