Aquatic macrophytes are important components of aquatic ecosystems, but these plants have become a problem due to their occurrence in different regions.
Some studies aimed to demonstrate the effectiveness of herbicides to control these macrophytes; however, few studies report the possible ecotoxicological effects.
The objective of this study was to estimate the acute toxicity (LC (I)50;96h) and assess water quality variables for glyphosate in the Rodeo® formulation, Aterbane® BR surfactant and mixtures of glyphosate 0.5% and 1.0% of surfactant, for the guaru fish (Phallocerus caudimaculatus).
The guaru was exposed to increasing concentrations of glyphosate and a mixture of glyphosate 0.5...
