Glyphosate: A Review on the Current Environmental Impacts from a Brazilian Perspective


The indiscriminate use of glyphosate is one of the main agricultural practices to combat weeds and grasses; however, its incorrect application increases soil and water contamination caused by the product. This situation is even more critical due to its great versatility for use in different cultivars and at lower prices, making it the most used pesticide in the world. Nevertheless, there is still a lack of in-depth studies regarding the damage that its use may cause. Therefore, this review focused on the analysis of environmental impacts at the soil–water interface caused by the use of glyphosate. In this sense, studies have shown that the intensive use of glyphosate has the potential to cause harmful effects on soil microorganisms, leading to changes in soil fertility and ecological imbalance, as well as impacts on aquatic environments derived from changes in the food chain. This situation is similar in Brazil, with the harmful effects of glyphosate in nontarget species and the contamination of the atmosphere. Therefore, it is necessary to change this scenario by modifying the type of pest control in agriculture, and actions such as crop rotation and biological control.
