Agribusiness, biodiversity, environmental contamination, pesticides, soybean.

With the expansion of Brazilian agribusiness linked to technological packages and the intensive
use of pesticides, impacts occur on biodiversity, especially in soybean growing areas. In the state
of Rondônia, areas cultivated with soybeans in the 2021/2022 agricultural year represented
460,119 hectares and this crop requires the use of pesticides, such as herbicides, as well as
extensive areas. The objective of this work was to analyze the expansion of agricultural areas in
the State of Rondônia, identify and quantify the main pesticides used. Information regarding the
survey and location of areas with soybean cultivation in the last 10 years, as well as the quantity
of the main pesticides used in the State of Rondônia and Municipality of Porto Velho/RO, in the
last 05 years, were extracted from the System of Inspection of the Trade of Agrochemicals in RO
(SIAFRO), managed by the Agrosilvopastoril Sanitary Defense Agency of the State of Rondônia
(IDARON). The consolidation of these data contributed to the analysis and presentation of the
spatial distribution of soybeans in the State of Rondônia and in the areas of environmental
preservation; demonstrates changes in productive behavior and economic importance and the
main active ingredients marketed, classification of use and amount destined by culture. It was
concluded that the production of commodities such as soybean, corn, coffee and pasture is the
main destination of pesticides sold in the State of Rondônia and in the Municipality of Porto
Velho and that glyphosate, either pure or in its compositions, is the main active ingredient,
representing 50% of all volume sold in the last 05 years.
