The acute toxicity to Daphnia magna was determined in a 48-hour static test according to the OECD Guideline for Testing of Chemicals, Section 2, No. 202, adopted 4 April 84, the EEC Directive 84/449, L 251, Part C 2, and to the Guideline of the U.S. Environmental Protection Agency, Pesticide Assessment Guidelines, Subdivision E, EPA-540/9-85-005, June, 1985.
The test was performed in compliance with the Good Laboratory Practice Regulations. The nominal concentrations tested was 15.6, 31.3, 62.5, 125 and 250 mg test article/l and a control without any additions.
24h EC 0: 31.3 mg test article/l
24h EC 50: 164.9 mg test article/l (95 % conf. limits 143.6 - 189.5 mg test article/l)
24h EC 100: 250.0 mg test article/l
48h EC 0 < 15.6 mg test article/l
48h EC 50: 55.0 mg test article/l (95 % Conf. limits: 38.5 - 78.6 mg test article/l)
48h EC 100: 250.0 mg test article/l
All reported results are related to nominal concentrations of the test article. During test duration the active ingredient concentrations were in the range of 102.6 - 110.6 % of the nominal values, under test conditions the test article was sufficiently stable.
EC50(48h) = 55 mg/l
