In Colombia, farmers have used chemical pesticides that have caused damage to the soil and to their own health. This has produced risks and conflicts of ethical origin regarding the use of such products, since farmers are often unaware of their harmful effects, while manufacturers are aware of them (Espluga Trenc, 2001). In this scenario, this article deals with the identification of conflicts from an ethical perspective, by means of ethical principles, such as the cardinal principles of Ricardo Maliandi; the principle of justice of Beauchamp and Childress, as a way of deepening the universality principle; the principle of autonomy of Beauchamp and Childress, which deepens the principle of individualization; the precautionary principle, which explains the principle of conservation; and the principle of responsibility, which in turn is materialized in the realization principle. By means of the connections between the cardinal points and their own specifications, the conflicts generated by the use of pesticides in the country can be identified and addressed in order to reduce the damage to the soil and the health of the farmers who work it.
