Abstract

VASCONCELOS, Fernanda Carla Wasner et al. MACRO simulator (version 5.0) for predicting atrazine herbicide behavior in brazilian latosols. Ciênc. agrotec. [online]. 2013, vol.37, n.3, pp.211-220. ISSN 1413-7054.  https://doi.org/10.1590/S1413-70542013000300003.

The knowledge of pesticides behavior is fundamental for understanding the environmental impact caused by these products. However, related field experiments are time consuming and expensive. The MACRO® simulator allows to predicting the leaching of pesticides through the soil profile and the possible environmental contamination. The objective of this work was to study the percolate behavior and the atrazine leaching in two contrasting Latosols using the MACRO® simulator. The MACRO® simulator was adequate to predict atrazine behavior under the studied conditions and it can be used for the risk evaluation of atrazine contamination in surface and underground waters.

Keywords : Pesticide; leaching; environmental impact.
