Background and objective:
Brazil became one of the largest consumers of pesticides in the world at the beginning of the 21st century. The production model based on the Green Revolution has as one of its highlights the abusive use of pesticides with severe impacts on human health and ecosystems. This study presents results of research on Popular Surveillance of pesticides in three regions of Brazil: South, Midwest and Northeast.

Methods:
It is an action research based on Paulo Freires ideas and Ecology of Knowledge by Boaventura Santos. The research was carried out in 2022 in the states of Rio Grande do Sul, Mato Grosso and Ceará, in territories with vulnerable populations such as peasants and quilombolas. The territories were visited by the team of researchers and workshops were held to analyze the problems of each location and collectively produce action plans for each territory.

Results:
The communities identified some qualitative indicators of Popular Surveillance, highlighting the following indicators of threat to life: the death of bees, groundwater with the odor of pesticides, animals with congenital malformations, plant mortality and families sprayed with pesticides from airplanes. On the other hand, life promotion indicators were identified such as agroecological productive backyards, organic production areas and collective organizations for monitoring the territory.

Conclusion:
The Popular Surveillance of Pesticides is marked by popular protagonism in the defense of life and its development can contribute to the strengthening of institutional surveillance.
