Description of key information

According the OECD 208 and GLP study, the chronic toxicity of the test material (EC 953-378-2) on terrestrial plants is considered at NOEC = 333 mg a.i/kg dry soil (observed on Cabbage specie after 21 days of exposure).

Key value for chemical safety assessment

Long-term EC10, LC10 or NOEC for terrestrial plants:
333 mg/kg soil dw

Additional information

Toxicity to terrestrial plants (OECD 208, GLP):


This study was conducted to determine the phytotoxic effects of the test item, on seedling emergence and growth of six non-target plant species, consisting of four dicotyledons (cabbage, carrot, lettuce and tomato) and two monocotyledons (ryegrass and onion), during early critical stages in their development. The study was considered valid as the validation criteria were met according TG OECD 208 and no visible phytotoxic effects were observed in the controls. The soil used was a sandy loam, sieved to remove all particles greater than 2 mm.


 


The EC50 values for emergence and survival were estimated to be >1000 mg a.i./kg dry soil for all plant species. The NOEC values for effects on emergence and survival were 1000 mg a.i./kg dry soil for all plant species.


The No Observed Effect Concentration (NOEC) values for height compared against the solvent control were 1000 mg a.i./kg dry soil for carrot, lettuce, tomato, ryegrass and onion. For cabbage the NOEC value was 333.3 mg a.i./kg dry soil.


The No Observed Effect Concentration (NOEC) values for dry weight compared against the solvent control were 1000 mg a.i./kg dry soil all species.
