Additional information

One valid test with algae is available. In the test following OECD guideline 201 Pseudokirchnerella subcapitata was exposed to the substance for 72 hours. Based on the algal growth rate an EC50 of 220 mg/l (NOEC 40 mg/l) was determined at test termination. The results refer to the nominal test concentration based on substance mass without correction for purity (BASF SE 2010). Corrected for active ingredient, the results were EC50 (72h) 165 mg/l and NOEC (72h) 30 mg/l rsp.

One further elderly study tested according to a national guideline with Sc. subspicatus exists but does not fulfill the quality criteria.
