Abstract

The current paper investigates toxicological effects of fungicidal formulations based on pyraclostrobin, epoxiconazole and a combined formulation to Colossoma macropomum (tambaqui) during 96 hours by determination of Mean Lethal Concentration (LC50-96h) of each formulation. LC50-96h values found were 0.018 mg L-1, 2.28 mg L-1 and 0.021 mg L-1 for pyraclostrobin, epoxiconazole and combined formulation, respectively. Pyraclostrobin isolatedly was the most toxic chemical among analyzed formulations and the combined use of those two fungicides presented a weak synergic effect, regarding the concentration tested.
