Toxicity to terrestrial plants


This study is read across to Phenol, isopropylated, phosphate (3:1); CAS No 68937-41-7; EC No 273-066-3. Justification is provided in the relevant study section.

The effects of Durad 310M, incorporated into soil at concentrations of 100, 10, 1 and 0 mg/kg, upon the germination (emergence) and growth of seedlings of wheat (Triticum aestivum), radish (Raphanus sativus)and mung bean (Phaseolus aureus) were determined over periods of 19, 18 and 19 days respectively, representing 14 days after at least 50% emergence of control seedlings.


The LC50 for emergence and EC50 for growth rate were both greater than the highest concentration tested, 100 mg/kg, in all species.


No phytotoxic effects were observed for any of the species tested.


In accordance with column 2 of REACH Annex X, Long-term toxicity testing shall be proposed by the registrant if the results of the chemical safety assessment according to Annex I indicates the need to investigate further the effects of the substance and/or degradation products on terrestrial organisms. The choice of the appropriate test(s) depends on the outcome of the chemical safety assessment.

Based on the lack of toxicity within the short term plant study on an analogous material, and the fact that risk recommendations are implemented to avoid exposure to the environment, it is proposed that a long term toxicity test in plants is not required.
