Description of key information
NOEC (21d) = 9 kg/ha (6.89 kg a.i./ha)
Key value for chemical safety assessment
Additional information
No data on the toxicity of KDDC (CAS No. 128-03-0) to terrestrial plants were available. Therefore, a conclusion about this endpoint had to be drawn based on toxicity data from an analogue substance. The effects of ziram (CAS No. 137-30-4) on terrestrial plants were investigated by Porch and Krueger (2006a, 2006b). Both tests were conducted according to the EPA OPP 122-1 Guideline (Terrestrial Plant Toxicity Tier I), investigating the effect of this substance in seedling emergence and vegetative vigour respectively, under GLP conditions. No significant adverse effects were observed in any test after 21 days exposure at a concentration of 9 kg/ha (6.89 kg a.i./ha).
Long-term toxicity testing is not deemed necessary considering the low adsorption potential of KDDC, the fact that is readily biodegradable and the absence of toxic effects in the short-term studies performed with the analogue substance, ziram.
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.
