Additional information
The toxicity of the test substance on terrestrial plants was tested in a GLP study according to OECD guideline 208 [BASF AG, 2001]. This OECD 208 guideline is designed to assess the potential effects of substances on seedling emergence and growth. Therefore, it is specific to a part of the plants life-cycle and does not cover chronic effects on reproduction, however it is assumed to cover a sensitive stage in the life-cycle of a plant and therefore data obtained from this study have been used as estimates of chronic toxicity [ECHA, Guidance on information requirements and chemical safety assessment, chapter R.7c].
Emergence and growths on oats (Avena sativa), oilseed rape (Brassica napus) and vetch (Vicia sativa) were determined. The most sensitive acute EC50 value (19 d) was 794 mg/kg soil (d.w.) for Avena sativa. No chronic effects were observed up to a test concentration of 250 mg/kg soil (d.w.).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
