Description of key information
NOEC (21 d) ≥ 0.2667 mg/kg soil dw nominal (Beta vulgaris, Brassica napus, Cucumis sativus, Glycine max, Helianthus annuus, Solanum lycopersicum, Allium cepa, Avena sativa, Triticum aestivum, Zea mays, OECD 208 limit test)
Key value for chemical safety assessment
- Long-term EC10, LC10 or NOEC for terrestrial plants:
- 0.267 mg/kg soil dw
Additional information
Two GLP studies investigating the long-term toxicity of the substance are available. Both studies were conducted under controlled greenhouse conditions with ten crop plants species (6 dicotyledonous and 4 monocotyledonous species from 8 plant families) as limit tests with a single application rate of 200 g a.s./ha (corresponding to 0.267 mg a.s./kg soil dw).
In the key study (M-559339 -01 -1, according to OECD 208) seeds were sown in 15 cm pots on the day of the application of the test item to the soil surface by means of a laboratory track sprayer. Assessments were made individually for each species until 50% of the seedlings had emerged (= day 0) and after further 7, 14 and 21 days. In the controls of the ten species tested, growth was normal and no visible phytotoxicity occurred. Final assessment revealed no adverse or statistically significant effects on emergence, survival, visual phytotoxicity, growth stage development, shoot length and shoot dry weight.
In the second study (M-552710-01-1), a Vegetative Vigour Test according to OECD guideline 227 was performed. Seedlings were sown in silt loam and treated at the 2 – 4 leaf stage using a laboratory track sprayer. Final assessments were made for plant survival, visual phytotoxicity, plant growth stage shoot length and shoot dry weight after 21 days. No adverse effects above the 25% effect level were observed.Slight growth retardation and significant shoot dry weight and length reductions were observed in Lycopersicon esculentum only. All other plant species tested exhibited normal variation in the growth stage development as well as in shoot dry weight and length.
