For this purpose, four plants of L. minor and five of A. caroliniana were selected in a 50 mL Hoagland medium. For both plants, the following concentrations were used: 0.10; 1.07; 3.44; 11.16; 36.40 and 118.0 mg L-1 of each test product and a control with three replicates. The results of this study demonstrated higher sensitivity of L. minor to the tested pesticides, when compared to A. caroliniana. L. minor can be used in the monitoring of herbicides bentazon, atrazine and clomazone and pyraclostrobin-based fungicide, and A. caroliniana can be used for pyraclostrobinbased fungicides, due to the sensitivity of these organisms when exposed.597-603engbioindicationaquatic plantsacute toxicityenvironmental monitoringpesticideArtigo10.1590/S0100-83582016340300021S0100-83582016000300597WOS:000384150400021Acesso abertoS0100-83582016000300597.pdf
