Levantamento teórico da utilização de agrotóxicos na agricultura no município de Teresina-Piauí

Abstract

Agriculture is one of the fundamental pillars of the Brazilian economy, being responsible for a significant portion of food production relevant to food security. However, the intensive production model adopted in several regions of the country has generated warnings about the use of pesticides, especially in areas such as the rural area of Teresina, capital of Piauí. This article aimed to identify the most used active ingredients, categories, their toxicological classes, main crops and application modality used. The research was carried out from a bibliographical review and documentary data of the responsible official bodies. The results point to a predominant use of herbicides above 68%, followed by insecticides with more than 20% and fungicides, with predominance of moderately and little toxic products of classes IV and V, mainly in pastures, corn beans and watermelon. The main application modality is terrestrial via costal and treated spraying.
