The effects of sodium salt of 2.4-Dichlorophenoxi-acetic acid (2.4-D-Na) on the mortality and reproduction of Daphnia magna have been tested. The mortality tests were performed in experiments with duration time of 24, 48 and 96 h at the temperatures of 15 and 20 °C. The toxic effect increased by 11-16 regarding 47% with increasing of temperature and exposure time. This herbicide (Dikonirt) affected adversely the reproduction of daphnids at concentration lower than tenth of LC50 value.
