- Abstract
The growing demand for food made it necessary to introduce agrochemicals to increase agricultural production efficiency. However, when used incorrectly, these products cause severe damage to the environment and human health. The objective of this work was to evaluate the residual of thiamethoxam (molecule widely used in insecticides from seed treatment to the advanced stage) in a eutrophic red Argisol, widely used for soybean cultivation in the Central region, Rio Grande do Sul. For this evaluation, soil harrowing was carried out, in order to leave it without vegetation, application of Thiamethoxam, collection and analysis of samples for the physical-chemical parameters of the soil and residual concentration of the compost. With the accomplishment of this study, it was observed that the soil and meteorological characteristics of the region favored the dissipation of the thiamethoxam molecule in the soil solution. From 30 days after application of Thiamethoxam, there was no more residue of this molecule in the soil solution.
