Description of key information

Of six recommended test species of plant the most sensitive to the test substance was the monocot. Brassica napus (rape) with an (14 d) EC50 (growth) value of 0.21 mg/kg, a NOEC (growth) of 0.12 mg/kg and a LC50 of 0.26 mg/kg. No significant effects on seedling emergence were found for any of the species tested.

Key value for chemical safety assessment

Additional information

An acute toxicity test is available for this study, in accordance with the prevailing OECD testing guidelines (208), with GLP. Six recommended plant species were used to test for seedling emergence and growth. The NOEC (14d) values for seedling emergence ranged from > 1.08 to > 32.4 mg test substance/kg. In all cases this equated to the highest concentration tested for each species and hence no significant effects of seedling emergence could be determined. The (14 d) EC50 values for seedling growth ranged from 0.21 to 1.51 mg test substance/kg and the NOEC values ranged from 0.12 mg/kg to 0.40 mg/kg. The most sensitive species used in this study was the monocot. Brassica napus (rape), with an EC50 (growth) of 0.21 mg/kg and an LC50 of 0.26 mg/kg (Simon, 2009).
