In this sense, the aim of this work is to establish the operators’ level of knowledge regarding the operational safety, as well as the use and management of pesticides. In order to do this, information acquired through a questionnaire applied to 56 operators of agricultural sprayers from two Brazilian regions, West and Central Frontier of the state of Rio Grande do Sul, was used.
