The 48 hours acute toxicity of ITC 826 Concentrate (purity: 69,1%) to Daphnia magna was studied under static conditions.  Daphnids were exposed to control and test chemical at nominal concentration from 1,3 to 41 mg/L (based on test material excluding water) for 48h. Immobilization was observed daily. The 48 hours EC50was 6,5 mg/L.
