Survive: the great challenge throughout the centuries. Food was considered the restrictive law of man since the earth was not able to produce all the necessary food. Meanwhile, wars have bloomed a new model of agriculture based on mechanization, on the use of fertilizers and agrochemicals, and on extension. However, it brought risks to the farmer's health. The purpose of this study is to draw a parallel between the extension, its reflexes and the challenges regarding the education of the farmer about the dangers of the use of agrochemicals in a market society. Taken from secondary data, it was observed that the classic model of extension fulfilled its role by diffusing a productive model to the capitalist model. In addition to neoliberal policies, this process limits extension services in Brazil, increasing the dangers to the farmer's health and the chances of biomagnification.
